Decision analysis model comparing cost of multiparametric magnetic resonance imaging vs. repeat biopsy for detection of prostate cancer in men with prior negative findings on biopsy

The use of MP-MRI to select patients for repeat biopsy reduced the number of biopsies needed by 73% but resulted in a few cancers being missed at lower cost when compared with the TRUS arm. Further studies are required to determine whether cancers missed represent clinically significant tumors.
