Accelerated 3D T₂ w-imaging of the prostate with 1-millimeter isotropic resolution in less than 3 minutes.

ABSTRACT:

Purpose

To achieve 3D T₂ w imaging of the prostate with 1-mm isotropic resolution in less than 3 min.

Methods

We devised and implemented a 3D T₂ -prepared multishot balanced steady state free precession (T₂ prep-bSSFP) acquisition sequence with a variable density undersampled trajectory combined with a total variation regularized iterative SENSE (TV-SENSE) reconstruction. Prospectively undersampled images of the prostate (acceleration factor R = 3) were acquired in 11 healthy subjects in an institutional review board-approved study. Image quality metrics (subjective signal-to-noise ratio, contrast, sharpness, and overall prostate image quality) were evaluated by 2 radiologists. Scores of the proposed accelerated sequence were compared using t
