Combined Parallel Imaging & Compressed Sensing on 3D Multi-Spectral Imaging Near Metal Implants

Kevin M. Koch¹, Kevin F. King¹

3D Multi-Spectral Imaging (3D-MSI) can significantly reduce susceptibility artifacts near metal implants. In order to reduce these artifacts, 3D-MSI acquires a large amount of spectral and spatially encoded data. With such requirements, it is challenging to acquire high-resolution 3D-MSI images in a clinical environment. Here, we explore the combined effects of data-driven parallel imaging and compressed sensing in improving the resolution capabilities of 3D-MSI near a total knee replacement at 1.5T.
