Cerebral black blood MR angiography with the interleaved multi-slab three-dimensional fast spin echo sequence.
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.
