About the Exam

What is a CT scan?

A CT scan (computed tomography) uses X-rays and computer processing to create detailed cross-sectional images of bones, blood vessels, and soft tissues. CT is fast, widely available, and often the first imaging study ordered in the emergency department for trauma, stroke, abdominal pain, and acute illness.

Key advantages

  • Extremely fast — scan times measured in seconds
  • Excellent detail of bone, lung, and vascular anatomy
  • Workhorse modality for trauma, oncology, and emergency care
  • Low dose lung screening
Common Indications

Why your doctor may order a CT

  • Evaluating trauma and internal injuries
  • Diagnosing causes of abdominal or pelvic pain
  • Detecting tumors and monitoring cancer treatment
  • Investigating chest pain, pulmonary embolism, or aortic conditions
  • Pre-surgical planning and image-guided biopsies
  • Low dose lung screening for lung cancer

How to prepare

  • Tell your provider if you have a history of contrast allergy, kidney disease, or are taking metformin.
  • Wear comfortable clothing without metal zippers or buttons in the scan area.

Important Information

If you are or may be pregnant, tell the technologist before your scan. CT uses ionizing radiation and may need to be substituted with another modality.
