Advantages and disadvantages of conventional radiology in juvenile idiopathic arthritis
| Advantages | Disadvantages |
|---|---|
|
• Rapidity of performance • Applicability to all joints • Demonstration of joint space narrowing, disturbances of bone growth, and maturation • Detection of bone erosions • Validated scoring methods in children • Suitable for longitudinal evaluation of damage progression • Low cost • Widespread availability |
• Exposure to ionizing radiation • Inability to directly visualize cartilage and soft tissue inflammation • Late detection of bone erosions and joint space narrowing (normal in early stage) • Projectional superimposition • Limited use in some sites (TMJ involvement overlooked) • Misinterpretation of anatomic variation as bone erosion (wrist joint) |
TMJ temporomandibular joint
