They found that if the MRI was clear, there was a 97% chance of not having a significant cancer. If it was positive, there was an 88% chance of having a significant cancer. This advance in imaging helps avoids unnecessary biopsies in many patients. It also allows more targeted biopsies using MRI-guided technologies to accurately sample the lesion.
