Ultrasound may be appropriate to screen for temporomandibular joint dysfunction in pediatric patients and adults who are claustrophobic or otherwise cannot undergo magnetic resonance imaging, some experts say.

Patients who have an abnormal ultrasound should then be evaluated with MRI, said researcher Dr. Lawrence Friedman.
