Furthermore, intracranial remodeling may lead to an underestimation of plaque burden (based on the current definition of vessel stenosis >50%), and therefore an underdiagnosis of ICAD, particularly in the posterior circulation. As in the coronary vessels, remodeling occurs when plaque is present and may either augment or decrease the vessel lumen size. This study challenges the current theory that ICAD is purely based on degree of vessel stenosis. Finally, the authors found that the lumen begins to narrow (ie when remodeling fails to preserve the lumen) when plaque burden reached 55.3%. Furthermore, positive remodeling was associated with a trend towards culprit plaque classification. There was higher burden of plaque within the posterior circulation as compared to the anterior circulation and positive remodeling was more frequent in the posterior circulation (58% vs 31%). The authors identified 137 plaques, of which 56 exhibited positive remodeling, 53 negative remodeling, and 28 intermediate remodeling. Forty-five patients with ICAD with >50% stenosis in a large intracranial artery who also had a stroke or TIA in the distribution referable to that stenosis were included. In this study, the authors used High-resolution black blood MRI (BBMRI) to assess vessel remodeling in ICAD and its association with ischemic events.
