Synopsis

Keywords: Stroke, Stroke

Motivation: Fast imaging is required for stroke protocols, and mid-field is generally assumed to require longer scan times.

Goal(s): Acquire a set of diffusion weighted, susceptibility weighted, and fluid attenuated inversion recovery images as rapidly as possible using a 0.5T head-only MRI equipped with high performance gradients.

Approach: We used a set of protocols designed to take advantage of the reduced geometrical distortions, short T1, and long T2 available at mid-field.

Results: A full set of diagnostic quality images was acquired in less than five minutes of scan time.

Impact: A 0.5T head-only MRI equipped with high performance gradients can potentially be used for rapid diagnosis of acute stroke. The small footprint, low field, and head-only design makes this magnet easier to site, improving MRI access for acute stroke patients.
