Press the edge of a wooden spoon or similar radiolucent device on the medial aspect of the carpus, near the middle carpal joint. Markers should always be placed to indicate patient position and/or 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. The patient is placed in sternal recumbency. The forelimbs should be extended caudally and secured with tape. Understand the musculoskeletal, nervous and internal organ systems easily with these wall hangings in lamination or paper. This view is used in patients being evaluated for osteochondritis dissecans (OCD). However, many other items, such as compression bands, rope, and wooden spoons and cutting boards, can also be used.6 Some items are more cost-effective than others and can work just as well as more expensive options. Angle the affected tibia so that the femorotibial (stifle) joint and the tibiotarsal (tarsus) joints are at 90 angles (FIGURE 9). traveling intestinal parasite control training Cat skeletal anatomy poster created using vintage images. The wall chart shows the skeletal structure of the cat. In any radiographic study, especially digital studies, magnification resulting from patient size and exposure technique can be an issue. Small Animal Radiographic Techniques and Positioning is a practical, clinically applicable manual designed to aid veterinary technicians and nurses in correcting common artifacts in both film and digital radiography and in positioning the small animal patient for clear and consistent radiographs. The terms caudocranial and craniocaudal are used to describe the way the beam enters and exits a forelimb or hindlimb. If needed, place some cotton padding under the tarsus to lift it and aid in superimposing the femoral condyles (FIGURE 3). The superficial muscles. This 2-part article has given an overview of radiation safety, types of restraint for orthopedic radiography, and positioning techniques to obtain diagnostic radiographs of the skull, shoulder, elbow, stifle, pelvis, and feet.

The patient should be positioned in lateral recumbency with the affected forelimb on the table closest to the plate or cassette. Again, in some cases, if the condyles are not superimposed, the cotton from the tarsus can be removed and applied under the stifle. We will continue this discussion in part 2. To separate the phalanges, take a 0.5-inch wide piece of tape, wrap it around P2, and pull the toe cranially. Place another piece of tape around the metacarpus, above the first piece, distal to the carpus. Center over the elbow and collimate to include half of the humerus and half of the radius and ulna (FIGURE 43). Abduct the nonaffected limb out of the view by taping it to the table. Barn managers, racing stables, 4-H club members, endurance riders, event riders, carriage drivers, grooms and horse owners can now put our charts to better use. Similar to the mediolateral shoulder view, tape around the unaffected carpus, pull the leg across the body caudodorsally, and secure the tape to the table (FIGURE 37). She hopes to combine her love for animals and writing in the future to pursue a career in journalism for the veterinary medicine profession. Collimate to include the wings of the ilium and a small portion of the proximal tibias, just caudal to the femorotibial joints (FIGURE 23). NAVTA J Oct/Nov 2015:16-17. navta.net/?page=ZoetisSurvey. X-rays differ from some other forms of electromagnetic radiation because their very short wavelength allows them to penetrate matter, including cells. The terms caudocranial and craniocaudal are used to describe the way the beam enters and exits a forelimb or hindlimb above the carpus and tarsus. Study Details: For this view, the patient's nose should be perpendicular to the plate or cassette, so the nose should be pointing up at a 90 angle from the table and wrapped with tape to secure it in this position (FIGURE 8).This view needs to be collimated down to just include the top of the head (FIGURE 9). Foam positioners. Center the primary beam over the scapula (FIGURE 35) and collimate to include the entire bone and approximately one-third of the proximal humerus (FIGURE 36). As a supervising technician in practice, I was very pleased to have the opportunity to review the Handbook of Radiographic Positioning for Veterinary Technicians.The book begins with a very good overview of the principles of radiographic positioning which includes patient preparation, directional terminology, positioning aids, as well as proper collimation, measurement, and labeling requirements. As with the previous views, the patient is placed in dorsal recumbency and the forelimbs are extended caudally and secured with tape. Mediolateral view (splay toe). We entered into this profession with a passion for animals and have gained an immense knowledge of veterinary medicine, but it is our responsibility to learn more. The marker is placed on the dorsal aspect of the patient indicating recumbency. The marker should be placed on the lateral aspect of the carpus. Therefore, taking at least two orthogonal views is of critical importance when trying to get diagnostic-quality images.7 Orthogonal views are images that are taken at 90 to each other. Lead gloves should be kept on a glove rack or stored on a flat surface with round PVC pipes placed inside the liner to prevent the material from creasing in the same spot over time. The patient is positioned in lateral recumbency with the affected limb closest to the plate or cassette. Up until the 1950s, it was possible to go to a shoe store and use x-rays to determine your shoe size.1 Fortunately, the principle of being cautious about radiation has improved over the decades. Collimate to include approximately one-third of the femur and one-third of the tibia (FIGURE 8). The marker should be placed on the lateral aspect of the foot. Radiographs themselves are painless and noninvasive, but unsedated restraint can make the patient anxious, scared, and sometimes aggressive.2 This not only harms the patient, but also makes it more difficult to obtain diagnostic results in an efficient manner and can endanger team members. The terms used to describe radiographic positioning can be confusing and depend on the area being imaged. Editors Note: This article was originally published in November 2016. Personnel who work with radiation should protect themselves from all workplace radiation exposure by wearing the appropriate personal protective equipment (PPE). Again, the fabellae may or may not appear symmetric; however, the diagnostic view should show fabellae that are bisected symmetrically by the epicondyles of the femur. Imagine being in excruciating pain, scared, nervous, stressed, surrounded by strangers, and unable to communicate with anyone, all while being stretched out on a table in awkward and painful positions. Sedation is very helpful for this view, which can be painful and awkward for a nonsedated patient. The marker should be placed on the cranial aspect of the foot. The larger image depicts positioning for bulla and mandible. Rostral Caudal Open Mouth Tympanic Bullae View. Sedated patients remain still during radiographic exposures, allowing fewer retakes of the same area of interest and therefore lowering radiation doses. 1. The patient is positioned in sternal recumbency with a triangular wedge under the abdomen and pelvis. The marker should be placed on one side of the patient to indicate right or left. She stays busy these days by spending the evenings with her family on their small farm in Attica, Ind. Coverage of non-manual restraint techniques, including sandbags, tape .
