Active surveillance is regarded as an option to reduce overtreatment in patients with organ-confined low-risk prostate cancer. Transrectal ultrasound-guided biopsy is currently the only method for disease monitoring but has some disadvantages due to its invasive nature and underestimation of tumor dedifferentiation. Multiparametric MRI, on the other hand, can provide quantitative parameters of tissue function that may help to assess tumor aggressiveness. This work evaluates the predictive value of combined DWI and MR spectroscopic parameters to discriminate indolent from aggressive carcinoma.
