Modified protocols along with routine of significance are fat saturation sequence, diffusion and ADC sequence; and if vascular lesions were suspected angiography 2D or 3D TOF sequence was required.
We analyzed two sequences: T2 sequence for visualization of cerebral parenchyma; 3D TOF sequence for the assessment of CoW morphology.
Intra-voxel dephasing can be reduced using smaller voxels, shorter TE, and flow compensation.6 TOF sequences with shorter TEs have reduced extent of spatial encoding sequence gradients and are therefore less sensitive to high-order motion that leads to better assessment of stenosis.16 Smith et al.17 proposed that TOF MR angiography with TE of 5.1 ms improved signal intensity recovery compared with TE of 6.5 ms.
