Glucagon-dosed cholescintigraphy.

Cholescintigraphy is applied to the differential diagnosis of surgical and medical icterus. Particularly, in cases in which cholecystography is inapplicable due to iodine anaphylaxis and non visualization by cholecystogram is suspected, the technique is commonly applied for morphological diagnosis. However, functional diagnosis with cholescintigraphy is becoming increasingly important because transitions observable through dynamic study and time-activity curves with ROI are readily available. The author, who has been studying the function of the gallbladder through cholescintigraphy and has been using anticholinergic drug-dosed cholescintigraphy, reports 20 cases of glucagon-dosed cholescintigraphy in this communication.
