Medical Imaging Tests

The Washington University Mallinckrodt Institute of Radiology at Barnes-Jewish Hospital draws patients from across the region, state and even nationwide. Our highly skilled radiologists and technologists use the most advanced technology to perform many medical imaging tests not widely available elsewhere.

Radiology Tests We Offer

We perform more than 2,000 types of radiology exams and tests which fall into 9 different areas/categories. Please note: A physician referral is needed to schedule an appointment for any of these services:

  • Computed tomography (CT): Computed tomography is a painless diagnostic procedure that produces detailed, cross-sectional images of your body. We use CT scans to image internal organs, bones, soft tissue and blood vessels. They are the test of choice for detecting tumors and can also reveal life-threatening internal injuries in emergency cases. Read more about CT.
  • Interventional radiology: Interventional radiology procedures are minimally invasive treatments that offer less risk, less pain and shorter recovery time as compared to surgery. We use these procedures in cancer treatments, vascular access procedures and dialysis support. Learn more about interventional radiology.
  • Neuroradiology: Neuroradiology specializes in the diagnosis and treatment of neurological diseases of the brain, spine, and head and neck. Find out more about neuroradiology.
  • Ultrasound: Ultrasound 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 can also reveal movement, such as blood flowing through blood vessels or movement of tendons. Get more information about ultrasound.
  • Magnetic resonance imaging (MRI): Magnetic resonance imaging is a painless diagnostic procedure that uses a powerful magnet, radiofrequencies and an advanced computer to produce images of the body's internal structures. Read more about MRI.
  • Musculoskeletal imaging (MSK): We use MRI and ultrasound technologies to image and diagnose bone and joint conditions. Learn more about MSK.
  • Nuclear medicine: Nuclear medicine exams produce images of the body by using a special camera that detects energy emitting from the radioactive substance, called a radiotracer. We use nuclear scans to diagnose cancers, injuries and infections. They can also show how organs like your heart and lungs are working. Read more about nuclear medicine.
  • Positron emission tomography (PET): PET scans are a type of nuclear medicine exam. The images they produce allow for diagnosis of tumors without the need for surgical biopsies. Find out more about PET scans.
  • X-ray: X-ray is a noninvasive technique that produces pictures of the body's internal structures. For certain X-rays, you may need to ingest a contrast material or barium to help us get a clearer picture of the digestive or urinary tract system. Read more about X-rays.
