Correct answer: B — Contrast-enhanced MRI of both temporomandibular joints

TMJ arthritis in JIA can be clinically silent while impairing mandibular growth. Contrast-enhanced MRI best detects active synovitis and structural change; radiography and CT are less sensitive for active inflammation, and ultrasound is technically limited at this site.
