Arterial Spin Labeling MRI Focal Abnormalities in Refractory Epilepsy

Mayo Clinic·interventional·Posted Jan 21, 2013·Updated Mar 6, 2015

In Brief

A clinical study evaluating Arterial Spin Labeled (ASL) MRI sequence for Focal Epilepsy. Completed, enrolled 73 participants across 1 site.

Detailed Summary

This study will evaluate a type of Magnetic Resonance Imaging (MRI) sequence called arterial spin labeling (ASL). The investigators hope that ASL can better localize areas of the brain (lesions) that cause epilepsy. This type of MRI does not require contrast, does not use any radiation, and adds on 4 minutes to the routine MRI that is done for patients with epilepsy. The study hypothesis is that in patients with refractory epilepsy, Arterial Spin Labeling (ASL) MRI will show areas of abnormality in the brain to the same degree as single-photon emission computerized tomography (SPECT) and positron emission tomography (PET) studies.

Interventions

Arterial Spin Labeled (ASL) MRI sequencedevice

The Arterial Spin Labeled (ASL) MRI sequence is an MRI technique in which arterial blood undergoes spatially selective inversion to label the arterial blood. This is a magnetic technique and does not require contrast. The tagged blood is imaged and areas of hypoperfusion or hyperperfusion are revealed on the MRI sequence.
