Scintigraphic diagnosis of a liver hemangioma may be difficult when its size approaches the spatial resolution of a gamma camera, and it may not be visualized on a Tc-99m tin-colloid liver SPECT study. The contribution of Tc-99m labeled RBC scintigraphy is shown in a patient with a liver hemangioma discovered during laparoscopic cholecystectomy for chronic cholecystitis. Despite negative CT, US, and Tc-99m tin-colloid SPECT of the liver, Tc-99m labeled RBC SPECT disclosed a focus of increased activity consistent with the hemangioma.
当肝血管瘤的大小接近γ相机的空间分辨率时，其闪烁扫描诊断可能会很困难，并且在锝-99m锡胶体肝脏单光子发射计算机断层扫描（SPECT）研究中可能无法显影。在一名因慢性胆囊炎行腹腔镜胆囊切除术时发现肝血管瘤的患者中，显示了锝-99m标记红细胞闪烁扫描的作用。尽管肝脏的CT、超声和锝-99m锡胶体SPECT检查结果均为阴性，但锝-99m标记红细胞SPECT显示出一个与血管瘤一致的活性增加灶。
