<P><B>Abstract</B></P> <P><B>Purpose</B></P> <P>We aimed to investigate the magnetic resonance imaging (MRI) features and clinicopathologic factors with recurrence of triple-negative breast cancer (TNBC).</P> <P><B>Patients and methods</B></P> <P>We identified 281 patients with 288 surgically confirmed TNBC lesions who underwent pretreatment MRI between 2009 and 2015. The presence of intratumoral high signal on T2-weighted images, high-signal rim on diffusion-weighted images (DWI), and rim enhancement on the dynamic contrast-enhanced MRI and clinicopathological data were collected. Cox proportional analysis was performed.</P> <P><B>Results</B></P> <P>Of the 288 lesions, 36 (12.5%) recurred after a median follow-up of 18 months (range, 3.6–68.3 months). Rim enhancement (hazard ratio [HR] = 3.15; 95% confidence interval [CI] = 1.01, 9.88; <I>p</I> = .048), and lymphovascular invasion (HR = 2.73, 95% CI = 1.20, 6.23; <I>p</I> = .016) were independently associated with disease recurrence. While fibroglandular volume, background parenchymal enhancement, intratumoral T2 high signal, and high-signal rim on DWI, were not found to be risk factors for recurrence.</P> <P><B>Conclusion</B></P> <P>Pretreatment MRI features may help predict a high risk of recurrence in patients with TNBC.</P>
