TL;DRAbstract
The development of new minimally ablative therapies for prostate cancer has led to an increase in the interest for imaging-guided biopsy comparatively to the traditional biopsy technique such as TRUS-guided 12-core systematic biopsy. The strategy of pre-biopsy Mp-MRI and targeted biopsy for prostate cancer management can be effective in detecting a greater proportion of cancers that are clinically significant and in better quality sampling (tumor volume and grade) compared to standard TRUS-guided biopsies. It may also be used as a triage test to rule out cancer and avoid biopsies. Targeting biopsies to an MRI-suspicious area can be carried out in several ways such as free-hand “cognitive” targeted biopsy under TRUS guidance, MRI-directed real-time biopsy (MRI guidance) or real-time virtual navigation system with fusion of the MR images to the ultrasound images, and targeted biopsy under TRUS/MRI fusion guidance.
