To investigate the role of SPECT/CT in the diagnosis of hepatic hemangiomas whose anatomical positions are not ideal, situated adjacent to the heart, the inferior cava, hepatic vessels or abdominal aorta, etc.
The hepatic perfusion, blood pool, and fusion imaging were carried out using SPECT/CT in 54 patients, who were suspected for hepatic hemangiomas. When the anatomical positions were not ideal, the diagnosis was difficult by SPECT only. So the information of computed tomography (CT) was applied to help in diagnosing. The results were recorded as hemangiomas or not.
Of the 54 patients, 31 patients were diagnosed as suffering from hepatic hemangiomas. The anatomical positions of eight patients' hepatic hemangiomas (25.81%) were not ideal. Among these lesions of the eight patients, three patients' hepatic lesions were located near to the abdominal aorta, one to the heart, and four to the inferior cava. In addition, six abnormal radioactivity accumulation regions, adjacent to the heart and inferior cava, with the help of CT, were confirmed to be the imaging of inferior cava other than hepatic hemangiomas.
When the anatomical positions of hepatic hemangiomas are not good enough for diagnosis, the fusion imaging of SPECT/CT is a simple and efficient method for differential diagnosis.
探讨单光子发射计算机断层扫描/计算机断层扫描（SPECT/CT）在诊断解剖位置不理想、位于心脏、下腔静脉、肝血管或腹主动脉等附近的肝血管瘤中的作用。
对54例疑似肝血管瘤的患者进行SPECT/CT肝脏灌注、血池及融合成像检查。当解剖位置不理想时，仅通过SPECT诊断困难，因此应用计算机断层扫描（CT）信息辅助诊断。结果记录为是否为血管瘤。
54例患者中，31例被诊断为肝血管瘤。8例（25.81%）患者的肝血管瘤解剖位置不理想。在这8例患者的病变中，3例肝脏病变位于腹主动脉附近，1例位于心脏附近，4例位于下腔静脉附近。此外，借助CT，6个与心脏和下腔静脉相邻的异常放射性聚集区被证实为下腔静脉影像而非肝血管瘤。
当肝血管瘤的解剖位置不利于诊断时，SPECT/CT融合成像是一种简单有效的鉴别诊断方法。
