Which imaging modality is typically first used in musculoskeletal trauma?

X-ray is typically the first imaging modality used in musculoskeletal trauma due to its availability, speed, and effectiveness in identifying fractures and other bone-related injuries. X-rays provide a quick view of the skeletal structure and can often reveal significant abnormalities such as breaks, dislocations, and alignment issues, allowing for timely diagnosis and management.

Additionally, obtaining an X-ray is less expensive and requires less time than other imaging modalities, making it the preferred initial choice in acute trauma settings. While other imaging techniques like CT scans can offer more detailed views of complex fractures and soft tissue injuries, they are generally used after an X-ray has identified a need for further evaluation. MRI and ultrasound also have their roles in assessing soft tissue, cartilage injuries, and other non-bony structures but are not typically utilized as the first-line imaging in cases of acute trauma.
