| 摘 要： | 目的评价CT结构密度成像(CT增强扫描)、功能成像(CT灌注成像、PET-CT代谢显像)对肝细胞癌的病变范围的显像价值。方法 25例肝细胞癌均行CT增强扫描、CT灌注成像及PET-CT检查,根据PET-CT结果分为代谢阴性组和代谢阳性组,计算两组CT增强扫描面积与实际面积差(D1),CT灌注面积与实际面积差(D2),同时计算代谢阳性组PET-CT代谢面积与实际面积差(D3)。结果代谢阴性组10例,D1(2.95±1.41)cm2,D2(0.69±0.41)cm2。D1、D2之间差异有统计学意义(P<0.01)。代谢阳性组15例,D1(6.51±4.76)cm2,D2(1.27±0.89)cm2,D3(0.80±0.55)cm2,D1和D2、D3之间比较差异有统计学意义(P<0.05),而D2和D3比较差异无统计学意义(P>0.05)。结论 CT增强扫描显示肝细胞癌病变范围与实际病变范围存在一定的差距,CT灌注成像、PET-CT代谢显像能够比较准确的反映病变的实际范围,对于临床手术有指导意义。
