Hepatobiliary imaging with the various technetium-labeled IDA compounds is more than 90% sensitive and specific for the diagnosis of acute cholecystitis. Causes of false-positive studies include chronic cholecystitis, cystic-duct obstruction by tumor, prolonged fasting, the nonfasting state, pancreatitis, alcoholism, parenteral hyperalimentation, and severe intercurrent illness. A case of congenital absence of the gallbladder is submitted as another cause of a false-positive scan.
使用各种锝标记的亚氨基二乙酸（IDA）化合物进行肝胆成像对急性胆囊炎诊断的敏感性和特异性超过90%。假阳性检查的原因包括慢性胆囊炎、肿瘤导致的胆囊管梗阻、长期禁食、非禁食状态、胰腺炎、酒精中毒、胃肠外高营养以及严重的并发疾病。现提交一例先天性胆囊缺如的病例作为扫描结果假阳性的另一原因。
