[Magnetic resonance angiography].

Magnetic resonance angiography (MRA) is a non invasive method for studying the morphology and the hemodynamic of vessels. MRA is becoming well-established for aorta examination and has replaced aortography. MRA is very competitive in screening for renovascular hypertension, intracranial aneurysm, for evaluation of the carotid bifurcation and diagnosis of venous sinus thrombosis. In the future, clinical applications will include pulmonary and coronary arteries.
