Abstract
Objective To investigate the role of high-resolution magnetic resonance imaging (HR-MRI) in the diagnosis of vertebrobasilar dolichoectasia, and to compare HR-MRI vascular wall imaging sequence with computed tomography angiography (CTA). Methods The imaging and clinical data of 25 patients who were diagnosed with vertebrobasilar dolichoectasia and underwent CT/CTA as well as HR-MRI during hospitalization during Feb. 2014 to Sep. 2015 were analyzed retrospectively. The study aimed to compare CT/CTA and HR-MRI according to the established criteria and explore the further value of HR-MRI vessel wall imaging. Results Comparison of CTA and HR-MRI revealed very good consistency of the measured diameter at mid-pons [intraclass correlation coefficient (ICC)=0.913, P<0.001], maximum diameter (ICC=0.951, P<0.001)and length of the BA(ICC=0.929,P<0.001).The consistency intensity of CTA and HR-MRI was stronger concerning the lateral position [weighted kappa coefficient=0.773, 95% confidence interval (CI) 0.606-0.941, P<0.001]. The length of the intracranial segment of the vertebral artery can be accurately measured by HR-MRI, which was (32.02±6.29) mm on the left side and (36.66±6.76) mm on the right side. There were 5 patients combined with basilar artery plaque and 2 patients with vertebral artery dissection were detected by HR-MRI. Conclusion CT/CTA and HR-MRI demonstrate a very good consistency and reproducibility in the diagnosis of VBD. As a non-invasive examination, HR-MRI has high value in detecting the vascular wall characteristics of VBD, checking whether there are combined with other vasculopathy and identifying the causes of the disease.关键词
