目的:探讨多层螺旋CT检查在肝细胞癌诊断中的价值。方法:对42例经手术和病理证实的肝细胞癌(HCC)行多层螺旋CT检查、三期动态扫描和3D重建并进行分析。结果:42例HCC中,肝左叶17例,肝右叶19例,左右叶多发6例,平扫呈略低密度或等密度影,动脉期表现为低密度的病灶增强而成为高密度,门脉期逐渐下降成为等密度,当肝组织增强达高峰时,病灶成为相对低密度影,达延迟期后,正常肝实质密度下降,可形成第二次等密度期或病灶持续表现为低密度。结论:多层螺旋CT对肝细胞癌的检出和定性准确率的提高有重要价值。
Objective: To investigate the value of multi-slice spiral CT in the diagnosis of hepatocellular carcinoma. Methods: Totally 42 cases of hepatocellular carcinoma (HCC) confirmed by operation and pathology were examined by multi-slice spiral CT, three-phase dynamic scanning and 3D reconstruction. Results: In 42 cases of HCC, there were 17 cases of left hepatic lobe, 19 cases of right lobe and 6 cases of left and right lobes. The lesion showed slightly low density or isodense, while the low phase of arterial phase showed high density, Portal venous phase decreased to equal density, when the liver tissue up to the peak, the lesion becomes a relatively low density, up to the delay period, the normal liver parenchyma density decreased, the formation of the second isodense or lesions continued to show low density . Conclusion: MSCT is of great value in detection of hepatocellular carcinoma and improvement of qualitative accuracy.
