Twenty-seven patients with histologically confirmed prostate cancer underwent two repeated 3T MRI examinations consisting of T _RAFF , T ₁ and T ₂ mapping. Rotating frame imaging (RAFF, and continuous wave T ₁ ) of PCa was feasible using clinical 3T MRI scanner and demonstrated robust repeatability. Both T _RAFF and T ₁ of PCa differed significantly from similar value of normal peripheral zone.
