Synopsis

In the clinical settings, conditions in supra-aortic vessels include anatomical variants, steno-occlusive diseases, aneurysms, vasculitis, and shunt diseases. Luminal and vessel-wall morphology, and hemodynamics should be evaluated according to the purpose of imaging exams. TOF MRA is the standard technique. However, in-flow-effect related pitfalls should be recognized. Ultrashort TE MRA is an alternative especially for post-interventional evaluation. Contrast-enhanced MRA allows for improved luminal and vessel-wall contrast as well as hemodynamics. Arterial spin labeling technique can be also used for the evaluation of hemodynamics. This session will introduce MR technique and image findings based on various conditions in supra-aortic vessels.
