Radiologic examination of the gastrointestinal tract

Radiologic Examination of the Gastrointestinal Tract

Radiologic examination of the gastrointestinal (GI) tract is one of the primary procedures used to visualize and evaluate the function of the GI tract. It is used to detect abnormalities or diseases within the gastrointestinal tract such as cancer, ulcers, diverticulosis, and other structural abnormalities. Radiologic examination of the gastrointestinal tract is an important tool for diagnosing and monitoring treatment of many gastrointestinal disorders.

Some of the most common radiologic tests used to evaluate the gastrointestinal tract include:

  • Upper GI series – uses X-ray imaging to visualize the esophagus, stomach and the first part of the small intestine in order to view and evaluate the shape and size of the structures.
  • Lower GI series – uses X-ray imaging to visualize the large intestine in order to detect diseases such as cancers, ulcers, and polyps.
  • Computed Tomography (CT) – uses cross-sectional imaging to detect abnormalities of the digestive organs such as the small intestine, stomach, and colon.
  • Magnetic Resonance Imaging (MRI) – uses magnetism to create detailed images of the gastrointestinal tract to detect tumors, diseases, masses, and inflammation.
  • Barium swallow – uses a contrast material called barium to view the GI tract and diagnose various digestive disorders such as strictures, ulcers, hiatal hernias, and cancers.
  • Endoscopy – uses a flexible camera device that is inserted through the mouth or rectum to identify and diagnose abnormalities within the GI tract.

The purpose of radiologic examination of the gastrointestinal tract is to diagnose, treat, and monitor the progress of diseases and disorders. Depending on the suspected diagnosis, the radiologic examination may include upper GI series, lower GI series, CT scan, MRI, barium swallow, and endoscopy. The results of the examination will then enable physicians to make a diagnosis and provide the necessary treatment plan for the patient.
