Improving Prostate Cancer Detection Using MRI-Targeted TRUS-Guided Biopsy

The standard care TRUS-guided biopsy is a schematic 12 core biopsy scheme with 2 cores taken from each of standard 6 zones. In some cases, the radiologist may take additional cores beyond 12 if suspicious areas are suspected from clinical findings or TRUS. TRUS-guided biopsies will be performed by a designated group of radiologists. An overall score out of 5 of likelihood of clinically significant prostate cancer will be recorded for each individual patient. The biopsy will be scheduled within 1 week of referral.

"A designated radiologist will perform all MRI exams. The radiologist will identify locations of the prostate gland of the standard 12 cores to be taken and any additional lesions deemed to be suspicious for cancer.~The procedure for the MRI-targeted biopsy will be exactly the same as the TRUS-guided biopsy except that an additional 2 cores per area may be taken beyond the standard 12 cores in areas that were previously identified by MRI on the map. The systematic 12-core biopsy will always be performed first. The radiologist performing the MRI-targeted biopsy will review the MRI targets prior to the biopsy as per standard of care, and he/she will also perform the TRUS-guided biopsies for this group. Patients will be scheduled for their biopsy \~ 1 week after the MRI."
