Peri-ictal magnetic resonance imaging characteristics in dogs with suspected idiopathic epilepsy.

ABSTRACT:

Background

The pathophysiology of changes in magnetic resonance imaging (MRI) detected after a seizure is not fully understood.

Objective

To characterize and describe seizure-induced changes detected by MRI.

Animals

Eighty-one client-owned dogs diagnosed with idiopathic epilepsy.

Methods

Data collected retrospectively from medical records and included anatomical areas affected, T1-, T2-weighted and T2-FLAIR (fluid-attenuated inversion recovery) appearance, whether changes were unilateral or bilateral, symmetry, contrast enhancement, mass effect, and, gray and white matter distribution. Diffusion- and perfusion weighted maps were evaluated, if available.

Results

Seizure-induced changes were T2-hyperintense with no suppression of signal on FLAIR. Lesions w
