[MRI navigated stereotactic prostate biopsy: fusion of MRI and real-time transrectal ultrasound images for perineal prostate biopsies].
A key challenge for prostate cancer (PC) therapy is to exactly diagnose tumor lesions. In this context we describe a new stereotactic prostate biopsy system, which integrates pre-interventional MRI with peri-interventional ultrasound for targeted perineal prostate biopsies. Furthermore, the novel system allows exact documentation of biopsies in three dimensions. ⋯ Perineal stereotactic prostate biopsies guided by the combination of MRI and ultrasound allow effective examination of suspicious MRI lesions. Each biopsy core taken is documented accurately for its location in 3-D enabling MRI validation and tailored treatment planning. The morbidity of the procedure was minimal.
