Prognostic prediction for lobar hemorrhage based on CT imaging markers

Abstract

Lobar hemorrhage is an important subtype of cerebral hemorrhage, which is associatedwith cerebral amyloidosis angiopathy (CAA) and has a high incidence rate, recurrence rate and disabilityrate. It is of great significance to predict its clinical prognosis using plain CT. Previous studies have foundthat the volume and morphology (irregular morphology of edges, island sign, spot sign, finger⁃like projection)of cerebral hemorrhage on CT images, combined with subarachnoid hemorrhage (SAH), CT cerebral smallvessel disease (CSVD) score, and CT radiomics, have certain predictive value for early hematoma expansion,neurological deterioration, and long ⁃ term poor functional prognosis, and recurrence in lobar hemorrhage.We review the predictive value of the above imaging features for the prognosis in lobar hemorrhage,providing a theoretical basis for precise prognostic stratification and individualized intervention.
