Hechler BL, et al. – A comparative review was performed on ultrasound (US) and magnetic resonance imaging (MRI), with regard to the temporomandibular joint in juvenile idiopathic arthritis. Findings revealed that dynamic imaging with high–resolution US improves sensitivity and specificity compared to static, low–resolution US. The outcomes suggested that US imaging following a baseline MRI can increase US sensitivity and specificity and might have a future role in disease surveillance.
