    MRI-targeted biopsy: is systematic biopsy obsolete?
    Can J Urol 2017 Aug;24(4):8876-8882
    Urologic Oncology Branch, National Cancer Institute, National Institutes of Health, Bethesda, Maryland, USA.
    Introduction: Although prostate cancer is the most common non-cutaneous cancer in men, it is traditionally diagnosed with a non-targeted, systematic transrectal ultrasound prostate biopsy (TRUS-Bx). This technique has been demonstrated to both under-detect clinically significant (CS) cancer and over-detect clinically insignificant cancer, and performs poorly in patients with a prior negative biopsy. With recent advances in MRI technology, most prominently the advent of multiparametric MRI, MRI-targeted prostate biopsy (MRI-TB) has been gaining favor as a more accurate alternative to TRUS-Bx.
