Diagnostic Imaging

If you are injured or if you have symptoms, our doctor may order a diagnostic imaging test. This may be a magnetic resonance imaging (MRI) test, x-ray, ultrasound or computed tomography (CT) scan. These tests are valuable to your doctor so they can make a diagnosis.

PeaceHealth offers advanced technology in diagnostic imaging. We put your safety and comfort first with low-dose radiation machines combined with the expertise needed to capture images and avoid repeat scans. Once the tests are done, results are read by an expert radiologist and shared with your doctor to help you get on the road to recovery.

Care when you need it most

Whether you need an imaging test day or night, our caregivers and radiologists are here to serve you. Caregivers will complete your exam or procedure and send the images to the radiologists for interpretation so they can make a diagnosis to help begin the treatment process.

Treatments Provided

CT (Computed Tomography)

Computed Tomography (CT) scanners deliver a series of cross-sectional views of bones and soft tissues, allowing PeaceHealth to assist your physician with diagnoses. These images are known as “slices” and can be compared to slices of bread from a loaf; the thinner the slice, the more detail available. ​

Our highly trained technologists perform CT scans under the guidance of board-certified radiologists. Our new 128-slice CT scanner offers high-resolution images to assist with diagnosis while also offering a reduction in radiation dose.

With this technology—in addition to a four-slice CT scanner in the Cancer Center—we are able to offer convenient, same-day scanning, with no downtime.

MRI (Magnetic Resonance Imaging)

Magnetic Resonance Imaging (MRI) is a non-invasive method of imaging that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. In many cases, MRI exams give different information about structures in the body than can be seen with an x-ray, ultrasound or computed tomography (CT) scan. MRI scans may also show problems that cannot be seen with other imaging methods. 

The area of the body being studied during an MRI is placed inside a special machine that contains a strong magnet. Pictures from an MRI scan are digital images that can be saved and stored on a computer for more study. The images can also be reviewed remotely, such as in a clinic or an operating room. In some cases, contrast material may be used during the MRI scan to show certain structures more clearly. ​

Nuclear medicine imaging

These tests use a small amount of a radioactive substance (tracer) and a camera to look for problems in your thyroid, parathyroid and adrenal glands.

PET/CT (Positron emission tomography)

PET/CT scans are simple, painless and fast. They offer patients and their families life-saving information that helps physicians detect and diagnose diseases early in order to quickly begin treatment.

A PET/CT scan allows physicians to measure the body's abnormal molecular cell activity to detect:

  • Brain disorders, including Alzheimer's disease, Parkinson's disease and epilepsy.
  • Cancer, including breast cancer, lung cancer, colorectal cancer, lymphoma, melanoma and other skin cancers.
  • Heart disease, including coronary artery disease.

PET/CT scanning and molecular imaging provide real life answers to better diagnose illness, guide treatment options, and give patients ultimate control over their critical and vital health care decisions.​


Ultrasound, also known as a sonogram, or ultrasonography, is widely used in medicine for patients of all ages. Ultrasound is a diagnostic procedure that transmits high-frequency sound waves through body tissues. These sound waves are transformed into images of the internal structures of the body.  

Ultrasound is used for both diagnosis and therapeutic procedures. Sonograms are performed to visualize abdominal and pelvic organs as well as tendons, vessels and other areas in the body. Obstetric ultrasound is commonly used during pregnancy. Ultrasound can be used to guide interventional procedures such as biopsies of the liver and kidney or for the drainage of fluid.​

Vascular ultrasound

A test to discover any narrowing, blockages or abnormalities in your veins and arteries. Your doctor may use this test to diagnose peripheral artery disease or deep vein thrombosis.

X-Ray (Radiography)

X-rays are a type of radiation called electromagnetic waves. X-ray imaging creates pictures of the inside of your body. The images show the parts of your body in different shades of black and white. This is because different tissues absorb different amounts of radiation. Calcium in bones absorbs x-rays the most, so bones look white. Fat and other soft tissues absorb less and look gray. Air absorbs the least, so lungs look black.
