[Aortic dissection: the role of diagnostic imaging, with special reference to magnetic resonance imaging and its implications in the pathogenesis].
The aim of this work was to evaluate the usefulness of angiography, CT scan and MR imaging in the diagnosis of aortic dissection, on the basis of the authors' experience and literature review. Angiographic study is still considered the first choice technique in the diagnosis of aortic dissection, although it is considered not completely safe. CT scan allows to note the early thickening of the vessel walls (due to intraparietal bleeding) and the presence of calcifications in the thrombosed portion of the lesion. MR study allows multiplanar study of the lesions without contrast medium, and best visualization of subendothelial bleeding in dissections without intimal lesion.
