Cholescintigraphic diagnosis of acute cholecystitis requires accurate assessment of gallbladder nonvisualization. Confusion may occur when the gallbladder overlies the duodenal sweep or when labeled bile pools in the duodenum. Gallbladder activity could not be differentiated from duodenal activity in 21 patients. The oral ingestion of 225 ml of water permitted successful differentiation of the gallbladder from the duodenum. In 25 control subjects, it was demonstrated that that volume of water did not have a cholecystokinetic effect.
急性胆囊炎的胆闪烁造影诊断需要准确评估胆囊不显影情况。当胆囊位于十二指肠曲上方或十二指肠内有标记胆汁池时，可能会出现混淆。21例患者的胆囊活动无法与十二指肠活动区分开来。口服225毫升水可成功区分胆囊与十二指肠。在25名对照受试者中，证明该水量没有胆囊运动效应。
