Magnetic resonance angiography of the head and neck vessels.
Stroke, a major cause of death and disability in the developed world, is usually caused by atherosclerosis, most commonly an arterioocclusive lesion at the carotid bifurcation. Numerous multicentre trials have demonstrated that carotid endarterectomy can reduce the risk of stroke in these patients. However, because of the morbidity of catheter angiography coupled with the risks of surgery, the ...
متن کاملGadolinium-enhanced 3D magnetic resonance angiography of the thoracic vessels.
MAGNETIC RESONANCE IMAGING has long been recognized as a useful tool for the non-invasive evaluation of the thoracic vasculature. Unlike computed tomography and conventional angiography, MRI is not associated with the concerns related to ionizing radiation exposure or to contrast-related nephrotoxicity. MRI is also capable of oblique image acquisition and multiplanar reformation, which aids the...
متن کاملCorrelation between magnetic resonance angiography (MRA) and quantitative coronary angiography (QCA) in ectatic coronary vessels.
Coronary artery ectasia (CAE) is defined as a dilatation of an arterial segment to a diameter at least 1.5 times that of the adjacent normal artery. The correct follow-up of ectatic vessels is hampered by the need for repeat angiograms. In this work we compared quantitative coronary angiography (QCA) measurements of the diameter of the proximal most ectatic part of coronary vessels, with corres...
