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. When it comes to taking radiographs, this means knowing the positioning techniques necessary to achieve diagnostic-quality images in a timely and efficient manner, as well as the safety precautions all staff should follow when working with radiation. She graduated from Purdue with an associates degree in veterinary technology in 2007. Palpate the elbow. The marker should be placed on the cranial aspect of the tibia (FIGURE 11). 3rd Ed. If the patient weighs <20 kg, only 0.5 to 1 inch of padding will likely be needed. In 2005, she earned a bachelors degree in English, in pursuit of her passion for reading and writing, but soon realized that something was missing from her life: her love for animals. Limited to US only. The patient is positioned in sternal recumbency. The sternum of the patient can be rotated up from the table to better visualize the entire scapula. Dog muscle anatomy poster created using vintage images. Again, the series consists of 2 views: mediolateral and caudocranial. The least risk of exposing those assisting with the examination to radiation. A heavy positioning aid can be placed under the carpus of the affected limb to push it up toward the head and hyperflex the elbow. Trainees must have a DVM, or equivalent degree. The use and care of lead protective equipment. The patient is positioned in sternal recumbency. To keep the radiation dose to a minimum for all involved, it is a good idea to keep a log of the number of times each person remains in the room during an exposure. Abduct the nonaffected limb out of the view by taping it to the table. Patient sedation can also help keep veterinary technicians healthy. The marker is placed on the dorsal aspect of the patient indicating recumbency. The forelimbs should be pulled caudally to aid in positioning the skull, and the affected side of the skull is placed closest to the plate or cassette. Clinical efficacy and safety of dexmedetomidine and buprenorphine, butorphanol or diazepam for canine hip radiography. Tape around the foot, extend the forelimb cranially, and secure it to the table. Tape around the proximal phalanges, extend the forelimb cranially, and secure it with tape to the table. Pharm. If the patient has a prominent occipital protuberance, it can be difficult to balance the head symmetrically. The forelimbs should be extended caudally and secured with tape. Without sedation, this is the situation that many veterinary patients face. The patient can be placed in sternal or lateral recumbency. A discussion of patient positioning includes the use of foam cushions, centering, collimation landmarks, labeling requirements, and additional comments in a simple bullet format for each positional view. The patient is positioned in right lateral recumbency. The marker should be placed on the lateral aspect of the foot. The forelimbs should be extended caudally and secured with tape. The terms used to describe radiographic positioning can be confusing and depend on the area being imaged. Many of the images in this article contain a magnification or calibration marker (FIGURE 1). The patients nose should be pointing upward. To optimize correct patient positioning, it is sometimes necessary to make minor positional adjustments to the head or extremities by placing small pieces of radiolucent foam under the nose or between the limbs. Tape around the tarsus of each leg, extend the hindlimbs completely, and secure the tape to the table (FIGURE 20). The difference between that angle and a perpendicular line to the mechanical axis is the tibial slope.a. 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. (VSPN Review), * Textbook Of Veterinary Physiological Chemistry: 2nd ed, * Workbook McCurnin 7th Ed. The skeletal system and joints. A marker should be placed on one side of the patient to denote the right or the left side. Today, we know that x-rays interact with cells in 4 ways2: Most states require that any person working with radiation-emitting devices wear a personal radiation exposure monitor. The patient is positioned in lateral recumbency with the affected limb closest to the plate or cassette. PPE should be inspected routinely for damage. 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. This view needs to be collimated down to just include the top of the head (FIGURE 9). 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. The goal of this view is to superimpose the wings of the ilium and hemipelvis. The head is rotated ventrally at a 45 angle, using a radiolucent wedge or foam padding to lift the mandible off the table (FIGURE 17). More information about sedation protocols can be found in the resources listed in BOX 1. These dosimeter badges, as they are often called, should be checked at least quarterly to evaluate the wearers cumulative radiation dose.3 According to the US Nuclear Regulatory Commission, occupational personnel should not receive a total effective dose of more than 5 rem per calendar year.4 There are more specific limits for skin and eyes (BOX 1). 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). Collimate to include about half of the scapula and about half of the humerus (FIGURE 29). Minimal trauma to the area of interest. Part 1 of this article, published in the November/December 2016 issue of Todays Veterinary Nurse, described radiation safety policies, personal protective equipment, and guidelines for positioning orthopedic radiography patients to obtain diagnostic-quality images of the skull, shoulders, and elbows. Regardless of the species and restraint device used, the , Study Details: WebPositioning Veterinary Patients The following positioning devices can be used to help position patients and reduce staff members exposure to radiation: Elastic tape Plastic , Url: Todaysveterinarypractice.com View Study, Study Details: WebRadiographic positioning is essential for correct identification and diagnoses of lesions on radiographs.

