核素肝血池显像鉴别肝良恶性占位性病变的临床价值

Radionuclide Hepatic Blood Pool Imaging for Differential Diagnosis Between Benign and Malignant Liver Space Occupying Lesions

采用￣（９９ｍ）Ｔｃ－ＲＢＣ肝血池显像定性诊断肝脏占位性病变３４４例，对其临床价值进行了分析，结果表明，在鉴别肝脏良恶性占位性病变方面与同时检查的Ｂ超（３００例）、ＣＴ（２６１例）和ＭＲＩ（３８例）进行了比较。结果表明，在鉴别被￣（９９）ｍＴｃ－植酸钠肝显像发现的肝脏良恶性占位性病变方面肝血池显像的准确率高达９６．２％。作者提出，核素肝血池显像对肝脏占位性病变定性诊断有重要的临床价值，但认为许多学者推荐的￣（９９ｍ）Ｔｃ－ＲＢＣ肝血流相无助于进一步的鉴别诊断。此外还对核素肝血池显像１３例误诊原因进行了讨论。

Tc-99m-RBC hepatic blood pool scintigraphy was performed on 344 patients with liver space occupyinglesions(SOL)seen in hepatic scintigraphy.The diagnostic value of blood pool scintigraphy were analysed and compared with″B″ultrasonography(300 cases), CT(26 1 cases)and M RI(38 cases).The accuracy of hepatic blood pool imaging in differentiation between benign and malignancy of SOL detected byTc-99m-Phytate liver scintigraphy was 96.2%, and was higher than″B″ultrasonography(51.3%), CT(76.2%),MRI(76.3%).It was concluded that hepatic blood pool imaging is very useful for the differential diagnosis between benign & malignant SOL, Tc-99m-R BC flow phase imaging recommended for further differential diagnosis was considered as noncontributory The cause of mistaken diagnosis has also been discussed.
