RESUMO
(Purpose) We created an image reconstructing multiparametric MRI system called VIVID (Visualization of Various Integration with Diffusion) and examined the efficacy of VIVID in detecting prostate cancer. (Methods and materials) The subjects were 80 patients who underwent one target biopsy with reference to MRI images in addition to 8-20 biopsies. (Results) The significant cancer detection rate was 61%, the significant cancer detection rate of PI-RADS 4 or 5 was 55%, and the significant cancer detection rate of VIVID score 4 or 5 was 55%. Three cases with PI-RADS 4 at TZ lesion with positive T2WI only were evaluated as having VIVID scores 1 or 2. Cancer was not detected with target biopsy from the site. (Conclusion) Our finding suggest that VIVID correctly excludes TZ lesions with only T2WI positively in multiparametric MRI.
