TORONTO —Preliminary results of a study of patients with prostate cancer show that MR tractography may be a reliable quantitative imaging biomarker to assess prostate cancer treatment response to androgen deprivation and radiation therapy, according to a team of researchers at Brigham and Women's Hospital and Massachusetts General Hospital in Boston. Quantitative evaluation shows higher tract densities after androgen deprivation and radiation therapy, reflecting gland shrinkage and subsequent fibrosis.
