There are many types of imaging tests used to detect breast cancer, including ultrasound, magnetic resonance imaging (MRI), mammography and breast tomosynthesis. Your care team will decide which is right for you and your condition or diagnosis.

This safe, effective imaging test uses X-rays to detect breast cancer. It helps doctors see abnormalities like lumps and allows them to detect cancer even before symptoms develop.

Mammography

Also called 3D mammography, this screening test produces X-ray images of the breasts from multiple angles to create a crystal-clear, 3D reconstruction. If you have dense breast tissue, your doctor might recommend this screening, which makes it easier for doctors to identify any problem areas.

Breast tomosynthesis

MRI is a test that uses large magnets and a computer to create detailed images of structures inside your body. It does not use radiation. Breast MRI is most often used to check for breast cancer. It's is often done with contrast dye injected into a vein in the arm before or during the procedure to help create clearer images.

Breast MRI


We offer low-dose CT scans, which can detect lung cancer at an early stage, before it's likely to have spread. Low-dose CTs produce detailed images of your lungs without as much radiation exposure as a standard CT scan, allowing high-risk patients to receive regular screenings.

A number of screenings are now available to help identify colon cancer. These include flexible sigmoidoscopy, colonoscopy, virtual colonoscopy and double-contrast barium enema. Our radiologists work closely with physicians who specialize in diagnosing and managing colorectal issues, and our care team strives to make your experience as comfortable as possible.

Magnetic resonance imaging (MRI) is a noninvasive, painless medical test that uses a magnetic field, radio frequency pulses and a computer to produces detailed images of internal body structures like organs, soft tissues and bones.

Below are links to a variety of imaging exams utilized by UW Medicine's Radiology Services. Each exam covers a range of procedures. Click on any of the following links to learn more about a given exam or procedure.

​​​​Bone densitometry is used to assess your bone health and fracture risk. This handout explains how the exam works, how to prepare for it, what to expect during the exam and how to get your results.

Bone densitometry (DEXA​)

Interventional Radiology (IR) is one of the most exciting and advanced fields in medicine, but it is also one of the least well known. IR uses the latest in imaging technology to perform minimally invasive procedures throughout the body. Procedures that once required large incisions, general anesthesia, and days or weeks in the hospital can now be done on an outpatient basis with an incision so small that it does not require stitches.

Please select a procedure from the following list:

Interventional radiology (angiography)

CT imaging—sometimes called CAT scanning—is a noninvasive test that helps physicians diagnose and treat medical conditions. CT combines special X-ray equipment with sophisticated computers to produce multiple images or pictures of the inside of the body. These cross-sectional images of the area being studied can then be examined on a computer monitor or printed.

Please choose from the list below to learn more about your CT procedure:

​Computed tomography (CT)​

A mammogram is an imaging test to find breast cancer. It uses X-ray to take images of the breasts. There are two types of mammograms: Screening mammograms are used to find breast cancer in women who do not have breast symptoms or complaints. Diagnostic mammograms are used to look for the cause of a symptom, such as a lump in the breast.

Mam​mography

​Fluoroscopy is an imaging technique that uses X-ray to obtain real-time moving images of the internal structures of a patient through the use of a fluoroscope. A video camera allows the images to be recorded and played on a monitor. Please choose from the list below to learn more about the various fluoroscopy procedures: 

Fluoroscopy

An X-ray (radiology exam) is a medical test that produces images (pictures) of a part of a body. These images help doctors diagnose health conditions. Doctors use bone X-ray to view and assess broken bones, skull fractures and spine injuries. Bone X-ray may also be used to guide orthopedic surgery (surgeries that involve bones, joints, ligaments or muscles), treat sports-related injuries and diagnose advanced forms of bone cancer. 

General radiology

Magnetic resonance imaging (MRI) is a noninvasive medical test that helps physicians diagnose and treat medical conditions. MRI uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures.

​​​​​Positron emission tomography (PET) and computerized tomography (CT) are both standard imaging tools that allow physicians to pinpoint the location of cancer within the body before making treatment recommendations. The highly-sensitive PET scan detects the metabolic signal of actively growing cancer cells in the body and the CT scan provides a detailed picture of the internal anatomy that reveals the location, size and shape of abnormal cancerous growths.

To learn more, please select from the following list of PET-CT procedures:

Positron emission tomography (PET/CT)
Ultrasound


A CT scan—sometimes called a CAT scan—is a noninvasive medical imaging test that combines special X-ray equipment with sophisticated computers to produce multiple cross-sectional pictures of the inside of the body. Our safe, state-of-the-art CT scan equipment uses the lowest possible radiation dose while delivering optimal results.

For this exam, patients are given a small amount of radioactive compound that localizes in specific organs and can be detected by a special camera. Resulting images help doctors evaluate heart, lung and kidney function, the presence of cancer and more. Risks from radiation exposure are considered low.

A positron emission topography (PET) scan is a type of nuclear medicine imaging test used to examine body tissues and organs to identify medical conditions. PET scans are often performed alongside CT scans to increase diagnostic accuracy by combining the results from these two powerful tests.

PET/CT

This type of nuclear medicine imaging produces especially detailed results of organ and tissue structure and function by using a gamma camera that rotates around you. It's most commonly used to diagnose or monitor brain, heart and bone problems. Our SPECT scans are highly effective and present little risk.

SPECT/CT


Most of our imaging procedures have a low risk of side effects from radiation exposure. But we continually work to reduce the radiation dosage of imaging tests while maximizing the benefits of these powerful disease-fighting tools. And each of our patients is closely monitored by a team of on-site physicists.

Also called a bone density test, this exam is most often used to detect osteoporosis (thinning of the bones). The exam is quick and painless and uses two very low-dose X-ray beams.

There are many types of routine radiography used to produce different types of images depending on each patient’s individual clinical needs. X-ray, fluoroscopy and tomosynthesis are common among them.

An X-ray is a simple medical imaging test that produces a one-dimensional image of a part of the body—often the bones or chest—so that doctors can diagnose health conditions. At UW Medicine, we use digital X-rays, which have 70 percent less radiation than film X-rays.

X-ray

During this imaging test, a continuous X-ray beam is passed through a body part and sent to a video monitor. Fluoroscopy allows doctors to closely observe an area of the body in motion, such as the heart, joints, bowels, bones or muscles, in order to evaluate function.
