“…Moreover, a fluid-attenuated inversion recovery (FLAIR) sequence and fatsaturation techniques are also utilized for certain TMD cases in the clinical context. For example, FLAIR is usually applied to identify the component of joint effusion of pure fluid or coexisting inflammatory tissues, 27,28 which both manifest as high signal intensity on upper and lower joint spaces on T 2 WI (Fig. 3).…”

Temporomandibular joint disorders (TMDs) are a prevalent disease covering pain and dysfunction of temporomandibular joints and masticatory muscles, which can be detrimental to quality of life. Magnetic resonance imaging (MRI) is a powerful and noninvasive tool for the imaging and understanding of TMD. With the recent technical development of dynamic and quantitative MRI techniques, including diffusion‐weighted imaging, T2 mapping, and ultrashort/zero echo time, it is now feasible in TMD imaging and has been preliminarily investigated with promising results. In this review we will discuss the recent advances of MRI techniques in TMD and its future directions, and hope to highlight the scientific potential and clinical value of novel MRI techniques in diagnosing and treating TMD.

“…Interestingly, these data are in line with observations of human patients, who sometimes display such variability in synovial fluid volume. [33][34][35] Because FLSs are active players that contribute to cartilage damage in RA, we considered their potential role in the erosive process observed in the TMJ of K/BxN mice. We obtained and cultured primary FLSs from TMJs by using a protocol adapted from one that is usually used in our laboratory to harvest FLSs from limb joints.…”

Temporomandibular joint damage in K/BxN arthritic mice

Rheumatoid arthritis (RA) is an autoimmune disease affecting 1% of the world population and is characterized by chronic inflammation of the joints sometimes accompanied by extra-articular manifestations. K/BxN mice, originally described in 1996 as a model of polyarthritis, exhibit knee joint alterations. The aim of this study was to describe temporomandibular joint (TMJ) inflammation and damage in these mice. We used relevant imaging modalities, such as micro-magnetic resonance imaging (μMRI) and micro-computed tomography (μCT), as well as histology and immunofluorescence techniques to detect TMJ alterations in this mouse model. Histology and immunofluorescence for Col-I, Col-II, and aggrecan showed cartilage damage in the TMJ of K/BxN animals, which was also evidenced by μCT but was less pronounced than that seen in the knee joints. μMRI observations suggested an increased volume of the upper articular cavity, an indicator of an inflammatory process. Fibroblast-like synoviocytes (FLSs) isolated from the TMJ of K/BxN mice secreted inflammatory cytokines (IL-6 and IL-1β) and expressed degradative mediators such as matrix metalloproteinases (MMPs). K/BxN mice represent an attractive model for describing and investigating spontaneous damage to the TMJ, a painful disorder in humans with an etiology that is still poorly understood.

Background This systematic study aimed to compare and evaluate the diagnostic accuracy of different MRI sequences for detecting internal TMJ dysfunction. Materials and methods In this search strategy, we employed Google Scholar, PubMed, PubMed Central, Science Direct, and the Cochrane Library. Articles from the last decade were included in the search. The potential for bias in the included studies was evaluated. The search yielded 48 papers. However, only 10 papers met the criteria for inclusion in the systematic review. Results Various sequences such as FIESTA, FLAIR, T2 mapping, MERGE, HASTE, and dGEMRIC, have been discussed in this systematic review. Conclusion Among the various MR sequences, T2 mapping and dGEMRIC sequences help in the quantitative evaluation and assessment of early changes in disc derangement. These sequences provide in-depth diagnostic information complementary to conventional MRI for diagnosing early changes in the TMJ disc
