微小肝细胞结节性病变CTHA及CTAP的诊断价值

The Value of CTHA and CTAP in the Diagnosis of Small Hepatocellular Nodular Lesions

目的:分析肝细胞结节性病变在CTHA 和CTAP 上的不同表现,评价其对早期肝细胞癌的诊断价值。方法:对32例肝细胞结节性病变患者行CTHA、CTAP和组织学检查。结果:18 个中、低分化型肝细胞癌结节均显示为CTHA高密度、CTAP低密度;7个再生性结节和腺瘤样增生中有4个结节CTHA和CTAP均呈等密度;其余21 个结节根据恶性程度的不同,显示为由高分化到低分化不同类型的CTHA和CTAP表现。结论:CTHA和CTAP可提高早期肝细胞癌的检出率,且可用以推测肝细胞结节性病变的恶性程度,指导临床治疗。

Objective:To investigate imaging features of small hepatocellular nodular lesions using CTHA,CTAP and assess the value of early detection of hepatocellular carcinoma (HCC).Methods:32 cases of 43 small hepatocellular nodular lesions with less than 20mm were performed CTHA,CTAP,and US or MRI.The diagnosis of all cases was proved pathologically.Results:All 18 moderately and poorly differentiated HCC showed high density on CTHA and low density on CTAP.4 of 7 nodules with large regenerative nodule and adenomatous hyperplasia showed isodensity both on CTHA and CTAP.In the 21 remaining nodules,the finding of each nodule was different relating to the mode of hepatocellular differentiation.Conclusion:CTHA and CTAP is very useful for the evaluation and differentiation of small hepatocellular nodular lesions,and can increase the number of detectable HCC.
