Synopsis

Keywords: Motion Correction, Artifacts, Image Quality Assessment, Clinical Translation, Self-supervised Contrastive Learning

Motivation: MRI is essential for diagnostics, yet motion artifacts from patient movement can degrade image quality, risking misdiagnosis and necessitating rescans.

Goal(s): Our goal is to provide inline quality assessment of MRI scans to reduce rescans and improve diagnostic accuracy.

Approach: We implemented a deep-learning-based framework that evaluates image quality on a global and local level. The framework generates quality reports that can be displayed on the MR console.

Results: The framework reliably identified motion artifacts in abdominal and brain scans, providing practical quality feedback.

Impact: Our inline integration assessment for global and local image quality in MRI scans enables reliable detection of motion artifacts. This advancement allows for immediate corrective actions, improving diagnostic accuracy and optimizing imaging workflows.
