To introduce a simplified technique for MRI-guided core biopsies (MRGB) of the prostate in the supine position using large-bore magnet systems. Fifty men with a history of negative transrectal ultrasound-guided biopsies underwent MRGB in either a 1.5-T (13/50) or 3.0-T (37/50) wide-bore MRI unit. MRGBs were conducted with the patients in a supine position using a dedicated MR-compatible biopsy device. We developed a dedicated positioning device for the supine position. Using this device, the biopsies were performed successfully in all patients. Apart from minor rectal bleeding, only one patient developed a major side effect (urosepsis). Histology revealed prostate cancer in 25/50 (50Â %) patients. The new technique appears feasible. Its major advantage is the more comfortable and patient-friendly supine position during the biopsy without the need to modify the MRI systemâ[euro](TM)s patient table. â[euro]¢ A novel positioning device for MRI-guided prostate biopsies has been developed. â[euro]¢ Biopsies can be performed in the patient-friendly supine position. â[euro]¢ The positioning device can be utilised without modifying the MRIâ[euro](TM)s patient table.[PUBLICATION ABSTRACT]
