COMPARING ACCELERATION OF MRI BRAIN SCANS: COMPRESSED SENSING AND MACHINE LEARNING IMAGE PROCESSING TECHNOLOGIES

The report compared complete MRI brain scans exams that were acquired by the site’s routine scan (11 minutes 50 seconds) and by accelerated acquisition (5 minutes 50 seconds, 50% scan time reduction). Acquired images were processed and reviewed blindly by acknowledged neuroradiologists. The results demonstrate definite preference towards IIR-processed fast MRI brain  scans, for all …
