Radiation dose reduction for musculoskeletal computed tomography of the pelvis with preserved image quality.

Objective: To analyze the impact of pelvic computed tomography (CT) technique optimization on estimated dose and subjective and objective image quality.

Materials And Methods: An institutional review board (IRB)-approved retrospective records review was performed with waived informed consent. Five CT scanners (various manufacturers/models) were standardized to match the lowest dose profile on campus via subjective assessment of clinical images by experienced musculoskeletal radiologists.
