In Dr. Andre’s study, motion artifacts were identified as the cause of repeated sequences in about 20% of MRI exams. Recent institutional data were used to compute a cost estimate, which was correlated with sequence time and severity of motion artifacts. “We calculated the financial consequence of repeat sequences due to motion artifacts to be about 115,000 US dollars of lost potential revenue per scanner per year.” 
Moreover, the repeated sequences can also create a cascade effect, resulting in increasing delays throughout the day and decreased patient throughput. “In addition, reducing or avoiding motion artifacts in MRI images can result in improved diagnostic confidence for the radiologists interpreting these studies, and aid them in formulating their diagnoses,” says Dr. Andre.
