Twenty patients with vascular malformations of the head and neck who were examined by MRI were included in this study. Surgery was performed and histopathological diagnosis was obtained in all patients. On MRI examination, DCE-MRI was performed. Time of peak enhancement(T_peak) was determined from the time-signal intensity curves(TICs). MRI findings were then correlated with the histopathological type of vascular malformations. TThe high-flow lesion showed a rapid increase in TICs, whereas low-flow lesions showed a gradual increase. Our results indicate that DCE-MRI is useful in evaluating the flow characteristics of vascular malformations of the head and neck.
