Screening for TMJ arthritis. The percentages of centers screening for TMJ arthritis among their JIA cohorts by either physical exam (P.E.) or history (Hx) are shown on the left hand side of the bar graph. Of those centers that used imaging as screening for TMJ arthritis, the percentages of the centers using the various imaging modalities [MRI, Xray (including orthopantomogram), ultrasound (UTZ), CT] are noted on the right hand side of the bar graph. More than one imaging modality per center may be employed.
