摘要
螺旋CT扫描通过快速连续扫描方式立体地采集数据,在肾脏应用方面,与常规CT比较,具有以下特点:①明显缩短检查时间,可进行肾脏多期扫描;②原始立体数据获得后,可进行任意层面、任意间隔及任意层面重叠程度的图像重建;③后处理功能丰富,可获得高质量的多平面重建图象,三维图象,CT血管造影及CT防真内窥镜等图像。螺旋CT克服了传统CT的一些不足,具有更高的临床应用价值,更广的临床应用范围及应用前景.
Spiral CT can acquire the volumetric data in one continuous scan.Compared with renal routine CT imaging, it has some advantages(1) reduced time of examination and acquired multiphasic scaning images : ② retrospectively reconstructed at arbitrary location,space,overlapping sections:③obtained vivid multiplanar. 3D. CTA and CTE images.
