What is the correlation between Juvenile Idiopathic Arthritis and the image appearance of MRI, CT, and CBCT findings in TMJ? A systematic review

Abstract Objective: To investigate the relation of the appearance of signs in the MRI, cone-beam computed tomography (CBCT), and conventional computed tomography (CT) images of TMJ from patients with JIA using conducting a systematic review.Materials and methods: Electronic searches in PubMed, Embase, Web of Science, Scopus, Lilacs, and The Cochrane Library were conducted to identify studies investigating JIA and imaging findings. Inclusion criteria were: original articles studies based on humans and systematic reviews, studies enrolling patients with less than 18 years with diagnostic of JIA, use of ILAR criteria and one type of image exam (MRI, CBCT, or CT), and papers in the English language.Results: Six studies fulfill the eligibility criteria: four used MRI and two CBCT and all analyzed imaging findings in pathological TMJ with JIA. The results showed that enhancement of the synovial membrane, condylar erosions, and flattening are the most prevalent imaging findings of JIA.Conclusion: MRI exams are more specific in anomaly detection in TMJ in comparison to CBCT and CT. Also, the results must be correlated to clinical signs to provide a correct diagnosis.Clinical Relevance: This study indicates the most prevalent imaginological signs of JIA to provide early and correct diagnosis for the disease.
