Impact of Mechanical Vibration During DWI on Diffusion Parameter Estimation in Human Kidneys

DWI leads to patient table vibration that may affect image quality, as has been demonstrated previously in phantoms and brain. We therefore investigated the impact of mechanical vibration during abdominal DWI on diffusion parameter estimation. Diffusion scans were performed on three subjects that were once in direct contact with the MR-system, thus experiencing vibration, and once without contact to the MR-System. The results demonstrate that the impact of vibration on diffusion parameter estimation, including micro-perfusion estimation, and also on the image intensity is only small. This holds true for standard measurement parameters.
