Accuracy and test–retest precision of quantitative cartilage morphology on a 1.0T peripheral magnetic resonance imaging system

OBJECTIVE: Quantitative magnetic resonance imaging (qMRI) of knee cartilage morphology is a powerful research tool but relies on expensive and often inaccessible 1.5 T whole-body equipment. Here we examine the reproducibility and accuracy of qMRI at 1.0 T by direct comparison with previously validated technology. METHODS: Coronal images of the knee were obtained in six healthy and six osteoarthritic participants. Two data sets were acquired …
