摘要 目的对16层螺旋CT与1.5T MRI扫描法诊断小肝癌的效果差异进行对比分析。方法对回顾性病理分析和临床随访的64例患者分别进行16层螺旋CT与MRI平扫及增强扫描检查,并依据检查手段分为CT组(32例)和MRI组(32例),影像检查结果和术后病理结果为对比依据。结果检查CT组32例41个病灶,MRI组32例38个病灶,小肝癌病灶检出率CT与MRI平扫分别为75.0%和93.4%,差异有显著性(P<0.01),增强扫描分别达到了97.2%和98.3%,MRI组略高,差异无显著性(P>0.05)。结论 MRI平扫对小肝癌的检出率高于CT平扫,增强扫描可提高两者检出率,且增强CT和MRI扫描可以更清楚显示小肝癌的血供特点,优于平扫。CT与MRI增强扫描对小肝癌的检出两者差异无显著性,可根据患者情况选择合适的增强扫描方法。
