arthrography
Pronunciation: ar-THROG-rah-fee
Imaging procedure using contrast material to visualize joint structures and guide injections.
Full Definition
Arthrography is a specialized imaging technique that involves the injection of contrast material into a joint space to enhance visualization of internal joint structures. In pediatric rheumatology, arthrography is primarily used to guide therapeutic intra-articular corticosteroid injections, particularly in joints that are difficult to access clinically such as the hip or sacroiliac joints. The procedure can be performed under fluoroscopic, ultrasound, or CT guidance, with ultrasound being increasingly preferred in children due to the absence of ionizing radiation. Arthrography helps ensure accurate needle placement and can provide additional diagnostic information about joint anatomy and potential complications.
Usage
Usage note: Specify imaging modality used (ultrasound, fluoroscopy, CT) in documentation.
