Gang M, Lee H, Kwak HS, et al. - In patients with occlusion or stenosis of the anterior intracranial artery, researchers conducted this study to assess contrast enhancement patterns on three-dimensional (3D) black blood (BB) contrast-enhanced magnetic resonance (MR) imaging. They retrospectively reviewed stroke 3D BB contrast-enhanced MR imaging and MR angiography findings of patients attending the emergency room for non-traumatic brain lesion assessment from January 2018 to January 2020. Out of 92 patients, 33 had complete occlusion in the anterior intracranial artery, 36 had high-grade stenosis, and 23 had low-grade stenosis. Bright contrast enhancement and high signal vessel sign on 3D BB contrast-enhanced MR imaging are associated with contrast stagnation of the occlusion site and slow flow of a distal portion of the occlusion site.
