The aim of this study was to evaluate the perfusion of free flaps using DCE MRI. DCE covering the whole flap was performed in 11 patients. Signal increase over time in normally perfused flaps was similar to the reference tissue; there was no significant difference depending on the position within the flap. In flaps with compromised perfusion the increase was significantly lower than in the reference tissue. Normalized signal increase in adequately perfused flaps and flaps with compromised perfusion showed a significant difference. DCE MRI may be a valuable non-invasive tool to evaluate tissue perfusion of the complete free flap.
