通过对Ｂ超、彩色多普勒超声、ＣＴ这几种非侵入性影像学方法诊断４２例肝癌和２０例良性肝占位病变作用的分析，探讨这些影像方法对肝癌定性、定量、定位诊断能力，结果是联合几种影像方法诊断原发性肝癌的敏感性、特异性、准确性达９７．６％。但对一些部位的小病灶，如近膈顶区的病灶有遗漏，在定量诊断方面也有一些限度。作者认为，对一些肝脏小病灶的诊断和鉴别诊断，及部分病例治疗方案的制定，仍需应用血管造影和／或血管造影ＣＴ、碘油ＣＴ等有一定创伤的影像诊断技术，以进一步提高诊断水平。
By analyzing the effects of B-ultrasonography, color Doppler ultrasonography, and CT-based non-invasive imaging methods on the diagnosis of 42 cases of hepatocellular carcinoma and 20 cases of benign hepatic lesions, the qualitative, quantitative, and localization diagnostic capabilities of these imaging methods for hepatocellular carcinoma were explored. As a result, the sensitivity, specificity, and accuracy of the combination of several imaging methods for the diagnosis of primary liver cancer were 97.6%. However, there are some limitations in the quantitative diagnosis of small lesions in some areas, such as lesions in the near dome area. The authors believe that the diagnosis and differential diagnosis of some small liver lesions and the formulation of treatment plans for some cases still require the use of angiography and/or angiographic CT, lipiodol CT and other imaging diagnostic techniques to further improve the diagnosis.
