“…The present results for MR imaging confirmed that no significant differences in condylar bone marrow edema were observed between the painful and pain-free TMJ groups. Our results were consistent with those of Farina et al [22]. However, other reports have demonstrated a correlation between these findings [49,56].…”

“…Based on our multivariate logistic regression analysis, the odds ratio that a painful TMJ demonstrated the presence of enhancement was very high (29.30) and superior to those for changes in the anteroposterior disk position (3.00), sideways position of the disk (3.03), joint effusion (6.04), and bone marrow edema (3.51). Unlike conventional MR imaging, dynamic contrast-enhanced imaging can provide differential contrast enhancement between the soft tissues of the TMJ [21][22][23]25]. The authors would like to emphasize that the use of this technique affords a more accurate diagnosis for small alterations caused by TMJ synovitis.…”

“…In the present study, joint effusion was fairly common (60.5 %) in the painful TMJ group. It is difficult to correctly assess joint effusion as a predictor of TMJ inflammation and pain when focal or spot-like areas of SI are detected on plain T1/T2-weighted images [22]. As a consequence, the interpretation of joint effusion can often be too subjective.…”

“…The rate of contrast enhancement of the synovial tissues is mainly determined by the tissue vascularity and capillary permeability, both of which reflect the degree of inflammatory activity [24]. Although several studies have used dynamic contrast-enhanced MR imaging to investigate the root causes of TMJ pain, its clinical significance is not yet completely understood [22,23,25].…”

“…Dynamic MR imaging techniques such as echo-planar imaging [17], half-Fourier acquired single-shot turbo spinecho [18], fast imaging steady-state precession [19,20], spoiled gradient-echo [21], single fat-saturation T1-weighted 3D gradient-echo [22], and 2D fast low-angle shot [23] sequences are very powerful for detecting disk motion and any signal changes in the TMJ soft tissues. Contrast-enhanced MR imaging examinations provide additional information for evaluating the soft-tissue changes in the posterior and collateral disk attachments and capsule compared with conventional MR imaging [21].…”

Objectives To evaluate the correlations between temporomandibular joint (TMJ) pain and both conventional and gadolinium-enhanced magnetic resonance (MR) imaging characteristics in patients with temporomandibular disorders (TMDs). Methods T1-weighted, T2-weighted, and fat-suppressed contrast-enhanced T1-weighted MR imaging were performed in 80 TMD patients with the main complaint of TMJ pain. A kappa statistical analysis was performed to calculate the interobserver agreement between two of three radiologists. The relationships between TMJ pain and various MR findings were analyzed by multiple comparison test, Spearman's rank correlation test, Chi-square test, Student's t test, and multivariate logistic regression analysis. Results Significant correlations were observed between anterior disk displacement without reduction, joint effusion, and TMJ pain (p \ 0.01). The degree of contrast enhancement of the posterior disk attachment was correlated with the severity of TMJ pain, especially spontaneous pain (r = 0.725, p \ 0.01), while no correlation was observed in the masticatory muscle pain group. The correlation tended to be higher in the latero-central portions than in the medial portion of the mandibular condyle, although no significant difference was seen. Conclusions It has been suggested that fat-suppressed contrast-enhanced MR imaging techniques facilitate better understanding of the sources of TMJ pain, but not masticatory muscle pain, and could reflect TMJ synovial inflammation. The severity of TMJ pain was closely correlated with the degree of contrast enhancement. The above-mentioned correlation had a tendency to be higher in the latero-central portions of the mandibular condyle.
