A technique for transperineal high-dose-rate (HDR) prostate
brachytherapy and needle biopsy in a standard 1.5 T MRI scan-
ner is demonstrated. In each of eight procedures (in four pa-
tients with intermediate to high risk localized prostate cancer),
four MRI-guided transperineal prostate biopsies were obtained
followed by placement of 14­15 hollow transperineal catheters
for HDR brachytherapy. Mean needle-placement accuracy was
2.1 mm, 95% of needle-placement errors were less than
