Sagittal localizer magnetic resonance (MR) angiogram illustrates the positioning of a two-dimensional phase-contrast MR section to measure the volume flow through the internal carotid arteries and basilar artery in a patient with symptomatic stenosis of the right internal carotid artery.

3. Fig 2
Selective angiograms of the right common carotid artery of a 52-year old woman before (a) and after (b) carotid angioplasty with stent placement (CAS) of the 90% stenosis in the right internal carotid artery (ICA). Quantitative magnetic resonance flow values before (c) and after (d) CAS are obtained by integrating across manually drawn regions that enclose the vessels. 1, Right ICA; 2, left ICA; 3, basilar artery.

4. Fig 3
Quantitative changes in volume flow in the ipsilateral internal carotid arteries (ICAs) in patients with symptomatic ICA stenosis before and after carotid angioplasty with stent placement (CAS) (top) or carotid endarterectomy (CEA) (bottom). After CAS or CEA, the mean volume flow in the ipsilateral ICA significantly increased (P < .001).

5. Fig 4
Quantitative changes in volume flow in the ipsilateral internal carotid artery (ICA) in patients with symptomatic ICA stenosis after carotid angioplasty with stent placement (CAS) or carotid endarterectomy (CEA), as a function of the degree of the preintervention stenosis (%) in the ipsilateral ICA. Both CAS (r = 0.30) and CEA (r = 0.33) demonstrate a positive correlation between the degree of stenosis and volume flow increase in the treated ICA.

6. Fig 5
Quantitative volume flow (mean ± SEM) through the cerebripetal arteries in patients with symptomatic internal carotid artery (ICA) stenosis before and after carotid angioplasty with stent placement (CAS) or carotid endarterectomy (CEA), as well as in control subjects. Significant differences in volume flow between patients and controls; *P < .01; **P < .05.
