ZTE-MRI have high feasibility of angle measurements such as femoral neck-shaft angle as well as bone erosions on temporomandibular joint in reflection of altered bone morphometry and function. In our study, X-ray taken as reference, good consistency of ulnar deviation angle and the length of ulnar styloid process was shown between each two modalities, but better consistency between ZTE-MRI processed with average intensity projection and X-ray. Significantly different number of bone erosions between ZTE-MRI and T1 weighted images were found. To sum up, ZTE-MRI might have potential in elevating diagnosis efficiency of detecting altered bone morphometry and function.
