    The study included 351 patients with spontaneous intracerebral hemorrhage (sICH) treated between January 2020 and December 2023.

  • 2

    Of the patients, 91 (25.9%) exhibited early hematoma expansion (HE) within the study period.

  • 3

    A relative CT attenuation value of 33.35 Hounsfield units (HUs) was identified as the critical threshold for predicting HE.

  • 4

    Multivariate logistic regression analysis indicated that relative CT attenuation value could independently predict HE (p = 0.006).

  • 5

    The study found a sensitivity of 40.9% and specificity of 83.1% for predicting HE with a relative CT attenuation value of ≤33.35 HU.
