Researchers have developed a new artificial intelligence (AI) system to help radiologists improve their ability to diagnose prostate cancer. The system called FocalNet helps identify and predict the aggressiveness of the disease by evaluating magnetic resonance imaging (MRI) scans and does so with nearly the same level of accuracy as experienced radiologists. FocalNet is an artificial neural network which uses an algorithm that comprises more than a million trainable variables according to researchers including Ruiming Cao from University of California Los Angeles. For the study published in the journal IEEE Transactions on Medical Imaging the team trained the system by
