AB  - PURPOSE: The aims of this study were to establish a 5-minute magnetic resonance
      (MR) screening protocol for prostate cancer in men before biopsy and to evaluate 
      effects on Prostate Imaging Reporting and Data System (PI-RADS) V2 scoring in
      comparison to a conventional, fully diagnostic multiparametric MR imaging (mpMRI)
      approach. MATERIALS AND METHODS: Fifty-two patients with elevated
      prostate-specific antigen levels and without prior biopsy were prospectively
      included in this institutional review board-approved study. In all patients, an
      mpMRI protocol according to the PI-RADS recommendations was acquired on a 3 T MRI
      system. In addition, an accelerated diffusion-weighted imaging sequence was
      acquired using simultaneous multislice technique (DW-EPISMS). Two readers
      independently evaluated the images for the presence/absence of prostate cancer
      according to the PI-RADS criteria and for additional findings. In a first reading
      session, only the screening protocol consisting of axial T2-weighted and
      DW-EPISMS images was made available. In a subsequent reading session, the mpMRI
      protocol was assessed blinded to the results of the first reading, serving as
      reference standard. RESULTS: Both readers successfully established a final
      diagnosis according to the PI-RADS criteria in the screening and mpMRI protocol. 
      Mean lesion size was 1.2 cm in the screening and 1.4 cm in the mpMRI protocol (P 
      = 0.4) with 35% (18/52) of PI-RADS IV/V lesions. Diagnostic performance of the
      screening protocol was excellent with a sensitivity and specificity of 100% for
      both readers with no significant differences in comparison to the mpMRI standard 
      (P = 1.0). In 3 patients, suspicious lymph nodes were reported as additional
      finding, which were equally detectable in the screening and mpMRI protocol.
      CONCLUSIONS: A 5-minute MR screening protocol for prostate cancer in men with
      elevated prostate-specific antigen levels before biopsy is applicable for
      clinical routine with similar diagnostic performance as the full diagnostic mpMRI
