摘要 目的评价多排螺旋CT扫描在小肾癌诊断中的临床意义。方法回顾性分析我院2004年3月~2007年5月收治的31例经手术或活检证实的小肾癌(≤3cm)的螺旋CT资料。结果31例小肾癌病灶中平扫低密度(低于同层面肾皮质密度)23例,等密度3例,高密度5例。增强扫描动脉期(皮质期)23例呈明显全瘤性均匀强化,其中幅度等于或稍高于肾皮质13例,10例稍低于肾皮质,12例呈不均匀强化,3例呈明显边缘强化,1例强化不明显。静脉期(皮髓质分界期)病灶强化区强化程度稍低于肾皮质。髓质期及肾盂期强化迅速减退,呈"快进快退"改变。结论螺旋CT扫描在小肾癌的诊断中较常规CT有明显优越性,多数小肾癌动脉期强化明显,实质期强化迅速减退,肾盂期呈更低密度,呈"快进快退"表现。
