Acute MRI in Transient Ischemic Attack

NCT01531946 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 199

Summary

The purpose of this study is to detect acute ischemic lesions in patients admitted with symptoms of transient ischemic attack (TIA).

Diffusion weighted Imaging (DWI) is today one of the best ways to detect ischemic lesions after TIA. The problem is that this only gives the diagnosis in 30% of the cases.

It is possible that the addition of Arterial spin labeling (ASL) perfusion imaging and diffusion tensor imaging will make it possible to give a more accurate diagnosis.

Conditions

  • Ischemic Attack, Transient

Interventions

PROCEDURE

MRI Scan

Patients will have to spend additional 10min in the scanner. Additional scan modalities used: 1. Perfusion without contrast: Arterial spin labeling (ASL) with the ability of showing signs of ischemia. 2. Diffusion tensor imaging (DTI): Has a higher sensitivity than DWI in displaying local ischemic lesions. An overall 20min scan period.
