To help detect abnormalities and certain symptoms, a contrast agent such as barium is often swallowed at the beginning of the exam. In some cases, you may be given a powder that produces gas inside the stomach, expanding it and making it easier to see during examination.
An upper GI study examines the esophagus, stomach and first part of the small intestine, also known as the duodenum. When coated with a contrast agent (generally barium), the radiologist canassess the anatomy and function of your upper GI tract.
This non-invasive procedure can help diagnose the cause of symptoms such as:
SBFT is a non-invasive fluoroscopic procedure that follows barium through the small bowel, examining size and structure and evaluating for abnormalities
The patient is administered barium contrast liquid and x-rays of the abdomen are taken at regular intervals until the entire small bowel is mapped. SBFT is used in the diagnosis of conditions such as:
Duration: A SBFT exam can take from 1-4 hours, depending on the length of time needed for the barium to pass through the bowel.
A virtual colonoscopy is used to diagnose colon (large bowel) and rectal disease including diverticulosis, inflammatory bowel disease, polyps and cancer. This procedure uses computed tomography (CT) and may require IV contrast in addition to oral contrast. It is a useful alternative to colonoscopy for patients without a known problem or who have a history of bleeding from the colon.
