Quantitative MRI Imaging in Orthopedic Clinical Trials
Orthopedic trials have long depended on patient questionnaires and on radiographic joint space width, a measurement of what cannot be seen.

Validated scoring systems for rheumatoid arthritis, consensus profiles for compositional cartilage imaging and metal artifact reduction techniques for implants have made MRI a practical endpoint across arthritis and device trials. This issue reviews those methods and what sponsors must standardize to use them well.
