The phase-contrast MRI offers the advantage to combine precisely vascular flow measurements data with morphological images.
Even if the anatomy of the external carotid artery is well known, data obtained through Phase contrast MRI could permit to progress in several fields of cranio-maxillofacial surgery as for example arteriovenous malformations,radionecrosis, head and neck micro-reconstructive surgery.
The aim of this study is to establish and develop Phase-contrast MRI sequences for vascular flow characterization branches of the external carotid artery in healthy patients and in pathological cases.
