Value of superb micro-vascular imaging in predicting ischemic stroke in patients with carotid atherosclerotic plaques

Figure 1 Superb micro-vascular imaging vascular grading in patients with carotid atherosclerosis. A: Blood flow level 0 in plaque; B: Blood flow level I in plaque; C: Blood flow level II in plaque; D: Blood flow level III in plaque.

Figure 2 Carotid plaque Tic analyses. A: Stroke patient, time-to-peak = 12.8 s, enhancement intensity = 9.6 db; B: Non-stroke patients, time-to-peak = 13.4 s, enhancement intensity = 8.1 db.
