Synopsis

Keywords: Cartilage, Quantitative ImagingThe aim of this study was to evaluate degenerative changes in articular cartilage of patients with posterior root tear of the medial meniscus. Multi-echo quantitative T2 mapping was acquired on a 7T clinical scanner. For reference, age- and gender-matched healthy controls were scanned using the same 7T protocol. Arthroscopic evaluation of articular cartilage and menisci was performed in patients during the repair of posterior medial root tears. Significantly higher T2 values were found in the lateral and medial femoral cartilage of the patients compared to healthy controls.
