Research advances in MRI on superficial zone and its injury of articular cartilage
Articular cartilage superficial zone (SFZ) is the top layer of articular cartilage and its injuries are common in clinic.Therefore its find in time and conducting the treatment can delay the progress rate of os-teoarthritis (OA) and alleviate the pain and economic burden of the patients.At present,MRI is the most sen-sitive noninvasive examination technique to evaluate articular cartilage injury.Conventional MRI is limited in the early detection of subtle degeneration before cartilage morphological changes existence,and articular carti-lage lesions can only be detected when the injury is in an irreversible stage.In recent years,with the develop-ment of high field intensity MRI techniques such as 3T and 7T,the detection of water molecules,collagen fi-bers and tissue anisotropy in cartilage has considerable advantages,which can make the quantitative analysis and functional imaging for the ultrastructure and biochemical composition changes of SFZ in articular carti-lage.This article reviews the latest research progress on diagnostic value of MRI on articular cartilage SFZ and injuries.
