Substantial shortening of brain and lumbar spine mr scan time using iqmr™ machine learning-based iterative image reconstruction algorithm: multi-site study

November 27, 2018

This study  aims to evaluate the scan time shortening potential of iQMR, a novel 3D image enhancement algorithm, in brain and lumbar spine MRI. iQMR provides image enhancement and increased Signal – to Noise Ratio (SNR), thus permitting substantial scan time reduction, without changing the imaging contrast, resolution, scanner hardware, or software. This study reports findings of 56 patients (37 brain, 19 lumbar spine) from three sites. Image quality, diagnostic quality, brain grey-white (GW) matter differentiation and artifacts’ appearance of iQMR-processed images acquired by short MRI protocols were compared to images acquired by standard MRI protocols.
