The diagnosis and management of temporomandibular disorders (TMD) require both clinical and
imaging examinations of the temporomandibular joint (TMJ). A variety of modalities can be used to
image the TMJ, including magnetic resonance imaging (MRI), computed tomography (CT), cone beam
CT, ultrasonography, conventional radiography. The present review outlines the indications of the most
frequently used imaging techniques in TMD diagnosis.
Because of the anatomic complexity of the TMJ, imaging can be difficult. Choosing the proper
imaging technique is essential. Conventional radiography, nowadays, is of limited interest. The use
of flat plane films for TMJ pathology is not sufficient, because this joint requires three dimensional
imaging views. Osseous changes are better visualized with CT and cone beam CT. Cone beam CT
provides high-resolution multiplanar reconstruction of the TMJ, with a low radiation dose, without
superimposition of the bony structures. MRI is a noninvasive technique, considered to be the gold
standard in imaging the soft tissue components of the TMJ. MRI is used to evaluate the articular disc in
terms of location and morphology. Moreover, the early signs of TMD and the presence of joint effusion
can be determined. High-resolution ultrasonography is a noninvasive, dynamic, inexpensive imaging
technique, which can be useful in diagnosing TMJ disc displacements. The diagnostic value of highresolution
ultrasonography is strictly dependent on the examiner’s skills and on the equipment used.
