Background and purpose Arterial calcifications on unenhanced CT scans vessel wall lesions MRI are often used interchangeably to portray intracranial arterial disease. However, the extent of pathology depicted with each technique is unclear. We investigated presence distribution these two imaging findings in patients a history cerebrovascular Materials methods analyzed data from 78 admitted for stroke or TIA at our institution. Vessel were assessed 7 T sequences, while scans. The number lesions, severity internal carotid artery (iICA) calcifications, overall visually arteries. Results At least one lesion calcification was 69 (88%) patients. Only iICA vertebral arteries (VA) showed substantial both lesions. other vessels almost exclusively associated ( p = 0.013). Conclusions increases calcifications. Nonetheless, shows remarkable differences. These support need combined approach examine
