央视网消息:近年来,随着医学影像学的发展,我国影像诊断水平已有了很大的提高。据统计,目前80%左右疾病的临床诊断是依靠医学影像辅助检查后作出的,医学影像学检查已成为临床诊断的主要手段之一。

常见影像学检查种类包括B超、X线、CT、磁共振,不同的检查手段各有优势。

X线:简单、经济、方便、快捷,空间分辨率高。

超声:方便、经济。

CT(计算机断层扫描):断层扫描,密度及时间分辨率高,成像速度快。

MR(磁共振):多方位多角度成像,软组织分辨率高,无电离辐射,无需造影剂即可辨别血管等组织结构。

如何选择适合自己的影像学检查手段?平时体检的X光片能筛查肺癌吗?哪些部位的检查首选CT?肝胆胰脾肾首选哪种检查?哪些部位的检查应该首选磁共振?中国医学科学院肿瘤医院影像诊断科唐威医生为您答疑解惑。
