Correct Answer: arthrography
thrography.
arthrography is the radiographic visualization of joints. this diagnostic procedure involves the injection of a contrast medium directly into the joint space to enhance imaging details. the contrast media used are usually iodine-based, which makes the internal structures of the joint, such as cartilage, tendons, and ligaments, visible on x-ray images. this is particularly useful for identifying abnormalities associated with the joint capsule, articular cartilage, and other intra-articular structures like the synovium and joint ligaments. arthrography is commonly used to assess joint conditions such as tears, degeneration, or diseases like arthritis.
in contrast, angiography is the radiographic examination of blood vessels. it involves the injection of a radiopaque contrast agent through a catheter into the bloodstream. the purpose of angiography is to visualize the flow of blood through the arteries and veins to detect abnormalities such as blockages, clots, or malformations.
cholecystography, on the other hand, is a radiographic examination of the gallbladder. for this test, a contrast medium that is absorbed by the liver and excreted into the bile is administered. the concentration of this contrast in the gallbladder allows for detailed imaging of the gallbladder's structure and function, aiding in the diagnosis of conditions like gallstones or cholecystitis.
myelography involves the introduction of contrast media into the subarachnoid space surrounding the spinal cord and nerve roots. this procedure is used to diagnose abnormalities of the spinal canal, including the cord and nerve roots, such as herniated discs, tumors, or stenosis.
each of these procedures—arthrography, angiography, cholecystography, and myelography—utilizes radiographic techniques tailored for visualizing specific body systems to aid in accurate diagnosis and treatment planning. however, for the specific task of visualizing the internal structures of a joint, arthrography is the appropriate procedure.
