     【摘要】目的:探讨99TcmSC和99TcmEHIDA联合显像诊断肝细胞腺瘤(HA)的显像特点及临床价值。方法:8例HA行核素显像,首次为99TcmSC显像,隔日行99TcmEHIDA显像,应用兴趣区技术分别计算30min、1h和2h的病灶/正常肝组织(L/N)比值。同时与CT和MRI检查结果比较。结果:全部病人皆行外科手术治疗并经病理学确诊。核素显像诊断HA准确率100%(8/8),高于CT和MRI检查准确率(4/7,5/6)。核素显像30min、1h和2h的L/N比值差异有统计学意义。结论:核素显像是诊断HA可靠而有效的方法,尤其当CT和MRI缺乏典型表现时,有其独到的应用价值。

    【ABSTRACT】Objective:To evaluate the accuracy and characteristics of combined use of 99Tcmsulfur colloid (SC)and 99Tcmdiethyliminodiacetic acid (EHIDA)imaging on the diagnosis of hepatic adenoma (HA).Methods:8 patients with HA were involved in this study.All of them were studied by nuclear medicine (NM)with dualradiopharmaceuticals.The 99TcmSC imaging was perfomed first ,then the 99TcmEHIDA imaging two days later,and the ratios between lesions and normal liver tissue(L/N)were calculated in terms of different counts within the same size regions of interest (ROI) in different phases(30min,1h and 2h respectively).Some of the cases were also analysed by CT and/or MRI within one week before the operations.Results:All of the cases were submitted to surgical treatment and confirmed diagnosis of HA by pathology. For HA, scintigrahy presented a accuracy of 100%(8/8),which was higher than that of CT and MRI comparatively.For 99TcmEHIDA imaging,there were significant differences in L/N ratios among different phases(30min,1h and 2h).Conclusion:The results show that radionuclide imaging proved to be a safe,invasive and effcetive method on the diagnosis and differential diagnosis of HA,especially ,when CT and/or MRI findings are not typical. ......
