Motion during an MRI results in blurry, non-diagnostic images
“Motion artifacts represent a frequent cause of MR image degradation, […] resulting in substantial costs to the radiology department.”
Andre JB. et al. Towards quantifying the prevalence, severity, and cost associated with patient motion during clinical MR examinations. J Am Coll Radiol 2015; 12: 689-695.
This cost estimate accounts only the cost of repeat scans due to motion artifacts. It does not account for other potential additional costs, for example, sedation costs for patients, particularly children, who may be unable to lie still for an entire MRI exam.
