Imaging Assessments
The Dataset Description, Annotated Forms, Variable Guide, and Distributions for Longitudinal Radiograph and MR Image Assessments are available HERE.
A) Longitudinal Radiograph Assessments
Semi-quantitative scoring of radiographs, including Kellgren and Lawrence grades, OARSI joint space narrowing, osteophyte grades, and features of patello-femoral OA
- - Baseline to 84-month Longitudinal Knee Radiograph Assessments (PA, Lateral, and Full-limb (Hip-Knee-Ankle) Mechanical Alignment) (V01235XRAY)
Note: As of April 2016, the V012XRAY and V0123XRAY datasets are no longer available. The data have been updated and are now available in the Longitudinal Baseline to 84 Longitudinal Knee Radiograph Assessments dataset (V01235XRAY).
B) Longitudinal MR Image Assessments
Semi-quantitative Whole-Organ Magnetic Resonance Imaging (WORMS) scoring for presence and severity of structural features related to OA, including cartilage lesions, meniscal damage, bone marrow lesions, and osteophytes.
- - Baseline, 60-month, 84-month MRI Assessment (V035WORMS)
- - Baseline to 30-month Incident Radiographic OA (V02WORMS_INCIDENTROA)
- - Baseline to 30-month Subset of Knees with Baseline OA (V02WORMS_BLROA)
- - Baseline to 15-month Incident Knee Symptoms Cases and Controls (V01WORMS)
