Imaging Services

Radiologists Eugene OR | Springfield OR

The Oregon Medical Group Imaging Services Department and Cedar Clinic opened in 1999. Our goal in imaging is to provide the most advanced diagnostic imaging services available for our patients and referring physicians.

What began as a single ultrasound machine and an xray unit has grown into a comprehensive multi-modality medical imaging center with an accredited all-inclusive breast center (the Cedar Clinic) with equipment that is unequaled in Lane County. We see over 50,000 patients a year for imaging exams and procedures.

Oregon Medical Group's Cedar Clinic is a certified and accredited health care facility that focuses on total breast care; including screening, diagnosis and treatment. Our approach to breast health is somewhat unique in Lane County; we deliver mammogram test results within a day. We also offer appointments that will accommodate your schedule, whether that means early or late. Our team of physicians work together to follow each patient through our care program, from initial mammogram to treatment plan, if necessary. Our nurses and staff are qualified professionals who have the sensitivity to guide you gently through your procedure. This comprehensive approach ensures our patients feel well cared-for throughout their time with us.

At Oregon Medical Group's Imaging Center, we understand how important high quality radiology is to our patient's health. That's why we are the leader in full service, out-patient imaging. Not only do we offer the most technologically advanced imaging resources in the area, but an unprecedented level of exceptional service to you and to your family.

Patient Education

Oregon Medical Group Imaging Services offers a full range of highly specialized and innovative imaging modalities at their clinics throughout Eugene and Springfield including:

Digital Diagnotic Imaging (radiography)

Diagnostic X-ray is the original modality from which the field of radiology developed, and is the most common tool employed in radiology. X-rays can be either still images or "movies," also know as Fluoroscopy, and can often be done quickly. They are frequently used to complement other kinds of radiological procedures. Learn more about preps for diagnostic X-ray (radiography) exams. X-Ray services are available at:

CT (Computed Tomography)

Computed Tomography (CT) imaging combines the use of a digital computer and a rotating x-ray device to create detailed cross-sectional images or "slices" of the different organs and body parts.CT is one of the best tools for studying the lungs and abdomen. CT is an invaluable tool in the cancer diagnosis process. Learn more about the preps for computed tomography exams. CT services are located at Country Club Road Medical Center.

MRI (Magnetic Resonance Imaging)

Magnetic Resonance Imaging or MRI is one of the most comprehensive diagnostic tools available to physicians. MRI uses radio waves and a strong magnetic field rather than x-rays to provide clear and detailed pictures of internal organs and tissues. the MRI scanner reconstructs data into images that are usually displayed as "slices" through the body. Images are formed in three different cross-sections and can be linked together to show a 3-dimensional picture of the bone, internal organs or other tissue structures within the body. MRI has proven valuable for the diagnosis of a broad range of conditions, including cancer, heart and vascular disease, stroke, and joint and musculoskeletal disorders. Learn more about preps for MRI exams. MRI services are located at Country Club Road Medical Center.


A mammogram is a set of X-ray images of the breasts. A screening mammography is performed on women without symptoms. The purpose is to look for any early signs of breast cancer. The majority of these mammograms show no abnormality. A diagnostic mammography is performed to resolve a particular question related to the breast. Learn more about preps for mammography exams. Mammography services are located at Country Club Road Medical Center and Center for Women's Health (Chase Gardens Medical Center - North).

Nuclear Medicine

Nuclear medicine is an Imaging subspecialty often used to image the body and treat disease. It is unique because it provides doctors with information on organs and their function. A machine called a gamma camera detects radioactive material which has been introduced into the patient's body (usually by injection) for the nuclear medicine test.Nuclear Medicine is different from other imaging procedures in that it often allows for diagnostic information to be obtained prior to the onset of physical symptoms. Learn more about preps for nuclear medicine studies. Nuclear Medicine imaging services are located at Country Club Road Medical Center.


Ultrasound exams are used to produce an image of the internal structures of the body, and are performed with the use of an ultrasound beam (very high frequency sound waves). As the beam passes through tissues, an echo will bounce off structures in your body and a computer in the ultrasound scanner displays the echo images on a monitor. These images are done "real time," which means that the sonographer is able to see the structures in your body on the screen while you are breathing and moving. Learn more about preps for exams. Ultrasound services are located at Country Club Road Medical Center, West Eugene Medical Clinic and Center for Women's Health (Chase Gardens Medical Center - North).

