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.
