Cartilage Lesion Score: Comparison of a Quantitative Assessment Score with Established Semiquantitative MR Scoring Systems

摘要

Cartilage Lesion Score (or CaLS) is an MR-based technique with improved detection of longitudinal change in cartilage lesions compared with the established Whole-Organ Magnetic Resonance Imaging Score (or WORMS) and Boston-Leeds Osteoarthritis Knee Score (or BLOKS) and may be a preferred outcome measure with which to examine effectiveness of therapeutic interventions in clinical and epidemiologic studies of osteoarthritis.
