An 18-year-old male was evaluated for recurrent attacks of right abdominal pain and intermittent jaundice caused by hydatid cysts of the liver. The case illustrates the value of dynamic functional information provided by Tc-99m-HIDA imaging over noninvasive modalities that demonstrate structural changes, such as ultrasound, computed tomography, and tin colloid liver imaging.

Technetium-99m mercaptoacetyltriglycine (99Tcm-MAG3) was evaluated for the detection and localization of the site of gastrointestinal bleeding in a sheep model. Radioactivity was detected in both the stomach and lower abdomen. However, 99Tcm-MAG3 is partially excreted by the liver and in the bile.

Acute pancreatitis is a serious surgical problem with a high incidence of mortality. Both ultrasound and X-ray CT have problems in identifying the extent and severity of the disease and the response to therapy. 67Ga-citrate has been used in 21 patients with clinically diagnosed acute pancreatitis: 9 patients had X-ray CT and 15 had US examination.

Four Tc-99 radiopharmaceuticals, Tc-99m sulphur colloid, Tc-99m red blood cells (RBCs), Tc-99m mercaptoacetyltriglycine (MAG3), and Tc-99m DTPA, were studied in an experimental animal model for detection and localization of gastrointestinal (GI) bleeding site in both the upper and lower abdomen. With Tc-99m sulphur colloid and Tc-99m RBCs, it was possible to detect and localize the GI bleeding site in the lower abdomen. With Tc-99m MAG3, it was possible to visualize the bleeding site in both the upper and lower abdomen.
