MRI is considered to be the reference method for the imaging and understanding of temporomandibular disease (TMD) , but it provides little or no detectable signal from cortical bone. A disc-shaped wireless detector (WD), which is more suitable for body superficial tissue or organ examination, is used to overcome the sensitivity limitation of conventional MRI in condyle imaging. This study aims to observe the capability of WD in showing the bone changes of TMD condyle on PDWI. Compared with the traditional MRI, WD is suitable for imaging the condyle bone changes of TMD patients, and significantly improves the image quality.
