MRI-guided prostate biopsy to confirm and define the location(s) of cancer is a two-step process. Step one is getting an MRI. Based on the reading, step two is the biopsy guided by MRI findings combined with live ultrasound images. In comparison, micro-ultrasound-guided biopsy is a one-step process. The surgeon performs the biopsy based directly on live images from high-resolution ultrasound of the prostate gathered during the procedure through a probe inserted in the rectum. In the trial, half of the 678 men suspected to have prostate cancer underwent a micro-ultrasound-guided biopsy; the other half had a prostate MRI first, then the second step with a conventional biopsy guided by the MRI results. The researchers found no significant differences in diagnostic accuracy between the two approaches.
