Screening for prostate cancer with first-line MRI less cost-effective than first-line PSA testing

A cost-effectiveness analysis found that first-line MRI-based screening for prostate cancer is less effective and more costly than first-line PSA testing. Despite free MRI costs, the first-line approach resulted in increased false positives and overdiagnosis without substantial reductions in mortality.
