The Diagnostic Reliability of Various Magnetic Resonance Imaging sequences for the Early Diagnosis of Temporomandibular Disorders: A Systematic Review

Abstract

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
