Description
Mingyu Kim and colleagues test whether perfusion numbers from a contrast MRI scan hold steady across the software sold by different vendors. Such scans can act as a stand-in measure of tumor blood vessel growth in prostate cancer. The team drew on records of men who had prostate surgery between December 2021 and September 2022 for confirmed cancer.
Readings from these scans can shift with blood flow, the choice of input artery curve, the math model used, and the vendor's own processing steps. That spread matters when a number guides care or when clinics compare results. The study lays out where vendor systems agree and where they drift apart on the same patients. Its findings support care with cross-vendor checks before perfusion values are pooled or compared.
