Two novel applications of 3D amplified MRI (aMRI)
Motivation: We intend to employ advanced imaging methods to explain pathologic clinical scenarios involving the spine and optical nerve sheath. Motion in these applications is driven by cardiac pulsatility, and the pulsatile motion occurs across CSF-tissue boundary. Goal(s): In this work, we tested if cardiac-gated cine MR imaging combined with video amplification can visualize sub-voxel motion. Approach: Pulsatile motion profiles were extracted and quantitatively compared. Results: Pulsatile motion in healthy and pathological use cases are compared. Impact: Amplified MRI (aMRI) is a visualization method that shows pulsatile dynamics and is used to study brain pulsation. We have shown additional use-cases in spinal cord motion and optical nerve sheath dynamics.
