Background
Personal mobility devices (PMD) gained popularity due to their convenience. However, accidents involving PMD have also been on the rise. We retrospectively reviewed the injuries sustained in personal mobility devices accidents of 67 patients by radiological studies from the period of 2015 to 2019 in a single center tertiary hospital.

Educational Goals / Teaching Points
- Common and likely ethology of injuries - Pictorial review of common injuries seen in the brain, thorax and limb - Pictorial review of less common but significant injuries - The use of MRI as an augment to CT studies - Radiology playing an educational role in prevention of PMD accidents

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
- Severe injuries noted in PMD accidents are predominately in the head, thorax and limbs. - Radiographs and CT imaging are the main modalities used when imaging of PMD victims is required. - MRI may add additional useful information, particularly in ruling in and ruling out musculoskeletal or spinal cord injuries not well appreciated on CT.

Conclusion
Radiological investigation is important in the evaluation of PMD accident victims. The range of injuries are wide ranging with mortality usually involving the older victims. More advanced imaging is needed to help confirm or disprove of injuries, especially in the spine.
