The gold standard technique for measuring gastric emptying is scintigraphy using radiolabeled test meals. Recently, a standardized radiolabeled solid meal has been proposed and adopted by many centers. There is still a need for alternative meals, and several such meals with demonstrated radiolabel stability have been evaluated in small numbers of subjects. Updated radiation dosimetry associated with these meals has been calculated for adult males and adult females with normal gastrointestinal transit as well as transit abnormalities.

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...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
