About Medical Imaging Exams

Please select an exam from the list below for more information.

MRI scan

CT scan


Ultrasound is a diagnostic procedure that does not use radiation, but uses high frequency sound waves to produce images of the area(s) of concern. Commonly used to see a fetus during pregnancy, ultrasound is also used to look at muscles, tendons, and internal organs. The images are shown in real time, so they reveal movement, such as blood flowing through blood vessels or movement of tendons.

Interventional Radiology (IR)

Interventional radiology procedures are performed by a specialized team lead by an interventional radiologist. IR procedures are image-guided, minimally invasive, targeted treatments that offer less risk, less pain, and less recovery time as compared to surgery. The Interventional Radiology department at Barnes-Jewish Hospital is one of the largest, most comprehensive IR departments in the United States.


Neuroradiology specializes in the diagnosis and treatment of neurological disease of the brain, head and neck, and spine through neuroimaging techniques.

Musculoskeletal (MSK)

Musculoskeletal (MSK) Radiology specializes in diagnosis and treatment of bone and joint medical conditions.

Gastrointestinal and Genitourinary (GI/GU) Exams

GI (gastrointestinal) exams are x-rays of the upper and lower digestive system. The upper GI looks at the esophagus and stomach. The small bowel series looks at the small intestine. The barium enema looks at the colon. GU (Genitourinary) exams are x-rays of the urinary tract system (kidney, ureter and bladder).

Nuclear Medicine Exams

Nuclear medicine exams are diagnostic exams that produce images of the body by using a special camera that detects energy emitting from the radioactive substance, called a radiotracer. Nuclear scans help doctors diagnose many conditions, including cancers, injuries, and infections. They can also show how organs like your heart and lungs are working.


Positron Emission Tomography/Computed Tomography or PET/CT scans are non-invasive diagnostic exams that produce images of the body. PET/CT scans involve a special camera that detects energy emitting from the radioactive substance, called a radiotracer.


X-rays are painless, noninvasive, quick medical tests that produce images of your body to help physicians in diagnosis and treatment of medical conditions. X-rays are a type of radiation made up of electromagnetic waves. X-rays pass through the body and record an image on a special digital recording plate. These digital files can be stored electronically.
