Patient motion during MRI isn’t random. It’s predictable.�
A 2026 US study by Yokoo et al. analyzing 68,517 exams found motion was significantly more likely in:
🔵 Inpatients (~3.3×) and emergency patients (~2.6×) �🔵 Patients ≥85 years (nearly 2×) �🔵 Severe obesity (+48%) �🔵 Male patients (+14%) �🔵 Black patients (+18%)�
Not biological differences — but reflections of how patients experience the scan.�
Three things that help, no new hardware needed:
�🔵 Tailored pre-scan instructions �🔵 Better positioning for at-risk patients �🔵 Shorter protocols for frail or elderly patients�
That instinct at the console? It’s pattern recognition. Now there’s data to back it up.�
