Intramammary edema of invasive breast cancers on MRI T-weighted fat suppression sequence: Correlation with molecular subtypes and clinical-pathologic prognostic factors.

Objective: To investigate the associations between different patterns of intramammary edema on preoperative 3.0 T magnetic resonance imaging (MRI) T-weighted fat suppression sequence and invasive breast cancer molecular subtypes and clinical-pathologic prognostic factors.

Methods: Between May 2014 and December 2020, 191 patients with invasive breast cancer who had undergone preoperative MRI and mastectomy or breast-conserving surgery were retrospectively enrolled.
