Juvenile Idiopathic Arthritis (JIA) is the most common musculoskeletal disorder in children. The temporomandibular joints (TMJs) are involved in majority of cases, and detection of early arthritic changes in these joints relies on contrast enhanced magnetic resonance imaging (MRI). However, with the paucity of evidence and consensus on the normal and pathologic changes in this small but complex joint, interpretation of TMJ MRIs remains to be difficult. This exhibit presents the normal growth related and arthritis related variations in the disease progression in TMJ MRIs of JIA patients. Read More

Whole body (WB) MRI is a valuable method for surveying the overall burden of systemic diseases such as juvenile idiopathic arthritis (JIA), directing further diagnostic and treatment approaches. Consensus-driven development and validation of a standardized WB-MRI scoring system for JIA has important clinical utility in timely detection and monitoring of disease activity, and serves as an outcome measure in research. We describe our experience utilizing a formal consensus approach amongst imaging and/or clinical JIA experts towards developing a novel WB MRI scoring system to assess disease activity in JIA.

Clinical assessment of the Sacroiliac Joint (SIJ) is limited due to the location and anatomy of the joint.<b> </b>Magnetic Resonance Imaging is a sensitive, non- invasive tool in detecting early SIJ inflammatory changes and structural damage in Juvenile Idiopathic Arthritis (JIA). The quantification of interval change of pediatric SIJs using MRI based scoring methods will serve as an important objective outcome measure for the assessment of disease severity and treatment effectiveness in JIA.
