目的分析多排螺旋CT与磁共振成像检测乙肝肝硬化背景小肝癌的临床价值。方法选取乙肝肝硬化背景小肝癌患者70例(84个病灶),根据病灶直径大小将患者分为两组,小肝癌组与微小肝癌组,每组35例。两组均给予多排螺旋CT及磁共振检查。比较两种不同检查方法下病灶检出率、不同时段及序列下病灶检出率。结果两种检测方式下乙肝肝硬化背景小肝癌病灶检出率比较差异未见统计学意义(P>0.05);小肝癌组检出率最高为CT动脉期及序列LAVA,最低为CT平扫,微小肝癌组病灶检出率最高的序列为LAVA动脉期,检出率最低的为CT平扫及LAVA平衡期,其余序列及时段检测中比较差异未见统计学意义(P>0.05)。结论与多排螺旋CT检测相比,磁共振在乙肝肝硬化背景小肝癌中具有较高的病灶检出率,且不同序列的成像为诊断提供了有利依据,值得临床推广。
Objective To analyze the clinical value of multislice spiral CT and magnetic resonance imaging in the detection of small hepatocellular carcinoma with hepatitis B cirrhosis. Methods Seventy patients (84 lesions) with small hepatocellular carcinoma in the background of hepatitis B cirrhosis were selected. The patients were divided into two groups according to the diameter of lesion, the small hepatocellular carcinoma group and the small hepatocellular carcinoma group with 35 cases in each group. Both groups were given multi-slice spiral CT and magnetic resonance imaging. Compare the detection rate of lesions under two different examination methods, the detection rate of lesions under different time and sequence. Results There was no significant difference in the detection rate of small hepatocellular carcinoma among the two detection methods (P> 0.05). The detection rate of small hepatocellular carcinoma was the CT arterial phase and sequence LAVA, the lowest was CT scan, The sequence with the highest detection rate was LAVA arterial phase. The lowest detection rate was CT scan and LAVA balance phase. There were no significant differences among the other sequences and time segments (P> 0.05). Conclusion Compared with multislice spiral CT, MRI has a higher detection rate of lesions in small hepatocellular carcinoma with cirrhosis of the liver, and imaging of different sequences provides a favorable basis for diagnosis and is worthy of clinical promotion.
