| Research Abstract |
The purpose is to visualize the difference in protein concentration of joint effusion of the temporomandibular joint (TMJ) by FLAIR technique which is inversion recovery method of MRI and to clarify the relationship between the pain and the protein concentration. A diagnosis of pain by the signal intensity ratio (SIR) was indicated in TMJ with disc displacement without reduction. Furthermore, as a result of a study by setting the pain value and SIR, sensitivity: 0.75, specificity: 1.0, positive predictive value: 1.0, negative predictive value: 0.5, accuracy of 0.8 was obtained. It was suggested that by the SIR obtained from the JE, pain in the TMJ can be diagnosed.
