New Validated Method for Measuring Fat Graft Retention in the Breast with MRI

Abstract

In this study, we present a new method for measuring fat graft volume retention in the breast based on magnetic resonance imaging scans and a validation study to assess its accuracy and precision. The method was validated by 4 observers using the magnetic resonance imaging scans of 14 patients undergoing breast augmentation with fat grafting. The method was translated into software and was used to measure the change in breast volume from a preoperative scan to a postoperative scan recorded within 3 hours after the surgery, which was compared with the injected fat graft volume. The new method measured the injected fat graft volumes with an average systematic overestimation of 6.3% (SD, 10.5). The median interobserver variation was <7%. We propose that this new method can be a good alternative to previous techniques for clinical research purposes. The software can be made available upon request free of charge for use on the MeVisLab platform.
