3D CE-MRA can determine the type of dissection; display the true and false lumina, intimal flap, location and size of the initial entry and its relationship with the neighboring arterial orifice, and presence and amount of thrombus in false lumen. These data are important for the planning of surgical and endovascular therapy. Furthermore, it does not require iodinated contrast material, is radiation free, and has low morbidity. It combines the advantages of arterial angiography with those of MR imaging and, unlike CT angiography, does not require the removal of bone structures for adequate visualization of the vasculature.
