The aim of this study was to speed up the turbo spin echo (TSE) sequence for prostate MRI by undersampling the k-space, while aiming to retain PSNR/SSIM. We conducted undersampling retrospectively by omitting echo-trains in the TSE sequence based on the proximity of the echoes (within the echo-trains) to the centre of the K-space. The proposed method speeds up the TSE acquisition time by 20%, while retaining the PSNR/SSIM for a kiwi phantom. Optimizing an undersampling pattern for prostate therefore can lead to a substantial decrease in the total scan time.
