ct scan in central oregon

What to Expect During Your CT Scan in Central Oregon

Computed tomography (or CT) scans provide a three-dimensional view of your bones, blood vessels, and soft tissue. This allows doctors to have a better look at your head, heart, lungs, abdomen, and digestive system. If your doctor has requested a CT scan in Central Oregon, schedule your appointment with Central Oregon Radiology Associates (or CORA). We provide more than a dozen types of CT scans specific to your needs.

Here’s What You Need to Know About Your CT Scan in Central Oregon:

How It Works

A CT scan uses X-ray technology to create a three-dimensional image of your bones, blood vessels, and organs. This allows us to diagnose infectious diseases, musculoskeletal disorders, appendicitis, heart disease, and cancer. It works by taking multiple X-rays of your body from multiple angles. Afterwards, digital processing is used to generate an 3-D image of your internal anatomy.

Types of CT Scans

There are several different types of CT scans available depending on what your doctor needs to see. At CORA we offer the following CT services:

How To Prepare

No matter which part of your body is being scanned, there are a few things you need to be aware of before your appointment. First, please let us know if you are taking any medications or have any allergies. It’s also important to disclose if you smoke, if you have diabetes, or if you have a family history of certain ailments. If you are breastfeeding, if you have kidney problems, if you have recently been sick or you have recently had surgery, please let us know that as well.

On the day of the scan, it’s important that you’re comfortable. Wear loose fitting clothing and avoid wearing any jewelry. Metal items may interfere with the results and so we ask that you refrain from wearing any accessories including jewelry, glasses, hairpins, underwire bras, hearing aids, and removable dental work. You may also need to avoid eating or drinking beforehand depending on the exam.

What To Expect

When you arrive for your CT scan, we may have you change into a gown. Some patients will require the use of a contrast to make the images easier to read. If this is the case you will be placed on an IV containing the contrast fluids. If we will be scanning a joint, a contrast medium may be injected into the joint.

From there you will be placed on an examination table and asked to remain still. This is important as the machine will not be able to produce a quality image if you are moving. The table will then slide into a large opening on the front of the machine. It may move you through the machine several times, or it may move you through once slowly. This may take from less to one minute up to fifteen minutes total.

Once your scan is complete, we may ask you to wait while we verify the image quality of the scan we just finished. When confirmed, you are free to go about your day with no downtime.

Schedule an appointment for your CT scan in Central Oregon. We’ll make sure you are well taken care of and that the process goes as smoothly as possible.

3d ultrasound in central oregon

Getting Your 3D Ultrasound in Central Oregon

Ultrasounds use a transducer or probe to see the soft tissue inside of the body. Typically this results in a two-dimensional image produced by scanning through one “slice” of your body. However, by taking several two-dimensional images, a three-dimensional image can be created for a complete view of your body. This can be used to view internal body structures such as muscles, tendons, joints, organs, and blood vessels. Perhaps most popularly, they can be used to monitor an unborn child during pregnancy. Schedule your appointment to get your 3D ultrasound in Central Oregon.

Here’s What You Need to Know About Getting Your 3D Ultrasound in Central Oregon

How It Works

Ultrasound equipment works by emitting sound waves at a very high frequency. So high it cannot be heard by human ears. These sound waves are pulsed into the body using a probe. When the sound bounces off your interior tissue and organs, the results are recorded via a digital image.

There are many advantages to getting an ultrasound. Unlike an X-ray, it does not use any radiation—this is what makes it such a great way to check in on your baby during pregnancy. It is also a great way to take a look at your anatomy and do some problem solving. Better yet, 3D Ultrasounds are mobile and thus able to be used on many occasions in many locations.

How To Prepare

A doctor may request your for diagnostic purposes. If so, schedule your ultrasound appointment and heed your doctor’s recommendations. You may be required to drink a certain amount of fluids prior to your ultrasound.

What To Expect

During your appointment, you may be asked to undress, or partially undress. A technician will then apply a warm gel to your skin as well as to the probe to close any gaps between the tool and your body. By moving the probe around your skin, an image can start to be produced on the screen. Though the process is the same as a two-dimensional ultrasound, the computer will be processing it differently allowing a three-dimensional image to appear.

During the ultrasound, you will be able to see the interior of your body—or your baby—as it is in real-time. There may be movement or even sound. You may be asked to hold your breath for a better quality image. After the exam, the technician will wipe off the gel, and you will be ready to go about your day with no downtime.

Schedule Your 3D Ultrasound in Central Oregon

Central Oregon Radiology Associates (or CORA) provides 3D ultrasounds at all of our locations in Bend, Madras, Prineville, and Redmond. Schedule your appointment—we’d love to show you the magic of 3D ultrasounds in Central Oregon.

