Small cortical grey matter lesions show no persistent infarction in transient ischaemic attack? A prospective cohort study.

ABSTRACT:

Objectives

To find determining factors for persistent infarction signs in patients with transient ischaemic attack (TIA), herein initial diffusion lesion size, visibility on apparent diffusion coefficient (ADC) or fluid-attenuated inversion recovery (FLAIR) and location.

Design

Prospective cohort study of patients with clinical TIA receiving 3T-MRI within 72 hours of symptom onset and at 8-week follow-up.

Setting

Clinical workflow in a single tertiary stroke centre between February 2012 and June 2014.

Participants

199 candidate patients were recruited, 64 patients were excluded due to non-TIA discharge diagnosis or no 8-week MRI. 122 patients completed the study.

Primary outcome measures

The primary outcome was visible persistent infarction defined as 8-
