Patient motion frequently degrades clinical MR
examinations, but its prevalence remains unknown. We
sought to assess the prevalence of significant patient
motion in MR examinations of the neuroaxis by manually
evaluating images sent to PACS. 55 of the 175 total
neuroaxis MRI examinations completed in one calendar
week were sent to PACS with at least some motion
degradation (31.4%). We conservatively estimate that
motion-related imaging costs approach $296,092.00/year
at our institution. Since patient motion may be common
in the global MR community, we suggest that attention be
directed toward providing more practical solutions to
this common problem.
