The ACVR is the American Veterinary Medical Association (AVMA) recognized veterinary specialty organization for certification of Radiology, Radiation Oncology and Equine Diagnostic Imaging. Go under the hindlimbs, just above the stifles, with tape, then bring the tape up and crisscross it above the stifles to rotate the hindlimbs medially so that the femurs are parallel to each other. To get the forelimb in a straight craniocaudal position, the patients head and body may need to be rotated left to right (FIGURE 27). Radiographic studies to assess the cranial cruciate ligament and aid in planning for tibial plateau leveling osteotomy (TPLO) are common in orthopedics. ORAU. There is no specific angle for the tarsus. Therefore, start by placing 1 to 2 inches of padding under the patients pelvis to aid in rolling the stifle down toward the table to be parallel with the table (FIGURE 2). These concepts will be described in more detail in part 2. The forelimbs should be extended caudally and secured with tape. The patient is positioned in dorsal recumbency. PPE should be inspected routinely for damage. The positioning is identical to that for the mediolateral view, with one addition: a radiolucent material such as cotton or a foam wedge is placed under the elbow to elevate it and rotate the shoulder into a supinated position (FIGURE 25). The Handbook of Radiographic Positioning for Veterinary Technicians is designed as a practical guide to positioning for radiographic studies in the small animal clinic. A one-year rotating internship or equivalent practice experience is generally required. Two markers are placed in this view, one indicating the recumbency of the patient and the other the beam direction. If needed, tape can be applied across the rostral portion of the mandible or behind the canine teeth on the maxilla to position the nose parallel to the table. She graduated from Purdue with an associates degree in veterinary technology in 2007. Place another piece of tape around the metacarpus, just above the first piece, pull it medially, and secure it to the table. What We Do Resources All veterinary professionals should practice simple methods of keeping exposure as low as reasonably achievable (ALARA), such as increasing distance from the tube head, using short exposure times, and using their knowledge and understanding of positioning to decrease the number of retakes. Tape around the proximal phalanges and extend the forelimb cranially.
