The effect of cerebral blood perfusion on the correlation between cerebral stroke onset time and synthetic T2 mapping: a pilot study.

ABSTRACT:

Background

In patients with acute stroke with an unknown onset time, the T2 relaxation time (qT2) in the region of diffusion restriction is associated with the time from symptom onset. We hypothesized that cerebral blood flow (CBF) status assessed using arterial spin labeling magnetic resonance (MR) imaging would influence the association between qT2 and stroke onset time. The purpose of this study was to preliminarily investigate the effects of diffusion-weighted imaging-T2-weighted fluid-attenuated inversion recovery (DWI-T2-FLAIR) mismatch and T2 mapping value changes on the accuracy of stroke onset time in patients with different CBF perfusion statuses.

Methods

A total of 94 patients with acute ischemic stroke (symptom onset time ≤24 h) admitted to the Liaoning Thrombus
