With the advent of multislice CT, temporal and spatial resolution has been dramatically improved, enabling multi-phase dynamic CT of the abdomen with very thin slices. The image quality of multiplanar reconstruction (MPR) and CT angiography (CTA) has been markedly improved. These high-quality dynamic CT, MPR, and CTA images are an advantage of multislice CT of the abdomen. The CT protocol is very important in obtaining such high-quality images, and knowledge of the relation between the contrast medium and enhancement of each organ is essential. In this article, we present our multislice CT protocol for the abdomen as well as the results of our investigation using time-density-curve analysis. The clinical usefulness of MPR images and CTA of the abdomen are also discussed.
随着多层螺旋CT的出现,时间和空间分辨率得到了显著提高,能够以非常薄的层厚进行腹部多期动态CT扫描。多平面重建(MPR)和CT血管造影(CTA)的图像质量也有了显著改善。这些高质量的动态CT、MPR和CTA图像是腹部多层螺旋CT的优势所在。CT扫描方案对于获得此类高质量图像非常重要,了解造影剂与各器官强化之间的关系至关重要。在本文中,我们介绍了我们的腹部多层螺旋CT扫描方案以及使用时间-密度曲线分析的研究结果。还讨论了腹部MPR图像和CTA的临床应用价值。
