Step 1: Understanding the Concept:
Contrast radiography utilizes radiopaque substances (such as iodinated contrast media) to outline soft tissue structures that are otherwise poorly visible on plain survey radiographs.
Step 2: Detailed Explanation:
Let us define the contrast diagnostic procedures mentioned:
- Reticulography: Contrast radiographic evaluation of the reticulum in ruminants (rarely used, but would apply to the stomach).
- Arthrography: Contrast radiography of a joint space, used to evaluate joint capsule integrity, cartilage defects, and intra-articular structures.
- Fasciagraphy (or Tenography): Contrast examination of tendons, fascia, and their associated synovial sheaths to identify adhesions, tears, or tenosynovitis.
- Cystography: Contrast evaluation of the urinary bladder (using positive, negative, or double-contrast methods).
Step 3: Final Answer:
Thus, contrast radiography of tendons and associated fascial/sheath structures is termed fasciagraphy.
