We investigated the association between perfusion parameters in pretreatment MR imaging and survival outcome. This retrospective study included 61 consecutive patients (median age, 50 years; range, 27-77 years) diagnosed with TNBC who underwent pretreatment DCE breast MR imaging and definitive surgery. The median follow-up time was 46.1 months. Among pretreatment variables, a higher ve value and higher peak enhancement at pretreatment MR imaging were significantly associated with worse disease-specific survival in patients with TNBC. With further validation, these perfusion parameters have the potential to aid in the pretreatment risk stratification of patients with TNBC and in evidence-based clinical decision support.
