“…Numerous studies of TMD patients confirmed the efficiency of MRI use with respect to clinical signs of the disorder (Moen et al, 2010). MRI was very useful in finding or controlling a therapeutic condylar position and its effects on the intraarticular function of TMJ, especially disc position.…”

“…Joint effusion, which is defined as a large collection of fluid in the joint space, has been detected as hyperintense signal on T2-weighted MR images and has been associated with inflammatory response [12], [24], [25]. Numerous researchers reported a positive relationship between joint effusion and TMJ pain [3], [26], [27], [28], [29], [30].…”

SummaryThe causes of pain symptoms in the temporomandibular joint (TMJ) and masticatory muscle (MM) regions may not be determined by clinical examination alone. In this review, we document that pain symptoms of the TMJ and MM regions in patients with temporomandibular disorders (TMDs) are associated with computed tomography and magnetic resonance (MR) findings of internal derangement, joint effusion, osteoarthritis, and bone marrow edema. However, it is emphasized that these imaging findings must not be regarded as the unique and dominant factors in defining TMJ pain. High signal intensity and prominent enhancement of the posterior disk attachment on fat saturation T2-weighted imaging and dynamic MR imaging with contrast material are closely correlated with the severity of TMJ pain. Magnetic transfer contrast, MR spectroscopy, diffusion tensor imaging, and ultrasonography findings have helped identify intramuscular edema and contracture as one of the causes of MM pain and fatigue. Recently, changes in brain as detected by functional MR neuroimaging have been associated with changes in the TMJ and MM regions. The thalamus, the primary somatosensory cortex, the insula, and the anterior and mid-cinglate cortices are most frequently associated with TMD pain.

“…Magnetic resonance (MR) imaging is currently considered a useful modality for TMJ imaging in patients with TMDs, particularly for examining the position and configuration of the disk [2][3][4][5], inflammatory pathological changes in the posterior disk attachment [6][7][8][9], and presence of effusion in joint spaces [5,[10][11][12], and for assessing the bone marrow edematous involvement [13]. Furthermore, the usefulness of a frequency-selective fatsaturation T2-weighted imaging technique has been reported for precise detection of TMJ effusion [14], inflamed posterior disk attachment [8], and edema pattern in the mandibular condyle [15,16].…”

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.

Abstract: Defined MR criteria that allow for comparative assessment are presented. According to these criteria, a large proportion of the patients referred for MR examination showed morphologic changes indicating TMJ pathology.
