Magnetic resonance imaging-directed transrectal ultrasonography-guided biopsies in patients at risk of prostate cancer
Magnetic Resonance Imaging
Although erMRI before TRUS-guided biopsies tended to give higher cancer yields the difference was not statistically significant. Reasons for this might include suboptimal localisation of the MRI findings and the biopsy location. Better methods for fusing MRI and TRUS images are presently being developed at our institution to allow more accurate targeting.
