Postoperative Mamma-MRT

Die kontrastmittelgestützte Mamma-MRT ist allen anderen bildgebenden Verfahren bezüglich der Sensitivität für den Nachweis von Brustkrebs deutlich überlegen und damit wichtig für das Follow-up nach brusterhaltender Therapie oder Mastektomie. Sie kann gut zwischen postoperativer Narbe und Tumorrezidiv unterscheiden, nicht aber zwischen granulomatös-entzündlichen Veränderungen und einem Rezidiv.

Postoperative Breast-MRI

Abstract

Contrast-enhanced breast MRI is superior to all other imaging modalities in terms of sensitivity for detecting breast cancer. This applies not only to invasive tumors, but also to intraductal carcinomas. MRI is therefore an important method for follow-up after

breast-conserving therapy (BCT) or mastectomy (ME) for breast cancer. As a contrast-enhanced technique, it has an excellent negative predictive value (NPV) in differentiating between postoperative scar and tumor recurrence. Limitations are evident with regard to the interpretation of increased vascularization within or at the periphery of postoperative scars. In these cases, granulomatous inflammatory changes cannot be reliably distinguished from a recurrence, so that percutaneous biopsy is usually indicated.
