Figure 4: Images from a M1 model of ischemic stroke with an autologous clot.

(a) A lateral pre-occlusion angiogram demonstrated normal MCA, its divisions and the position of the micro-catheter. (b) A lateral post-occlusion angiogram illustrated the perfusion deficit in the M1 divisions. (c) Local hyper-intensity was obvious in T2 scans. (d) Local hyper-intensity on DWI scans indicated ischemic lesions. A: anterior; P: posterior; R: right; L: left.
