Iodine (water) images reveal the highest grading score of visibility of in-stent lumen at marker location. DLP = dose length product; DAP = dose area product; CT = computed tomography; DSA = digital subtraction angiography; ICA = internal carotid artery; MCA = middle cerebral artery; BA = basilar artery; M1 = 1st segment of MCA; V4 = 4th segment of vertebral artery.
