SOC: standard of care; AB-MRI: abbreviated breast MRI; BMRI: breast magnetic resonance imaging; TN: true negative, TP: true positive; FN: false negative; FP: false positive; PPV: positive predictive value; NPV: negative predictive value; MIP maximum intensity projection; DCE: dynamic contrast-enhanced.