Bone Densitometry

Bone Densitometry is a radiology procedure that determines bone mineral density or bone mass. Bone mineral measurements are very highly correlated with bone strength, and have been shown to predict the potential or risk for bone fractures. Learn more about preps for bone densitometry exams. Bone Densitometry services are located at Country Club Road Medical Center.

Frequently Asked Questions

What is CT Scanning?
CT scanning, also called computed tomography or computerized axial tomography (CAT scan), is an X-ray test used for diagnosis. X-rays are taken from a series of different angles and arranged by a computer to show a cross-sectional view of organs in the body.
How do I prepare for a CT scan?
Your Imaging team will give you specific instructions for your exam, based on the type of procedure ordered.
What happens during the procedure?
CT scanning will be done at our Imaging Center at 920 Country Club Road, Suite 100A. You will lie down on a moving table, which will slide you into the tunnel-like scanning machine. The scanner can move around you to change the angles of the X-rays.Inside the scanner, multiple X-ray beams are passed very quickly through your body at different angles. The images are projected onto a TV screen and prepared for your healthcare provider to examine.A solution of dye (also called contrast media) may be injected into a vein, or you may be asked to swallow the solution. This allows the scanner to show specific areas as the dye passes through your body.Scans may last 3 to 20 minutes. They are painless, but you may get uncomfortable from lying in the scanner, if the scan takes more than a few minutes. You can talk to the technologist at any time during the procedure.
What happens after the procedure?
If you were given dye for the scan, drinking a lot of fluids after the procedure may help your body get rid of the dye. Rarely some people have an allergic reaction to the dye. Most reactions happen right away, but you could have a delayed reaction. After a CT scan that uses dye, watch for signs of a reaction. These signs include itching, rash, or sweating. If you start having these symptoms, call your healthcare provider right away. If your throat gets swollen or you have trouble breathing, call 911 for emergency medical care.
What are the benefits of this procedure?
A CT scan provides detailed pictures to help your healthcare provider diagnose your problem.
What are the risks associated with this procedure?
In this procedure your body is exposed to a very small amount of radiation. Exposure to radiation can be dangerous if you are exposed to it often or in large amounts. Oregon Medical Group is committed to radiation safety and uses standard dose reduction techniques to limit the amount of radiation you receive during your test.If you are pregnant, you should not have a CT scan without first discussing the possible risks with your healthcare provider.There is a small risk that you will have an allergic reaction to the dye. For example, there is a chance you will be allergic to the dye if you have a shellfish allergy. Even if you are not allergic to the dye, the dye may cause warm feelings, a flushed face, headache, or a salty taste in the mouth. Rarely, it can cause nausea and vomiting.Be sure to tell your healthcare provider if you know you are allergic to any medicines or chemicals such as iodine.
When should I call my healthcare provider?
Call your provider right away if:

  • You have a worsening of the pain or other symptoms you had before the test.
  • You are having symptoms of an allergic reaction: itching, rash, or sweating. If your throat is swollen or you have trouble breathing, call 911.

Call your provider during office hours if:

