The rise of MR/US fusion for prostate cancer biopsies
necessitates a true 3D imaging technique. We compared a
T2-weighted 3D variable flip angle turbo spin echo
acquisition versus the standard 2D T2-weighted
acquisition in patients undergoing MR/US fusion biopsy
at 3T. PIRADS scores, image quality scores, and relative
contrast were all equivalent or better in T2w 3D as
compared to T2w 2D. Given the advantages in scan time
and overall voxel size, T2w 3D imaging is a viable
alternative to T2w 2D imaging.