Prostate Embolization

Revolutionary Prostate Embolization Treatment Comes to CORA

CORA strives to be a leader in revolutionary medical treatments and interventional radiology. We are pleased to now offer Prostate Embolization, a groundbreaking new way to treat enlarged prostates in older men without invasive surgery.

What Does Prostate Embolization Treat?

Many men develop enlarged prostates as they age. This condition is called Benign Prostatic Hyperplasia, or BPH. BPH is often accompanied by urinary tract symptoms including waking up several times at night to use the bathroom, incontinence, difficulty urinating, and incomplete voiding.

When a man has BPH, his prostate gland grows. In order for this to happen, the prostate requires a steady supply of blood. These symptoms have traditionally been treated surgically with a TURP (trans-urethral resection of the prostate). However, TURP is an invasive procedure with a lengthy recovery and potential complications including bleeding and sexual dysfunction.

However, scientists have recently developed a technique called Prostate Embolization, a minimally invasive procedure that can be performed on an outpatient basis. This procedure, also referred to as Prostatic Artery Embolization or PAE, is a day procedure with very little pain and a high success rate.

How Does it Work?

PAE is done from the artery in the wrist in the majority of cases. The procedure involves placing tiny beads in the arteries that bring blood to the prostate. These beads decrease the flow of blood, which causes the prostate to decrease in size. This alleviates the previously existing urinary symptoms.

How Effective is Prostate Embolization?

As a new procedure, more data is being generated on PAE all the time. However, medical studies show that PAE produces positive results. Recent data suggests that it is as effective as TURP while resulting in a shorter recovery time and fewer side effects. PAE has been proven to be safe and effective in a growing number of studies worldwide.

Prostate Embolization at CORA

PAE is currently being performed by a very limited number of physicians in the United States and is gradually becoming more available around the world. This procedure has evolved into an encouraging and minimally invasive option for patients suffering from a wide variety of prostate issues, from BPH to lower urinary tract symptoms (LUTS).

Many of our radiologists at CORA have specialized in interventional radiology and are ready to help treat your symptoms with leading-edge treatments and high-quality care. To schedule an appointment or learn more, please contact your team at CORA.

breast cancer awareness month

National Breast Cancer Awareness Month

October is National Breast Cancer Awareness Month, a campaign put on by the National Breast Cancer Foundation to raise awareness and funding for breast cancer and breast cancer research. The goal of the foundation is to eradicate breast cancer through prevention, education, and early detection. We at CORA would like to do the same.

Inspired by National Breast Cancer Awareness Month, Here Are a Few Things You Can Do Help Fight Breast Cancer:

Get Educated

The National Breast Cancer Foundation was formed to educate women about breast cancer. As breast cancer affects one in eight women, one of the most important things an individual can do is take the time to educate themselves about it. For instance, did you know that your risk of getting breast cancer is increased if you are Caucasian, over the age of 55, or have a family member who has had breast cancer?

There are also several lifestyle factors that can increase your risk of breast cancer. If you started menstruation before the age of 12, started menopause after the age of 55, had a child later in life, or never had a child, your risk of developing breast cancer increases. Likewise, there are several genetic factors that can increase your chances. Gene mutations (such as BRCA1 and BRCA2) or dense breast tissue can be contributing factors. Read this guide to learn more and assess your risk.

Learn Early Detection Methods

Thankfully, there are several things you and your family members can do to detect breast cancer earlier. One way is to perform monthly breast exams in the comfort of your own home. While you are in the shower, move your fingers around your breasts in a circular motion. If you notice lumps, knots, or changes in how the breast or nipple looks or feels, schedule a physical with your physician.

During a clinical exam, your doctor may take a visual scan of the breast, followed by a manual exam. In both cases, they will look for physical abnormalities that need to be investigated further. Generally, what they are looking for are small, pea-sized lumps that move around easily. Though it is important to be aware of changes in your breasts, there is need to panic; 8 out of 10 lumps are not cancerous and pose no cause for concern.

Get a Mammogram

Though self-exams are an important part of maintaining your breast health, the most beneficial thing any woman can do to catch cancer early is get a mammogram. Mammograms are x-rays that can detect cancerous tumors before they can be felt. No matter your age, if you have any risk factors for developing breast cancer, it is important to get a mammogram regularly. If you are over the age of 40, you should get a mammogram every 1-2 years regardless of whether or not you are experiencing any symptoms or abnormalities.