  • You have questions about the procedure or its result.
What is Magnetic Resonance Imaging (MRI)?
Magnetic resonance imaging (MRI) is a special test that produces very clear, detailed pictures of the organs and structures in your body. The test uses a powerful magnetic field, radio waves, and a computer to create images in cross-section. While an X-ray is very good at showing bones, an MRI lets your healthcare provider see structures made of soft tissue such as ligaments and cartilage and organs such as your eyes, brain, and heart.
When is it used?
Injuries show up well on an MRI. For example, an MRI may show whether you have torn ligaments or torn cartilage in your knee and help your healthcare provider decide whether or not you need surgery. It is also useful for injuries involving the shoulder, back, or neck. Healthcare providers use MRIs to see problems in the brain and spinal cord and to see the size and location of tumors.
How do I prepare for the procedure?
Your Imaging team will give you specific instructions for your exam, based on the type of procedure ordered. Do not wear jewelry. If you have any metal in your body (such as plates or screws from a previous surgery) tell your healthcare provider. If you have a pacemaker you will not be able to have an MRI. If you have any metal fragments in or around your eyes you cannot have an MRI because the test may injure your eyes. If you have anxiety or claustrophobia (difficulty with small or crowded spaces), let your provider know.
What happens during the procedure?
You lie down on a cushioned bed that moves into a magnet that is open on both ends. If you get nervous when you are in small closed spaces you should talk to your healthcare provider about this before you have your MRI to either schedule in our Open MRI or receive medication to relax. He or she may be able to give you a medicine that will help you feel less nervous or may insist that you are scanned in our open MRI scanner. You will have to be very still during the procedure so the pictures will not be blurry.Sometimes you are given a shot of a fluid called gadolinium before getting an MRI. This causes any abnormal areas to become very bright on the MRI. This makes them easier to see.Most MRIs take between 25 and 40 minutes. You will hear loud knocking and a whirring sound while the pictures are being taken. You will wear earplugs or music will be provided so that the noise doesn't sound so loud. You will be able to speak with the person doing the test through a sound system so you can let him or her know if you are having any problems.When the test is over you may go home. Your healthcare provider will schedule a visit with you to discuss the results.
What are the benefits and risks?
An MRI is painless. There is no radiation. If you were given a shot of gadolinium, there is a chance you will have an allergic reaction, but this is very rare.
Although there is no evidence that an MRI will hurt a baby during the first trimester of pregnancy, the National Radiological Protection Board recommends not using it at this time of pregnancy. MRI may be used safely later in pregnancy.
What is ultrasound (sonography)?
Ultrasound (also called sonography) is a diagnostic medical procedure that uses high-frequency sound waves to produce dynamic visual images of organs, tissues or blood flow inside the body. The high-frequency sound waves are transmitted to the area of interest and the returning echoes recorded. This type of procedure is often referred to as a sonogram or ultrasound scan.First developed in World War II to locate submerged objects, the technique is now widely used in virtually every branch of medicine.Sonography can be used to examine many parts of the body, such as the abdomen, breasts, female reproductive system, prostate, heart and blood vessels and more.In obstetrics ultrasound is used to study the age, number, and location of the fetus, as well as to examine the fetus for birth defects or other potential problems. In the abdomen, it is used to detect abnormalities such as gallstones or liver disease. Heart disease can be identified through cardiac ultrasound. Ultrasound can also be used for therapeutic purposes such as muscle/joint heating and lithotripsy (a procedure used to break up kidney stones).Sonography is increasingly being used in the detection and treatment of heart disease, heart attacks and vascular disease that can lead to stroke. It is also used to guide fine-needle tissue biopsy to assist in taking a sample of cells from an organ for lab testing (for example, a test for cancer in breast tissue).Diagnostic ultrasound is noninvasive, involves no radiation, and avoids the possible hazards, such as bleeding, infection, or reactions to chemicals of other diagnostic methods.The non-physician professionals who perform these procedures are known as sonographers and vascular technologists (sonographers specializing in imaging and tests of blood vessels).
What Happens in an Ultrasound Exam?
The sonographer applies an odorless, colorless gel to the skin above the body structure(s) to be studied. This gel helps conduct sound waves from the ultrasound transducer down to the tissues that are the focus of the study. The sonographer applies the transducer to the skin and short pulses of ultrasound waves are emitted and received.As the transducer is moved around, an image of the various organs under study appears on a monitor. The sonographer then electronically stores what he or she considers to be the most diagnostically useful images. Selected images are used by an interpreting physician to make a final diagnosis.Sonographers may also have managerial or supervisory responsibilities.
What is Radiography (X-ray)?
X-rays are a form of electromagnetic radiation, just like visible light. In a health care setting, a machine sends individual x-ray particles, called photons. These particles pass through the body. A computer or special film is used to record the images that are created.Structures that are dense (such as bone) will block most of the x-ray particles, and will appear white. Metal and contrast media (special dye used to highlight areas of the body) will also appear white. Structures containing air will be black and muscle, fat, and fluid will appear as shades of gray.
How is the test performed?
The test is performed in the Imaging Center or in the provider's office by a registered x-ray technologist. The positioning of the patient, x-ray machine, and film depends on the type of study and area of interest. Multiple individual views may be requested.Much like conventional photography, motion causes blurry images on radiographs, and thus, patients may be asked to hold their breath or not move during the brief exposure (about 1 second).
How should I prepare for the test?
Inform the health care provider prior to the exam if you are pregnant, may be pregnant, or have an IUD inserted.You will remove all jewelry and wear a hospital gown during the x-ray examination because metal and certain clothing can obscure the images and require repeat studies.
How will I feel during the test?
There is no discomfort from x-ray exposure. Patients may be asked to stay still in awkward positions for a short period of time.
What are the risks?
For most conventional x-rays, the risk of cancer or defects due to damaged ovarian cells or sperm cells is very low. Most experts feel that this low risk is largely outweighed by the benefits of information gained from appropriate imaging. X-rays are monitored and regulated to provide the minimum amount of radiation exposure needed to produce the image.Young children and fetuses are more sensitive to the risks of x-rays. Women should tell health care providers if they think they are pregnant.
