Associations between cerebral magnetic resonance imaging infarct volume and acute ischemic stroke etiology.

ABSTRACT:

Background

Identifying ischemic stroke etiology is necessary for proper treatment and secondary prevention. We sought to define associations between infarct volume and stroke subtypes.

Materials and methods

Inclusion criteria necessitated a Johns Hopkins Hospital inpatient admission (2017-2019) for ischemic stroke with confirmatory brain magnetic resonance imaging. Infarct volume was calculated using MRIcron© by a masked reviewer. Ischemic strokes were adjudicated using TOAST classification. Multivariable/multinomial logistic regression determined associations between infarct volume and stroke subtypes with interaction terms for infarct number and location. Stepwise adjustment accounted for potential confounders.

Results

Patients (N = 150) were on average 61 years old
