Enhanced z-axis coverage with thin overlapping slices in breath-hold acquisitions with multidetector CT (MDCT) has considerably enhanced the quality of multiplanar 3D reconstruction. This pictorial essay describes the improvements in 3D reconstruction and technical aspects of 3D reconstruction and rendering techniques available for abdominal imaging. Clinical applications of 3D imaging in abdomen including liver, pancreaticobiliary system, urinary and gastrointestinal tracts and imaging before and after transplantation are discussed. In addition, this article briefly discusses the disadvantages of thin-slice acquisitions including increasing numbers of transverse images, which must be reviewed by the radiologist.
在多排螺旋CT(MDCT)屏气采集中,采用薄的重叠层厚进行z轴覆盖增强,显著提高了多平面3D重建的质量。这篇图文并茂的文章描述了3D重建的改进以及腹部成像可用的3D重建和渲染技术的技术方面。讨论了3D成像在腹部的临床应用,包括肝脏、胰胆系统、泌尿系统和胃肠道以及移植前后的成像。此外,本文简要讨论了薄层采集的缺点,包括增加了横向图像的数量,放射科医生必须对这些图像进行审查。
