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

published on September 26, 2019

The report compared complete brain 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 MR scans, for all evaluation characteristics including scan time reduction, and image quality.

(A) Standard scan (Benchmark), AT=4:22 min.  (B) CS 4 Output (with Philips M-filter), AT=2:30.  (C) CS 8 Output, (with Philips M-filter), AT=1:15.  (D) iQMR Processed CS 8, AT=1:15min