Small Animal Radiography: Essential Positioning Guide NAVC Media $79.95 Small Animal Radiography: Essential Positioning Guide provides both a refresher in correct patient positioning for the veterinarian and a continuing resource for the clinic's radiography staff. Two markers are placed in this view, one indicating the recumbency of the patient and the other the beam direction. Center the primary beam in the middle of the tibia (FIGURE 13) and collimate to include the stifle and the tarsus. Our veterinary anatomy posters and anatomical charts are scientifically accurate. Each of the main chapters covers an anatomical region, and begins with an overview of the diagnostic benefits of radiography of each region. X-rays differ from some other forms of electromagnetic radiation because their very short wavelength allows them to penetrate matter, including cells. The patient is positioned in lateral recumbency with the affected limb closest to the plate or cassette. When pulling the head to one side, be careful not to rotate the elbow too far medially or laterally. Medial stress view. This view superimposes the scapula over the cranial portion of the thorax and helps to better visualize the distal scapula. . There is no specific angle for the tarsus. Center the primary beam over the metacarpal bones and collimate to include the carpus and all of the phalanges (FIGURE 25). Place another piece of tape around the metacarpus, above the first piece, distal to the carpus. The marker should be placed lateral to the joint indicating which leg is being imaged. The radiographic inspection involves using a fluoroscopy or radiography unit to look for cracks in the lead.9 Common settings for this inspection are 80 kVp and 5 mAs; the settings can be adjusted based on the desired density of the material.2 Although there are no federal guidelines for determining when to replace PPE, a general rule is to take equipment out of service if cracks are found over any pertinent organs, including reproductive and endocrine organs, or if the area of the crack is larger than 5.4 cm.10 Lead should be properly disposed of according to guidelines regulated by each state. Cat anatomy poster with 6 illustrations. Regardless of the area being positioned a variety of positioning aids should be available within the practice. Again, in some cases, if the condyles are not superimposed, the cotton from the tarsus can be removed and applied under the stifle. Flex the carpus so that the phalanges almost touch the distal aspect of the radius and ulna. Pharm. Accessed September 2016. nrc.gov/images/about-nrc/radiation/dose-limits.jpg.

The position of the patient for these views depends on the level of sedation being used. Tech. 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. The tube head is angled for this view but is aimed dorsoventrally. There are many important things to keep in mind when taking radiographs, but first and foremost, it should be the duty of the veterinary technician to do what is best for the patient. The VV50 Versa-View Ultra Stand portable x-ray unit positioning aid is versatile, convenient, stable, and has a compact design, providing quick and easy mobilization in the field. To separate the phalanges, take a 0.5-inch wide piece of tape, wrap it around P2, and pull the toe cranially. Tape around the foot, extend the forelimb cranially, and secure it to the table (FIGURE 26). Hold the patients elbow in place with a lead-gloved hand and gently press the spoon laterally to stress the lateral joint of the carpus (FIGURE 35). Milan Kundera said, Humanitys true moral testconsists of its attitude towards those who are at its mercy: animals.1 The oath for veterinary technicians states, I solemnly dedicate myself to aiding animals and society by providing excellent care and services for animals, by alleviating animal suffering Once in practice, it is important to remember this oath.

To isolate the opposite arcade (the left maxilla), a VDRL view would be needed. D ental x-ray units (FIGURE 1) are most commonly purchased and used to produce dental radiographs.These units are portable or wall mounted. One of the standards we follow at Purdue is to perform a complete radiographic series, no matter what is being imaged. 6 years and is PennHIP certified. Center the primary beam over the metacarpals and collimate to include the carpus and all of the phalanges (FIGURE 32). The marker should be placed on the cranial aspect of the foot. For example, VDLR means the beam is traveling ventrodorsally from the left side of the patient to the right side (FIGURE 19). It should be possible to visualize the bullae without the mandible or maxilla superimposed over them. Cotton or radiolucent material can be placed under the cervical region around C1C3 to help extend the spine and straighten the head if needed (FIGURE 4). Inspections should include a visual and radiographic assessment. This can be achieved by using a positioning device to prop the patients head to the lateral side or, if needed, having a team member in PPE hold the head out of the primary beam. The patient is positioned in dorsal recumbency. The marker should be placed lateral to the joint indicating which leg is being imaged. Understand the musculoskeletal, nervous and internal organ systems easily with these wall hangings in lamination or paper. The exact level of radiation exposure that causes cell death is not known, so all exposure should be treated as if it is going to produce cell death.
