Al-Smadi AS, et al. - Via a study on 31 retrospectively identified patients with 38 intracranial large-vessel arterial occlusions, the researchers intended to investigate the diagnostic accuracy and reliability of black-blood MRI for the intraluminal detection of the occlusion. Relatively stronger grade 2 intraluminal T1 hyperintensity in chronic/incidental vs acute/subacute occlusions was noted. Hence, the contributors concluded high diagnostic accuracy and reliability of lack-blood MRI with or without contrast in evaluating intracranial large-vessel arterial occlusions with near-equivalency to DSA and CTA.
