Magnetic Resonance Angiography of Cervicocranial Dissection Stroke 24:126-131, Bui,L.N.,et al, 1993 See this aricle in Pubmed Article Abstract This modality reliably showed vascular abnormalities and focal,segmental, or aneurysmal dilatation when correlated with conventional angiograms in three patients.Turbulence and magnetic susceptibility at the acute turn of the carotid in the petrous canal led to a false-positive diagnosis on magnetic resonance angiography in one patient(in whom subtle fibromuscular hyperplasis was found with conventional angiography but missed with magnetic resonance angiography).When combined with appropriate clinical signs,magnetic resonance imaging and magnetic resonance angiography can reliably establish the diagnosis of carotid dissection.Pitfalls of magnetic resonance angiography are discussed.
