Keywords: Blood vessels, Blood vesselsBasi-parallel anatomic scanning magnetic resonance imaging (BPAS-MRI) is an MRI technique that can reveal the outer contour of the vertebrobasilar artery, even in the presence of occlusion. A total of 53 patients with 106 segments of blood vessels were scanned by BPAS+MRA, and the results were verified by comparing with VW-MRI. It was found that BPAS+MRA could significantly improve the detection rate of vertebrobasilar lesions, which was of great value for the diagnosis and differential diagnosis of arterial dysplasia, arteriosclerosis and arterial occlusion, and could improve the diagnostic confidence of radiologists.
