Key clinical point: In women with high levels of background parenchymal enhancement (BPE), a simultaneous high-temporal/high-spatial resolution (HTHS) magnetic resonance imaging (MRI) protocol detected an additional 15.7 cases of breast cancer (BC) per 1000 patients than the standard high-spatial resolution MRI protocol while concomitantly decreasing the rate of unnecessary biopsies by ~10%.
Major finding: HTHS vs standard protocol improved the BC detection rate per 1000 patients (23.6 vs 7.9; P = .021), increased the positive predictive value of biopsy (16.0% vs 6.3%; P = .014), and decreased the rate of unnecessary biopsies by 9.8%.
Study details: This retrospective study included 1414 women with 1481 high-BPE examinations.
