MR protocol of multiparametric MRI of the prostate who underwent contrast-enhanced US guided biopsy.

T1WI and T2WI = T1- and T2-weighted images, TR = repetition time, TE = echo time, msec = millisecond, FOV = field of view, DWI = diffusion weighted images, ADC = apparent diffusion coefficient, DCE = dynamic contrast enhanced, Ktrans = transfer constant.* The fitting of concentration versus time curves was performed based on theoretical models by Tofts. Perfusion-related parameters including Ktrans were derived by the curves [18]. We used commercial software (Tissue4D; Siemens healthcare, Erlangen, Germany) in the construction of perfusion map images.MR protocol of multiparametric MRI of the prostate who underwent contrast-enhanced US guided biopsy.
