Machine learning may aid evaluation of prostate MRI

By Erik L. Ridley, AuntMinnie staff writer July 20, 2016 — Multiparametric prostate MRI exams can be difficult to interpret, particularly for those who aren’t expert genitourinary radiologists. Machine-learning software may be able to make that task a lot easier, however, according to a proof-of-concept study from the University of California, Los Angeles (UCLA). A UCLA research team found that a machine-learning algorithm could perform “on par” with the level of accuracy reported in the literature for subspecialized genitourinary radiologists after training and testing the software on a small set of cases that included multiparametric MRI scans and corresponding whole-mount histopathology slides. “It could enable and assist general or novice radiologists or urologists to really increase their standard of care,” Dr. Nelly Tan said. She shared the group’s initial experience with…
