This meta-analysis evaluated randomized clinical trial results to provide more definitive guidance on the role of EVT for patients with stroke with large infarcts based on perfusion metrics. The results showed that the effectiveness of thrombectomy is uncertain regarding the safety and efficacy of thrombectomy for patients with limited areas of at-risk tissue. EVT may be beneficial for those with intermediate perfusion mismatch (ratio of 1.2-1.8 or volume of 10-15 mL) but not for those with low perfusion mismatch (ratio <1.2 or volume <10 mL).

Compared to traditional energy-integrating CT detectors, photon-counting CT allows greater spatial and contrast resolution of small channels containing nerves, arteries, and normal anatomy such as the cochlear cleft and cochlear and vestibular aqueducts. This review article updates the existing literature by redefining these structures in greater resolution.
