Diffusion Tensor MR Tractography Effective as Quantitative Tool, Treatment Marker Response

Twenty-two patients with elevated prostate-specific antigen and biopsy-proven prostate carcinoma who underwent MRI of the prostate at 1.5 T with endorectal coil were divided into two groups: those who were treated with androgen deprivation, radiation therapy, or both, and a Gleason-matched control group who had not received such therapy.

“Diffusion t ensor MR tractography may function as a novel quantitative tool and marker of treatment response,” said study coauthor Jennifer W. Uyeda, MD, Brigham and Women’s Hospital. “For example, absence of rise in tract density after therapy and persistent or wider gradient can signify poor response.”

The study was presented at the ARRS 2015 Annual Meeting in Toronto.
