So, you need to get an imaging procedure, but you're not sure why or what physicians will be able to find based on your results? Learn more about the various tests available with St. Mark's Imaging here:


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

The ultrasound imaging technique is most widely recognized as used during pregnancy, where it is used to visualize the embryo of fetus in a mother's uterus to determine a variety of information regarding the health of the mother and fetus, progress of the pregnancy, and more information of the baby (i.e., gender). 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.

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 can therefore be manipulated more, allowing radiologists a clearer view of the results.

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 are used to obtain 2-D images or 3-D volumes. The MRI technique provides more detail when examining the soft tissues of the body, which makes it especially useful in imaging procedures for the brain, muscles, heart, and cancers.

Nuclear Medicine Scan

Nuclear Medicine imaging uses small amounts of radioactive material to diagnose and determine the severity of a variety of diseases, including cancers, heart disease, gastrointestinal, endocrine, neurological disorders, and other abnormalities within the body. These procedures can pinpoint molecular activity within the body and, therefore, they offer the potential to identify diseases in their earliest stages, as well as a patient's immediate response to treatment.

CT Scan

CT Scanning, sometimes called CAT Scanning, combines special x-ray equipment with computers to produce multiple images of inside the body, which are used to help physicians 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.


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.
