Front & Hind Limb Radiology

  1. 1. EQUINE MEDICINE Large Animal Radiology: Digital X-Ray Front & Hind Limb
  2. 2. Equine Skeletal System
  3. 3. RADIOGRAPH PRINCIPALS Portable machine most commonly used FFD 20-30 cm (aka source-image distance (SID)) Cassette Marker-Cranial or lateral to limb Animal Positioning: Feet square Weight evenly distributed
  4. 4. Radiographic Aids Wooden Block: Allows cassette to extend below hoof Cassette Tunnel: Allows animal to stand on cassette Navicular Box: Supports foot for easier navicular films Cassette Holder: Tunnel with long handle Allows holder to be away from animal & primary beam
  5. 5. Radiographic Aids
  6. 6. Hoof Preparation Requires additional preparation Hoof should be cleaned of debris Trim sole & frog Remove shoe for some views Pack sulci of frog & sole to eliminate artifacts
