A case of a 78-year-old man with delayed visualization of the gallbladder during in vivo labeling for 99mTc-red blood cell scintigraphy for gastrointestinal bleeding is reported. The patient had several episodes of renal failure, melena, anemia, blood transfusion, and hemodialysis. The mechanism of this unusual phenomenon is not clear; however, excess binding of heme and 99mTc-pertechnetate caused by autohemolysis and oliguria are suggested to be the main factor in this phenomenon.
报告了一例78岁男性患者，在用于胃肠道出血的99mTc红细胞闪烁扫描活体标记过程中胆囊显影延迟。该患者有多次肾衰竭、黑便、贫血、输血及血液透析病史。这种异常现象的机制尚不清楚；然而，自身溶血和少尿导致的血红素与高锝酸盐的过度结合被认为是这一现象的主要因素。
