Noncontrast MRA found noninferior to CTA for DIEP flap planning

This cohort study of 131 women undergoing delayed unilateral DIEP flap breast reconstruction compared an optimized noncontrast MRA protocol (n=81) to standard contrast-enhanced CTA (n=50) for preoperative perforator mapping. The study reported that MRA significantly reduced operative time and pedicle dissection time compared with CTA, with no significant differences in baseline perforator characteristics between groups. The authors concluded that noncontrast MRA is a clinically reliable, noninferior alternative to CTA for DIEP flap planning.

Most relevant for: Patients undergoing delayed DIEP flap breast reconstruction requiring preoperative perforator imaging.
