摘要
目的 介绍多排螺旋CT三维血管成像技术及其在评价肝硬变门体分流侧支循环方面的临床应用。方法 回顾性总结采用多排螺旋CT增强扫描 ,并通过最大密度投影、表面遮盖显示、容积再现等二维、三维重建技术来显示肝硬变门脉高压侧支循环血管的文献。结果 肝硬变门体分流侧支血管的分布、走行及解剖毗邻关系在多排螺旋CT门静脉血管成像图像上都能得到良好、直观的显示。结论 多排螺旋CT三维血管成像技术有利于血管走行的连续追踪和毗邻关系的清晰显示 。
Objective To introduce the technique of three dimensional portal venography of multi detector row spiral CT and its clinical application in the evaluation of the portosystemic collateral shunts of liver cirrhosis. Methods All relevant literatures were retrospectively reviewed on the application of two dimensional and three dimensional reconstruction techniques such as MIP, SSD, VRT of multi detector row spiral CT to demonstrate the collateral vessels of liver cirrhosis.Results The distribution, pathway and anatomy of portosystemic collateral vessels were well shown by multi detector row spiral CT portal venography. Conclusion Multi detector row spiral CT portal venography provides excellent depiction of the anatomic characteristics of the collateral shunts and enables the continuous tracing of vascular structures, thus it is very helpful in the imaging evaluation of the collateral vessels of liver cirrhosis.
