利用CT三维软件实现MRA图像后处理

Post-Treatment of MRA Imaging Using CT Three Dimensional Software

目的 :探讨如何利用螺旋CT三维成像软件进行磁共血管成像 (MRA)后处理。材料与方法 :以颅底动脉环 3D TOFMRA图像后处理为例 ,将图像数据经PACS工作站传输至CT机 ,利用其 3D图像处理软件包实施图像后处理。结果 :18例中 ,利用最大密度投影 (MIP)结合仿真内窥镜 (MRVE)与表面遮盖法 (SSD)等后处理 ,共发现病变 12个 ,其中动脉瘤 5例 ,大脑中动脉狭窄或闭塞 3例 ,脑血管畸形 3例 ,烟雾病 1例。结论 :我们用螺旋CT的三维成像软件成功的进行了MRA的图像后处理 (SSD和MRVE) ,丰富了图像处理手段 ,提高了病变检出率。且无需增加投入 ,方法简捷、经济 ,值得推广。

Purpose:To study how to use spinal CT three dimensionally imaging software to do post-treatment of magnetic resonance angiography.Materials and Methods:Take to post-treatment of MRA of circle of Willis as an example:transport image date to CT through PACS workstation,and use its 3D imaging treating software to do post-treatment.Results:Of 18 cases ,by using MIP combined with MRVE,SSD and other post-treatment,12 were found to have pathologic changes:5 cases of cerebral arterial,3 cases of cerebral artery narrowing,3 cases of AVM,and 1 cases of moya-moya disease.Conclusion:We successfully used spine CT 3D imaging software to do MRA image post-treatment(SSD and MRVE),enriched image treatment method,improved positive detection rate,without increating expenses the method is simple,economical and deserved further application.
