Magnetic Resonance Imaging and Dynamic CT Scan in Cervical Artery Dissections Stroke 25:576-581, Zuber,M.,et al, 1994 See this aricle in Pubmed Article Abstract A typical magnetic resonance imaging picture of cervical artery dissect5ion was observed in 12 of 15(80%)patients and in 13 of 19(68%) dissected vessels.The sensitivity of magnetic resonance imaging was higher in internal carotid(78%)than in vertebral(60%)dissections and in stenotic- type dissections(85%)than in occlusive or aneurysmal-type dissections.The dynamic computed tomographic scan showed the mural hematoma in 11 of the 12(92%)patients and in 12 of 15(80%)dissected vessels.Routine 0.5-T magnetic resonance imaging with axial slices is a sensitive technique for the diagnosis of dissection,but in about 20%of patients with cervical artery dissection magnetic resonance imaging will demonstrate no typical abnormality.Dynamic computed tomographic scans are a sensitive neuroimaging procedure to confirm the presence of the mural hematoma,but it needs to be directed by prior angiography.
