We studied the application of an iterative image reconstruction technique (ADMM) applied to our high temporal resolution DCE sequence (pCAPR) for prostate imaging, compared to the conventional reconstruction. This was done both subjectively with independent reader ratings of image quality characteristics, and objectively with measurement of quantitative perfusion data from ROI of lesions.
