The imaging services performed at St. Mark’s are obtained and managed by a fully digital environment referred to as PACS (picture archive and communication system). This advanced technology means your radiologist or provider can access and view your digital images and test results from anywhere there is internet access. Often, by the time you get home, your images have already been captured, read and a report has been sent to your referring physician.

Imaging and radiology services in Salt Lake City

St. Mark’s imaging and radiology department offers same-day appointments, fast report-turnaround times, competitive rates and convenient locations.

Our comprehensive imaging and radiology services in Salt Lake City include:


Commonly called sonography or ultrasonography, an ultrasound uses high-frequency sound waves to display moving, 3D images of the inside of the body on a monitor. No radiation is involved with ultrasound imaging procedures.

The ultrasound imaging technique is often used during pregnancy to check the health of the baby. However, ultrasounds are also used for visualizing other parts of the body, like tendons, muscles, joints, vessels and internal organs to look for possible disease or abnormality.

Before your ultrasound

Wear comfortable, loose-fitting clothing for your ultrasound exam. You may be asked to wear a gown and to remove all clothing and jewelry in the area being examined. Other preparation depends upon the type of exam. For some exams, you may be asked not to eat or drink for 12 hours before your appointment, while other exams might require you to drink up to six glasses of water two hours before your appointment.

Digital mammography

Digital mammography is the most advanced breast imaging technology available today. This form of mammography uses digital receptors instead of X-ray film to capture images of breast tissue that are examined by radiologists for things like breast cancer. The images can be viewed on a computer screen and give radiologists a clearer view of the results. For more information on breast care, check out our Women's Diagnostic Center.

Before your mammogram

The American Cancer Society (ACS) recommends discussing any breast problems with your doctor before scheduling a mammogram. The best time to schedule a mammogram is during the week after your period. Do not schedule your mammogram for the week before your period if your breasts are usually tender during this time. Inform your doctor or X-ray technologist if there is any possibility that you are pregnant. The ACS also recommends not wearing deodorant, talcum powder or lotion under your arms or on your breasts on the day of the exam.

Magnetic resonance imaging (MRI)

Magnetic resonance imaging is an imaging technique used to visualize internal structures of the body in detail. In this procedure, you will lay inside a large, powerful magnet—the magnetic field and radio frequency waves obtain 2D images or 3D volumes.

St. Mark’s new MRI device allows for advanced imaging of neurological, body, vascular, cardiovascular and orthopedic conditions. This advanced technology improves image resolution and quality for patients with metal implants and provides non-contrast enhanced vascular imaging.

Before your MRI

You should wear loose-fitting clothing, but know that you may be asked to wear a gown during the exam if needed. Guidelines for eating and drinking before an MRI exam vary by procedure. You may have to receive an injection of contrast material in the bloodstream; the radiologist or X-ray technologist will make sure you have no allergies before performing this injection.

Let the technologist know if you have any metal implants, medical or electrical devices in the body—some of these could interfere with the exam or pose a risk. If you are claustrophobic and have anxiety, you may want to ask your healthcare provider for a prescription for a mild sedative prior to your scheduled exam.

Nuclear medicine imaging

Nuclear medicine imaging uses small amounts of a radioactive substance, called a tracer, to look for problems in the body. An example of a nuclear medicine exam is a PET scan. 

Nuclear medicine tests can diagnose numerous cancers, diseases and conditions in the intestines, heart, brain, tissues, endocrine system and other parts of the body. These procedures can pinpoint molecular activity within the body and, therefore, they offer the potential to identify diseases in their earliest stages.

Before your nuclear medicine exam

You may be asked to wear a gown during the procedure. Inform the technologist if there is any possibility you are pregnant and of any medications you are taking. 

The tracer may be injected, swallowed or inhaled. Your scan may be done right away, or you may need to wait a few hours or days to let the tracer concentrate in the part of the body being studied. You may be scanned multiple times during one day depending on the type of nuclear scan you have. Further instructions vary by the type of nuclear medicine exam.

Computed tomography (CT) scan

A CT scan, sometimes called a CAT scan, combines special X-ray equipment with computers to produce multiple images of inside the body. A CT scan is used to diagnose and treat medical conditions, such as cancers, cardiovascular disease, infectious disease, appendicitis, trauma and musculoskeletal disorders. A CT scan can provide more detail than images obtained from a regular X-ray exam.

We also offer 64-slice /16-slice big bore CT scanning at St. Mark’s. This is a faster procedure that decreases patient exposure to radiation and provides high-quality digital images of any organ and blood vessels in a few seconds.

Before your CT scan
You may be given a gown to wear during the procedure and be asked to remove metal objects that you're wearing like jewelry, eyeglasses, dentures, hairpins, etc. You also may be asked not to eat or drink anything for several hours before your exam. Always inform your doctor of any recent illnesses or medical conditions, or if there is a possibility you are pregnant.


Fluoroscopy is an imaging technique used to obtain real-time moving images of internal structures in the body using a fluoroscope, which typically consists of an X-ray source and a fluorescent screen between which a patient is placed. More advanced technology includes a video camera that allows the images obtained to be recorded and played on a monitor. Fluoroscopy is commonly used for investigations of the gastrointestinal tract, orthopedic surgery, angiography of vessels and more.
