. Vessel wall imaging in patients with dissection plays an impotent role in the differential diagnosis of stenoocclusive processes of the main arteries of the head. However, the interpretation of changes in long-term periods remains difficulties. Purpose: to determine and compare the imaging patterns of the consequences of the postponed dissection using MRI and ultrasound. Materials and methods. 30 patients with confirmed dissection were examined for more than 1 year from the date of diagnosis. MRI was performed using vessel wall protocol imaging before and after contrast enhancement. Results. Postpone dissection imaging patterns were revealed: aneurysmal dilation of the artery (27%) and double lumen (20%) at the site of dissection; prolonged stenosis in 10% of cases, intimal flap — in 3% of cases. Occlusion persisted in 40% of cases. Conclusion. The use of MRI can improve the differential diagnosis of the causes of the stenоocclusive process of the main arteries of the head.
