【摘要】 目的 :探讨肝脏血池单光发射型计算机断层 (single photonemissioncomputedtomography ,SPECT)诊断肝血管瘤的价值。方法 :对 2 2例临床怀疑为肝脏血管瘤的患者 ,瘤体直径 1.5～ 9.1cm ,行肝实质和血池SPECT ,诊断结果与病理、临床和放射学随访结果进行比较。结果 :2 2例肝占位性病变患者中 18例诊断为肝血管瘤 ,12例经手术后病理检查确诊为肝血管瘤 ,6例经长期临床、放射学和血清肿瘤标志物随访 2～ 3年确定。在排除肝血管瘤的 4例患者中 ,手术后病理诊断 3例肝细胞癌和1例肝囊肿。结论 :肝脏血池SPECT对诊断肝血管瘤具有较高的灵敏度和特异性 ,可以用于鉴别肝脏占位性病变。更多还原

【Abstract】 Objective:To discuss the value of liver blood pool SPECT in diagnosis of hepatic hemangioma.Methods:Twenty-two patients with clinically suspected hepatic hemangioma 1.5-9.1 cm in diameter were examined by hepatic conventional and blood pool SPECT and the results were compared with the histology and radiolgy outcome.Results:Of the 22 cases clinically suspected hepatic hemangioma,18 were diagnosed as hepatic hemangioma by SPECT,which were verified by pathological test (n=12),and clinical,radiological and serum tumor makers follow-up lasting for 2-3 years(n=6).In the other 4 cases,3 were proved hepatogenic cancers and 1 liver cyst by pathology.Conclusions:The liver blood pool SPECT is sensitive and specific in diagnosis of hepatic hemangiomas,and can be used to differentiate benign lesion from malignant lesion.更多还原
