When evaluating suspected pelvic fractures, a pelvic X-ray or CT scan is the most appropriate imaging study. A pelvic X-ray provides a quick assessment of the bony structures of the pelvis, allowing for the identification of fractures, misalignments, or other injuries that may compromise the stability of the pelvis. However, a CT scan is often preferred for its detailed, cross-sectional images that can reveal not only bony injuries but also associated soft tissue damage, internal bleeding, or organ injuries that may not be visible on a standard X-ray.

This comprehensive evaluation is crucial in managing pelvic fractures, especially since these injuries can be associated with significant morbidity, including hemorrhage and instability. The CT scan's capability to provide 3D reconstructions also aids in surgical planning if needed, making it an invaluable tool in the management of suspected pelvic injuries.

In comparison, other imaging modalities, such as a chest X-ray or head CT, are not relevant to pelvic injury assessment, while ultrasound can be beneficial in certain circumstances (such as assessing for free fluid), it does not provide the detail necessary to evaluate complex pelvic fractures comprehensively.
