Advances in the clinical application of MRI in temporomandibular joint disorders
With the development of temporomandibular joint(TMJ)imaging methods,magnetic resonance imaging has gradually be-come the preferred examination method for TMJ disorders,because it has no risk of ionizing radiation exposure and is a non-invasive ex-amination.It can clearly show the joint disc,joint effusion,condylar edema,masticatory muscle,biplate area and synovial lesions,which has great clinical application value.In this paper,the MRI manifestation and correlation of articular disc position and morpholog-ical changes,joint effusion,condylar edema and extrapterygoid muscles are discussed,in order to provide ideas for imaging diagnosis of temporomandibular joint disorders.
