In some cases, I feel that this text may simply remind some readers of many useful, but less common (or forgotten) radiographic positioning techniques as well as tips for improving the common views. Tape is applied behind the maxillary canine teeth to pull the nose 10 to 15 cranially (FIGURE 6). More information about sedation protocols can be found in the resources listed in BOX 1. 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). Abduct the nonaffected limb out of the view and tape it to the table (FIGURE 15). However, different states may have different guidelines. Similarly, the padding under the pelvis may need to be increased or decreased to superimpose the condyles. We will continue this discussion in part 2. To learn more about your states radiation guidelines, go to crcpd.org, and click on Radiation Control Programs on the left-hand side to follow the links to the full map, find your state, and go to the correct website. The goal of this view is to superimpose the mandibular rami, so it is essential to place some cotton padding or a radiolucent wedge under the mandible. Choose from a large selection of topics on Canine, Feline, Equine, and Bovine anatomy.

ORAU. The marker should be placed on the lateral aspect of the carpus. When positioning patients for radiographic studies, patient comfort should always be a priority, and injured or suffering patients should be made as comfortable as possible with analgesics or sedation. It is the responsibility of the practice and the team members to be aware of and follow state regulations on physical and manual restraint. The field of view can be collimated to include only the maxilla from the tip of the nose to the ear or to include the entire skull, depending on the clinicians preference (FIGURE 18). Press the edge of a wooden spoon or similar radiolucent device on the lateral aspect of the carpus, near the middle carpal joint. (VSPN Review), BSAVA Textbook of Veterinary Nursing, 5th ed (VSPN). Is the patient ID information correct on the image or file? As with the previous views, the patient is placed in dorsal recumbency and the forelimbs are extended caudally and secured with tape. Center the primary beam in the middle of the tibia (FIGURE 13) and collimate to include the stifle and the tarsus. The wall chart shows the skeletal structure of the cat. When manual restraint is needed, the minimum number of people needed to position and restrain the patient without compromising the safety of patient and other personnel should be in the room. Patient sedation can also help keep veterinary technicians healthy. The patient is positioned in lateral recumbency with the affected limb closest to the plate or cassette. The terms caudocranial and craniocaudal are used to describe the way the beam enters and exits a forelimb or hindlimb. It is essential to keep in mind that patients undergoing orthopedic radiography are more likely to be in pain due to a recent traumatic event or chronic condition. Radiopaque substances (e.g., metals) absorb more x-rays than tissue or bone and appear white on radiographs.6 At Purdue, we often use both radiolucent and radiopaque positioning aids. It should be possible to visualize the bullae without the mandible or maxilla superimposed over them. The femurs should be parallel to the x-ray table 4. Center the primary beam over the extended carpus and collimate to include approximately one-third of the radius and ulna and one-third of the metacarpus (FIGURE 40). Philadelphia, PA: Elsevier Saunders; 2014. The maxilla should be centered on the plate or cassette, and the field of view should include the rostral maxilla to the pharynx region or to C2 (FIGURE 16). Hyperflexion. The marker should be placed on one side of the patient to indicate right or left. To separate the phalanges, take a 0.5-inch wide piece of tape, wrap it around P2, and pull the toe cranially. Therefore, taking at least two orthogonal views is of critical importance when trying to get diagnostic-quality images.11 Orthogonal views are images that are taken at 90 to each other.

A V trough or other positioning device should be used to ensure the patient is as straight as possible (FIGURE 27). One month after graduation, Jeannine accepted a position at Purdue University as a Versatech, a position created to fill gaps in various departments all over the hospital, including diagnostic imaging. Although certain circumstances (e.g., patient stability) may allow only one radiographic image to be obtained, it is possible to miss metastasis, disease processes, or even fractures based on a single radiograph. Place a foam wedge between the hindlimbs and use the wedge to push the right hindlimb cranially (FIGURE 18). Accessed September 2016. orau.org/ptp/collection/shoefittingfluor/shoe.htm. 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. Flex the carpus so that the phalanges almost touch the distal aspect of the radius and ulna. Two markers are placed in this view, one indicating the recumbency of the patient and the other the beam direction. Three types of restraint are used for avian and exotic patients during radiography: (1) manual, (2) physical, and (3) chemical. The marker is placed on the dorsal aspect of the patient indicating recumbency. Muir WW, Bednarski RM, Hubbell JAE, Lerche P. Chemical restraint reduces patient pain and anxiety. To prevent injury resulting from the patient jumping off the table, the minimum number of people performing restraint is usually two: one person to restrain the head and forelimbs, and one person to restrain the hind portion. I see a friend. aMark Rochat, DVM, MS, DACVS, Clinical Professor and Chief of Small Animal Surgery. Lead gowns should be inspected annually, at minimum. The rat is placed on the cassette in right lateral recumbency. Place tape around the carpus of the affected limb and pull the limb forward in a natural position. Editors Note: This article was originally published in March 2017. The olecranon should remain centered between the medial and lateral epicondyles of the humerus. The ball should be positioned next to the bone or joint being imaged and appears in the resulting radiograph as a radiopaque or bright circle. Dorsopalmar view. Depending on the part of the body being imaged, this may include a mediolateral or lateromedial view, a caudocranial or craniocaudal view, a dorsoventral or ventrodorsal view, and even some oblique views. Lateral view of the skull with details of the teeth. For the most recent peer-reviewed content, see our issue archive. For this view, it is necessary to include the entire tibia, from the stifle to the tarsus, to calculate the slope of the tibial plateau. The patient is positioned in lateral recumbency with the affected limb closest to the plate or cassette. Center the beam over the axillary joint space of the leg of interest (FIGURE 28). The marker should be placed on the cranial aspect of the foot. Extend the head and neck slightly dorsal so that they are out of the view. 4th Ed. Liane has produced and launched a digital radiography positioning guide for small animals, large animals, and exotics. The tail is extended caudally and taped if necessary (Figures 1-1 to 1-3 ). Dog muscle anatomy poster created using vintage images. Hold the elbow of the patient in place with a lead-gloved hand, and gently press the spoon medially to stress the medial joint of the carpus (FIGURE 33). If such an aid is not available, tape around the affected carpus, pull the carpus cranially under the head, and secure the tape to the table (FIGURE 42). Chemical restraint has contributed greatly to the progress made in radiology by allowing positioning that would otherwise be impossible to achieve.2 Several types of sedation protocols can be used for patients, depending on the case (e.g., trauma, pediatric, geriatric). Lavin LM. 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).

She hopes to combine her love for animals and writing in the future to pursue a career in journalism for the veterinary medicine profession. These markers are primarily used in orthopedic views and are designed for use with digital hardware templates to allow surgeons to determine the exact size of the patients bone. Without sedation, this is the situation that many veterinary patients face. 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). Padding may need to be added under the elbow to position the scapula in true lateral (FIGURE 31). The below tutorial includes positioning instructions to obtain two orthogonal views for the stifles, pelvis, and lower extremities. The following tutorial includes positioning instructions to obtain two orthogonal views for the skull, shoulders, and elbows. Secure the tape.
