Gallbladder visualization occurred after a Tc-99m red blood cell (RBC) cardiac gated blood pool scan. To date, seven cases of gallbladder visualization after the intravenous injection of Tc-99m RBCs have been reported. In the previous six patients the gallbladder was visualized incidentally during a search for gastrointestinal (GI) bleeding. All of the patients were anemic, six of seven had chronic renal failure, and five of seven had received multiple blood transfusions. When interpreting GI bleeding scans in patients with anemia and renal failure, awareness of the possibility of gallbladder visualization in the delayed images is important to avoid false-positive results.
在进行锝-99m红细胞（RBC）门控心血池扫描后出现了胆囊显影。迄今为止，已有7例静脉注射锝-99m红细胞后胆囊显影的病例报道。在前6例患者中，胆囊是在寻找胃肠道（GI）出血的过程中偶然显影的。所有患者均贫血，7例中有6例患有慢性肾衰竭，7例中有5例接受过多次输血。在解读贫血和肾衰竭患者的胃肠道出血扫描结果时，意识到延迟图像中胆囊显影的可能性对于避免假阳性结果很重要。
