Keywords: Stroke, StrokeThis study mainly investigated if high-resolution vessel wall MRI (HR-VWI) can predict postoperative restenosis before drug-coated balloon (DCB) treatment. We included 76 patients who underwent HR-VWI examination before DCB treatment. DSA measurement was assessed 6 months after operation to determine vessel restenosis, classifying patients into three groups of no stenosis, mild stenosis (<50%), and restenosis (>50%). Significant differences among three groups were observed in plaque length, lumen area of MLN, degree of stenosis, enhancement amplitude and plaque burden. Plaque length and EA were independent prognostic factors of postoperative restenosis. Therefore, HR-VWI has potential to predict postoperative restenosis before DCB treatment.
