Temporal evolution of non-contrast CT markers of expansion relates to the dynamics of acute intracerebral hemorrhage.

ABSTRACT:

Purpose

The temporal evolution of non-contrast CT (NCCT) markers of intracerebral hemorrhage (ICH) expansion during the dynamics of acute ICH is understudied. We aimed to evaluate the temporal evolution of these markers and its relationship with ICH dynamics.

Methods

Single-center, prospective, observational cohort study on 271 ICH patients < 6 h. Patients underwent baseline NCCT and multiphase CTA, and 24-hour NCCT. NCCT markers included: irregular shape, satellite sign, and island sign (shape markers); heterogeneous density, hypodensities, swirl sign, black hole sign, blend sign, and fluid level (qualitative density markers); and mean, standard deviation, and coefficient of variation hematoma density (quantitative density markers). The spot sign in first phase of multiphas
