“…2 Two observers independently assessed the presence, number, volume and pattern of acute DWI ischemic lesions. Based on published classifications and templates, [3][4][5] we identified: (1) strokes in pial artery territories (Pattern 1, ie, complete or incomplete territorial stroke involving the cortex and subcortical structures; (2) strokes in perforating artery territories (Pattern 2, ie, stroke in the territory of deep perforating branches, sparing the cortex junctional area); and (3) junctional strokes (Pattern 3) when located at the boundaries of 2 arterial territories. Multiple DWI lesions were defined as multiple noncontiguous infarcts and multiple pattern as DWI lesions belonging to distinct pattern.…”

Background and Purpose-In stroke attributable to spontaneous dissection of the cervical artery, it is unclear whether the occurrence and pattern of stroke depend on the degree of stenosis. Methods-In 147 consecutive dissection of the cervical artery patients with (nϭ88) and without stroke (nϭ59), we compared the number, volume, and patterns of cerebral diffusion-weighted imaging stroke lesions among patients with Ͻ70% stenosis (Group 1), Ն70% stenosis (Group 2), and occlusion (Group 3 Pϭ0.03). There were no differences in the breakdown of diffusion-weighted imaging lesion patterns according to degree of stenosis. Conclusions-The occurrence and diffusion-weighted imaging lesion patterns in dissection of the cervical artery patients may not be influenced by the degree of stenosis of the dissected artery. Occlusive dissection of the cervical artery was associated with larger infarcts.

“…Modifying the classifications of previous DWI studies [8,9,15,19,20], we specified 6 patterns of ischemic lesions: (1) In part A of the study, number, size and distribution of all hyperintense DWI lesions were compared between the two groups, irrespective of their appearance on ADC maps. In part B, the same comparisons were made for the subgroup of hyperintense DWI lesions with low ADC (i. e. only acute lesions).…”

“…In practice, etiology is inferred from clinical presentation and the pattern of ischemic lesions seen with brain imaging. [1][2][3][4][5][6][7] Unfortunately, interpretation of lesion patterns is confounded by significant vascular territory variations between individuals. 8 -13 In this regard, methods to image arterial perfusion territories are likely to have considerable value.…”

Background and Purpose-Recent advances in arterial spin labeling MRI have permitted noninvasive evaluation of vascular territories. In the present study, we quantitatively assess mixing of internal carotid and basilar artery blood through cerebrovascular anastomoses using vessel-encoded arterial spin labeling and a new postprocessing method. Methods-Vessel-encoded arterial spin labeling was used to determine the territories of the internal carotid and basilar arteries in 14 healthy subjects and one patient with asymptomatic high-grade carotid artery stenosis before and after endarterectomy. Contributions to individual vascular territories were quantified using a voxelwise supply fraction algorithm and the results were correlated with MR angiography. Results-Vascular territories were consistent with cerebrovascular anatomy and the presence of pathology. The supply fraction method allowed quantification of mixed territorial supply arising from collateral flow and showed vascular supply changes in a patient with carotid artery stenosis after endarterectomy. Conclusions-Vascular

Lesion Patterns and Mechanism of Ischemia in Internal Carotid Artery Disease

Abstract: An acute ischemic lesion in ICA occlusive disease is mainly multiple. Border-zone infarction was mostly associated with territorial infarction. These results support the fact that embolism is the predominant stroke mechanism in ICA occlusive disease.
