Utilidad de la resonancia magnética en el diagnóstico y seguimiento de la patología aórtica

Cardiovascular magnetic resonance (CMR) is one of the best imaging techniques for assessing aortic disease since high-resolution morphologic and functional study can be carried out using sequences produced by spin-echo CMR, cine CMR, or multiphase contrast-enhanced CMR angiography. Although CT is more readily available for use in acute aortic disease, CMR provides crucial information for the diagnosis of intramural hematoma and for determining prognosis in aortic dissection. Flow-velocity curves enable the hemodynamic repercussions of aortic dissection to be evaluated in both false and true lumina. Follow-up of aortic aneurysms and of outcome after endovascular therapy can be equally well performed using either CT or CMR. However, CMR is the technique of choice for the diagnosis and characterization of aortic coarctation.
