Synopsis

Keywords: Stroke, Neuro

Motivation: To apply the Precise IQ Engine (PIQE), a new high-resolution MR reconstruction technique, for Flow Sensitive Black Blood (FSBB) imaging.

Goal(s): To evaluate the usefulness of PIQE comparing the super-resolution FSBB images reconstructed from low-resolution FSBB images with short acquisition time using PIQE, low-resolution FSBB images, and high-resolution FSBB images.

Approach: On three FSBB images, cerebral microbleed (CMB) was identified and image quality was assessed for 121 patients who underwent FSBB images for CMB detection.

Results: PIQE made CMBs, blurred due to low resolution, clearly visible. PIQE-FSBB has image quality comparable to high-resolution FSBB even with shorter scan time.

Impact: PIQE, a technique that reconstructs high-resolution images from low-resolution images, was applied for FSBB imaging. The super-resolution FSBB reconstructed from low-resolution FSBB with short acquisition time had good quality, and was comparable to high-resolution FSBB for cerebral microbleeds detection.