At CORA we provide a variety of imaging services including 3D mammograms, breast MRIs, and breast ultrasounds. Our advanced 3D imaging options allow us to detect 41% more invasive breast cancers by taking pictures of the breast from every angle. We are the only breast center of excellence certified in all types of breast imaging by the ACR. Schedule an appointment—getting a mammogram is one of the most important things you can do for your breast health during Breast Cancer Awareness Month.

interventional radiology

What is Interventional Radiology?

Central Oregon Radiology Associates P.C. (CORA) has recently added two new Interventional Radiologists, Dr. Ben English and Dr. Marco Ugas, to our staff. These doctors bring top-notch training and the latest minimally invasive image-guided techniques to safely address problems throughout the body. But what exactly is interventional radiology? Learn frequently asked questions and their answers below.

Why Haven’t I Heard of Interventional Radiology Before?

Interventional radiology goes by a few different names and is a relatively new development in the medical field. Vascular and interventional radiology (VIR), also known as interventional radiology (IR), is a medical subspecialty that provides minimally invasive and image-guided diagnosis and treatment of various diseases. IR procedures are at the forefront of medical technology development. CORA’s doctors use IR to offer a safe and proven alternative to open surgery with significantly less recovery time than traditional surgical methods.

Why Should I Choose Interventional Radiology Over Surgery?

In many instances, an IR procedure is a quicker, safer, and better alternative to surgery. The vast majority of IR procedures are performed as day procedures with a minimal recovery period. Incisions are rarely necessary and general anesthesia is usually not required.

Since IR treatments are minimally invasive, a typical patient will have a swift recovery with little or no hospital stay. IR procedures offer a safe, effective, and patient-friendly alternative to traditional surgery.

What Issues Can Interventional Radiology Treat?

There is a broad range of procedures performed by our interventional radiologists. However, the unifying concept is the application of image guidance paired with minimally invasive techniques to minimize patient risk.

Our radiologists at CORA use interventional radiology techniques to treat peripheral vascular disease (claudication), open up other blockages (veins, bile ducts, ureters, etc.), destroy tumors by delivering local chemotherapy, embolization, or ablation (liver, lungs, kidney, uterus), stop bleeding, treat aneurysms/AVM’s, drain fluid collections from various regions in the body, and more.

Our team of certified professionals at CORA is here to help you understand more about vascular and IR services. If you’d like to learn more about the benefits and risks of IR procedures, how to prepare, and more, please give our office a call today.

Medical Imaging Facility on Bend's South Side

CORA Opens New Medical Imaging Facility on Bend’s South Side

The staff and doctors at Central Oregon Radiology Associates P.C. (CORA) are excited to announce the opening of our new medical imaging facility on Bend’s south side. Our new state-of-the-art facility on the south side is located off 3rd Street, across from Bend’s outlet mall.

State-of-the-Art Technology with a Spa-Like Atmosphere

Our newly constructed imaging center is designed to enhance patient comfort while offering the most advanced imaging technology available in the field of radiology. This location offers spacious design and a comfortable, spa-like atmosphere with features supporting MRI, advanced CT, x-ray, ultrasound, and 3D mammography.

The MRI lighting selected for diagnostic environments can have a big impact on a patient’s experience during his or her medical exam. For instance, while daylight offers significant emotional benefits to patients, it’s often overlooked since inward-facing planning is typically an unavoidable part of building design.

Our MRI exam rooms are equipped with MRI lighting by Sky Factory to restore the spatial component of natural daylight during a scan with new technology. This is a powerful therapeutic element that brings comfort and serenity to scanning sessions by reconnecting patients as well as staff with a view of nature and open skies. Our lighting increases patient relaxation, reduces anxiety and claustrophobia, generates higher patient satisfaction scores, and raises staff wellness and productivity.

Why Bend’s South Side

At CORA, we are always striving to expand our services in Central and Eastern Oregon so that we can care for those in need of radiology services from ultrasounds to x-rays. With convenient parking, quick patient turnaround, and top-notch radiology interpretations provided by our doctors, our new medical imaging facility on Bend’s south side will help us provide outstanding care to our community.

Our goal is to support the growing need for medical imaging for all Bendites as the population of our city continues to grow.


Our new medical imaging facility on Bend’s south side is just off Hwy 97 across from the Bend Factory Stores on the corner of 3rd and Badger. It is north of Walmart and right next door to St. Charles Family Care Bend South.

Curious about what else our new facility has to offer? Give us a call or swing by to see our Bend’s south side location with your own eyes. For more information, please visit Cascade Medical Imaging.

National Breast Cancer Awareness Month

Every month of October since 1985 has been known as National Breast Cancer Awareness Month.


