“…On the other hand, according to a longitudinal study of MR imaging by Chiba et al [79], a reduction in joint pain does not correlate with disappearance of bone marrow edema pattern in most joints. Therefore, they concluded that bone edema pattern does not always contribute to the occurrence of joint pain in patients with TMDs [79].…”

“…TMJ remodeling is difficult to distinguish from a post mechanical injury inflammatory process. OA is frequently related to bone marrow abnormalities, and a symptomatic TMJ is accompanied by bone marrow changes with an osteoarthritic mandibular condyle, showing an increasing signal intensity on proton density-weighted MR images [79], [98].…”

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.

“…In another study, we suggested that pain was more severe in TMJs with marrow edema of the mandibular condyle than in those with osteonecrosis [58]. However, another study has suggested that bone marrow edema pattern in the mandibular condyle does not always contribute to the occurrence of joint pain in patients with TMJ disorders [59].…”

“…Fat content in the TMD group was statistically significantly lower in the joints with pain and bony changes than those without pain or bony changes. TMJ pain can have a variety of sources, including inflammatory changes in the posterior disc attachment [32], the presence of inflammatory mediators in the synovial fluid [33], excessive joint effusion [34,35], and bone marrow edema [9,[35][36][37][38][39][40][41]. It has been reported that the risk and degree of pain in TMJs with an abnormal bone marrow signal were significantly higher than those in TMJs with a normal bone marrow signal on MRI [37,42].…”

Assessment of bone marrow fat fractions in the mandibular condyle head using the iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL-IQ) method

et al. 2021

The prevalence of temporomandibular joint disorder (TMD) is gradually increasing, and magnetic resonance imaging (MRI) is becoming increasingly common as a modality used to diagnose TMD. Edema and osteonecrosis in the bone marrow of the mandibular condyle have been considered to be precursors of osteoarthritis, but these changes are not evaluated accurately and quantitatively on routine MRI. The iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL-IQ) method, as a cutting-edge MRI technique, can separate fat and water using three asymmetric echo times and the three-point Dixon method. The purpose of this study was to analyze the quantitative fat fraction (FF) in the mandibular condyle head using the IDEAL-IQ method. Seventy-nine people who underwent MRI using IDEAL-IQ were investigated and divided into 1) the control group, without TMD symptoms, and 2) the TMD group, with unilateral temporomandibular joint (TMJ) pain. In both groups, the FF of the condyle head in the TMJ was analyzed by two oral and maxillofacial radiologists. In the TMD group, 29 people underwent cone-beam computed tomography (CBCT) and the presence or absence of bony changes in the condylar head was evaluated. The FF measurements of the condyle head using IDEAL-IQ showed excellent inter-observer and intra-observer agreement. The average FF of the TMD group was significantly lower than that of the control group (p < 0.05). In the TMD group, the average FF values of joints with pain and joints with bony changes were significantly lower than those of joints without pain or bony changes, respectively (p < 0.05). The FF using IDEAL-IQ in the TMJ can be helpful for the quantitative diagnosis of TMD.
