目的探讨肝细胞癌的磁共振特征及诊断价值。方法对50例肝细胞癌患者进行磁共振扫描,包括横轴位T1WI、脂肪抑制T2WI平扫,横轴位三维动态增强T1WI以及脂肪抑制轴位及冠状位T1WI延迟扫描。结果 50例肝细胞癌患者磁共振扫描显示T2WI均呈稍高或高信号,T1WI呈等、高或低信号;增强扫描43例病灶动脉期明显强化,4例动脉期无明显强化,但门静脉期及延迟期均呈不均匀低信号。结论 MR对肝细胞癌具有极高的诊断价值。
Objective To investigate the magnetic resonance characteristics and diagnostic value of hepatocellular carcinoma. Methods Fifty patients with hepatocellular carcinoma underwent magnetic resonance (MR) scan, including horizontal axis T1WI, fat suppression T2WI, horizontal axis 3D enhanced T1WI, fat suppression axis and coronal T1WI delayed scan. Results The MRI findings of 50 patients with hepatocellular carcinoma showed that T2WI showed slightly higher or higher signal, T1WI showed equal, high or low signal. Forty-three patients with enhanced hepatocellular carcinoma showed enhanced arterial phase and no arterial phase in 4 patients, And the delay period showed uneven low signal. Conclusion MR has a high diagnostic value for hepatocellular carcinoma.
