【摘要】Objective To investigate the value of high-resolution magnetic resonance imaging (HR-MRI) of arterial walls in the diagnosis of cerebral artery dissection (CAD).Methods The patients diagnosed as CAD

and

completed

computed

tomography

angiography

(CTA),magnetic resonance angiography (MRA),digital subtraction angiography (DSA),and HR-MRI were enrolled retrospectively.The detection rate and diagnostic value of the 4 imaging techniques were compared and analyzed.Results A total of 15 patients were enrolled,5 had internal carotid artery dissection,7 had vertebral artery dissection,2 had middle cerebral artery dissection,and 1 had basilar artery dissection.HR-MRI revealed 11 intramural hematoma,9 intimal flap,3 double lumen sign,and 2 pseudoaneurysm.A total of 18 CADs were detected in 15 patients,17 (94.44％),14 (77.78％),5 (27.78％) and 6 (33.33
