This article discusses imaging techniques for visualization of the temporomandibular joint. Conventional plain film modalities are discussed briefly, with an emphasis on the more contemporary modalities, such as CT with cone-beam technology, MRI, and nuclear imaging, including single-photon emission computed tomography, and positron emission tomography. Indications, advantages, and limitations are discussed. As advancements in this area continue, our understanding of this complex joint and its pathology will follow, which will lead to more defined imaging indications and ultimately, to improved treatment outcomes.

The evolution and application of dental maxillofacial imaging modalities.
During the last decades, an exciting new array of imaging modalities, such as digital imaging, CT, MRI, positron emission tomography, and cone-beam CT (CBCT), has provided astounding new images that continually contribute to the accuracy of diagnostic tasks of the maxillofacial region. The most recent, cone-beam imaging, is gaining rapid acceptance in dentistry because it provides cross-sectional imaging that is often a valuable supplement to intraoral and panoramic radiographs. ⋯ The increasing trend toward the use of CBCT in dental offices may be expected to result in improved diagnosis, but with increased patient dose and health care costs. Using CBCT as a secondary imaging tool helps optimize health-to-risk ratio.