Over the course of this month, many organizations and individuals will come together to spread knowledge and awareness of breast cancer prevention, detection, and treatment, as well as provide support to those who have been affected by breast cancer and to celebrate the tenacity and resilience of breast cancer survivors.

Because of the relatively common occurrence of breast cancer, many people have a personal connection to its effects through a diagnosis of a friend, a family member, or themselves. According to the Centers for Disease Control (CDC), breast cancer is the most common cancer found in women of all races and ethnicities.

Over 230,000 people are diagnosed with breast cancer per year, and the vast majority of them are women.

There are several steps one can take to minimize the risk of a breast cancer diagnosis, including regular exercise, a balanced and healthy diet, and avoiding exposure to radiation or carcinogenic chemicals such as smoking.
Perhaps even more important to reducing the potential impact of breast cancer, however, is getting screened for it regularly.

Schedule a Screening

Call Central Oregon Radiology at 541-382-9383

The United States Preventative Services Task Force recommends that any woman over 40 ask a doctor about breast cancer screenings, and that women between 50 and 74 undergo a mammogram or breast MRI once every two years at minimum.


Early detection of breast cancer can be life-saving, as catching the disease earlier reduces the severity of treatments and increases survival rates, as well as the chances of it spreading to other parts of the body.

According to the American Cancer Society, those who detect breast cancer in its early stages have a near 100% survival rate, as well as a 50 to 75 percent higher rate of survival than those who detect it later.


CORA offers breast screening services including 3D digital mammography and breast MRI, as well as a full complement of imaging services specifically for women’s health.

The 3D digital mammogram, also known as a digital breast tomosynthesis, is a revolutionary new tool that reduces false positive tests by up to 40% as well as increasing the amount of invasive cancers detected by 41%. Making an appointment with the fellowship-trained physicians and technicians at CORA is easy and fast, and same-day appointments are often available.

About Screening Mammography Guidelines

Central Oregon Radiology Associates (CORA) recognizes that there are conflicting guidelines for screening mammography and that these conflicts can be a source of confusion for patients and providers alike.

Central Oregon Radiology Associates seeks to provide quality, evidence-based information for clinicians and patients in the Central Oregon region. With this in mind, Central Oregon Radiology Associates offers the following clarification and position regarding screening mammography recommendations:
Mammography remains the best tool available to screen for breast cancer. It has helped reduce the breast cancer death rate in the United States by 30 percent. Currently, insurance coverage for annual screening mammograms beginning at age 40 is mandated.

Central Oregon Radiology Associates continues to follow and support the American College of Radiology (ACR) guidelines that recommend women aged 40-80 have yearly mammograms. These guidelines are also supported by the Society of Breast Imaging (SBI), American Society of Breast Disease (ASBD), and the American College of Obstetrician and Gynecologists (ACOG).

Recently, the American Cancer Society (ACS) has made screening recommendations for average risk women, i.e. women with no significant risk factors and/or a calculated lifetime risk of developing breast cancer of 12% or less. For these average risk women, and after a discussion with their doctors, the ACS allows that annual screening mammography can begin at age 45, and bi-annual mammography might be considered after the age of 55, again after a risk evaluation and discussion with a clinician. However, the ACS also states that if a woman desires, she should have access to annual mammograms beginning at 40.

The US Preventive Services Task Force (USPSTF) also has made screening recommendations which are controversial and which could limit access to screening mammography as insurance companies are allowed to provide coverage based on USPSTF recommendations. The USPSTF recommends screening mammography starting at age 50 and continuing through age 74, and only on an every-other-year basis.

Through the end of December 2017, there is a two-year moratorium on the USPSTF’s recommendations thanks to the bi-partisan Protecting Access to Lifesaving Screenings (PALS) Act, allowing women access to annual screening mammograms beginning at 40.
At CORA, we want be an integral part of developing a screening plan based on a woman’s risk and needs by providing a risk assessment at the time of a her mammogram. We are also working for continued access to potentially life-saving screening, to help ensure the health and wellbeing of our valued patients.

Please contact us at CORA with any questions when making breast health decisions.

Sir Godfrey Hounsfield, Inventor of Computed Tomography

This week we’re recognizing electrical engineer, and x-ray computed tomography (CT scan) inventor, Sir Godfrey Hounsfield. Hounsfield helped design the first commercially available all-transistor computer made in Great Britain: the EMIDEC 1100 in 1958. Hounsfield invented what is now known as a CT scan machine (x-ray computed tomography) and successfully scanned a live patient in 1971. Hounsfield’s name is also immortalized by the Hounsfield scale, which is a measure of radiodensity used in evaluating CT scans. (source
