#arthrography

• Arthrography — A method of radiological or imaging examination of a joint, performed by previously injecting a contrast medium directly into the joint cavity. This procedure allows detailed visualization of radiolucent anatomical structures, such as cartilage, menisci, labrum, or internal ligaments, which cannot be precisely observed on a standard non-contrast X-ray.
• Arthrogram — The radiological image, film, or graphical record obtained following an arthrography, highlighting the internal anatomical details of a joint injected with a contrast medium. This visual medical record serves as an essential tool for identifying meniscal tears, hidden ligamentous ruptures, and deep cartilage defects that cannot be visualized via simple radiological techniques.
• Arthropneumography — A special method of joint radiological examination utilizing negative contrast, performed by the controlled injection of air, oxygen, or carbon dioxide directly into the joint cavity. This classic technical procedure opacifies and distends the synovial capsule, allowing the visualization of internal soft contours, ligaments, and cartilage on the radiographic film due to the density difference between the introduced gas and surrounding bone structures.
