Application of high-resolution magnetic resonance vessel wall image in the treatment of M1 segment stenosis of middle cerebral artery

•This study intends to investigate the clinical characteristics of patients with atherosclerotic stenosis of MCA and to summarize the indications for patients who undergo stenting.•HRMR-VWI MRI has a high value in diagnosing the location, morphology, and stability of plaques at the stenosis of the middle cerebral artery.•HRMR-VWI MRI can improve the safety and effectiveness of stenting in treating M1 segment stenosis of the middle cerebral artery and provide a sufficient basis for these patients to choose an appropriate treatment.
