Gastrointestinal lymphomas can occur in nodular, polypoid, cavitary, ulcerative or diffuse infiltrating (submucosal) forms. Barium studies and computed tomography (CT) are the most popular imaging techniques used to diagnose these lymphomas. Barium studies are superior to CT in evaluating mild mucosal and submucosal changes. However, CT is the technique of choice because it provides a complete evaluation of the extent of disease dissemination, recent disease development, therapeutic response, and related complications.

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...
