To overcome the disadvantages of conventional three-dimensional time-of-flight MR angiography (3D-TOF), such as saturation or intravoxel dephasing, black blood MR angiography (BB-MRA) using an interleaved multi-slab 3D fast spin echo sequence was developed and evaluated clinically. In major branches, the contrast-to-noise ratio of the flow was not as good as 3D-TOF in BB-MRA. However, in-plane slow flow and large aneurysm were visualized better on BB-MRA than on 3D-TOF. Furthermore, BB-MRA could provide wider coverage than 3D-TOF. BB-MRA using interleaved multi-slab 3D fast spin echo is now feasible and complementary to 3D-TOF.
为克服传统三维时间飞跃磁共振血管造影（3D - TOF）的缺点，如饱和或体素内失相，使用交错多层面三维快速自旋回波序列的黑血磁共振血管造影（BB - MRA）得以开发并进行了临床评估。在主要分支中，BB - MRA中血流的对比噪声比不如3D - TOF。然而，在平面内慢血流和大动脉瘤在BB - MRA上比在3D - TOF上显示得更好。此外，BB - MRA比3D - TOF能提供更宽的覆盖范围。使用交错多层面三维快速自旋回波的BB - MRA目前是可行的，并且是3D - TOF的补充。
