Brief Summary
The dynamic angio-MR sequences with injection of contrast (CE ARM) allow the study of the vascular anatomy. These sequences, widely used in clinical routine have shown their utility, in particular in the detection of the cerebrovascular diseases. The 4D flow MR sequences allow to quantify arterial parameters such as the speed of the circulating flow. By allowing an anatomical analysis and a functional analysis of quantitative parameters, 4D flow MR sequences could replace 1/ the currently used dynamic MRA sequences that are less precise in term of spatial and temporal resolution; 2/ the invasive exploration by DSA for the detection of vascular lesion and complete the exploration of the cervico-encephalic vascular pathologies by providing hemodynamical measures not yet accessible in clinical settings. In this context, the aim of the study is to evaluate the feasibility and the clinical usefulness of this 4D Flow technique to image brain vascular disorders including steno occlusive disorders. The evaluation will include several steps: 1/ optimization of acquisition parameters for the cranio-cervical arteries; 2/ comparison of two strategies for the post-processing 3/ feasibility for imaging of brain vascular disorders.
