    The study proposed a new imaging classification system (MCA-EB) for early branches of the middle cerebral artery using computed tomographic angiography.

  • 2

    A total of 271 early branches were identified in 215 middle cerebral arteries, with early temporal branches being more frequent than early frontal branches.

  • 3

    The mean diameter of early temporal branches was 0.86 mm, while early frontal branches had a mean diameter of 0.83 mm.

  • 4

    The MCA-EB classification includes four types, ranging from absence of early branches to combined early temporal and frontal branch variants.

  • 5

    Statistical analyses demonstrated no significant correlation between early branch diameter and distance from the MCA origin.
