Imaging modalities for temporomandibular joint (TMJ) is evolving continuously with the rapid emergence in various imaging techniques. Various imaging modalities depending upon the purpose and pathologic conditions are currently used to evaluate the TMJ. The correct diagnosis of TMJ dysfunction only by clinical examination cannot be made. Various imaging modalities which are routinely used are: routine radiographic examination, magnetic resonance imaging (MRI) and computer tomography (CT). Ultrasonography, arthroscopy and radionuclide examination are the secondary methods used for TMJ imaging. Arthroscopy is grouped as a mode of therapy. In the present paper, attempt is made to focus on the various imaging modalities for TMJ diagnosis and highlight their importance. In order to understand many TMJ pathologies in a better way, relevant normal anatomy of the TMJ has also been discussed.
