Recently, tissue-specific prescribed signal evolutions,
achieved by variable refocusing RF-pulse flip angles
(tissue-specific VRFA), have been used to decrease
blurring and obtain better contrast for turbo spin-echo
imaging. Our aim was to assess the impact of
tissue-specific VRFA sequence on 3D T2W-TSE image
quality of prostate at 3T by comparing to conventional
3D and 2D sequence.
