Male body cavity, reproductive organs, heart, liver and 24" X 36" (Laminated) A V trough or other positioning device should be used to ensure the patient is as straight as possible (FIGURE 27). (VSPN Review), * Textbook Of Veterinary Physiological Chemistry: 2nd ed, * Workbook McCurnin 7th Ed. The following tutorial includes positioning instructions to obtain two orthogonal views for the skull, shoulders, and elbows. 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. Sometimes, however, we can get caught between doing what is best for the patient and working with limited monetary resources and time constraints. I would highly recommend this book for veterinary practices or veterinary technician students as a reference for proper radiographic positioning. To separate the phalanges, place some cotton between each toe (FIGURE 31). We respect your privacy and promise not to spam you. Each Acupressure poster measures 12" x 18" colorful Meridian diagram is laminated for durability. Editors Note: This article was originally published in November 2016. Lead, being a very dense material, is the approved barrier against harmful scatter radiation. 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). 2. To separate the phalanges, take a 0.5-inch wide piece of tape, wrap it around P2, and pull the toe cranially. Combination of essential positioning devices designed to replace your hands, with attention to patient comfort. Sedated patients remain still during radiographic exposures, allowing fewer retakes of the same area of interest and therefore lowering radiation doses. Positioning for this view is very similar to the frontal sinus view. Shoe-fitting fluoroscope (ca. Scatter radiation, or secondary radiation, poses exposure risks to radiography personnel.2. 1930-1940). Using this marker allows the veterinary team to adjust for magnification by calibrating the radiograph with a known value: the size of the metal ball at the end of the flexible arm. Residency Training Programs are available at universities or in private practice and are intended to lead to board certification by the ACVR in either Radiology or Radiation Oncology. 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. If the elbows are rotated, tape around them and pull in either direction to ensure that they point straight up. Three types of restraint are used for avian and exotic patients during radiography: (1) manual, (2) physical, and (3) chemical. While working at a private practice, she was introduced to the role of veterinary technician. 2. The marker should be placed on the lateral aspect of the tibia (FIGURE 14). If you click a merchant link and buy a product or service on their website, we may be paid a fee by the merchant. The skeletal system and joints. The goal of this view is to superimpose the condyles of the femur. 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. Lateral skull Lateral thorax This view needs to be collimated down to just include the top of the head (FIGURE 9). Center the primary beam over the flexed carpus and collimate to include approximately one-third of the radius and ulna and one-third of the metacarpus (FIGURE 38). I was very pleased with the number of views (including some less common views) covered in this text, as well as the comprehensive number of photographs and diagrams included. Providing the most information we can to obtain the best possible diagnosis or outcome for the patient is our primary goal! While working at a private practice, she was introduced to the role of veterinary technician. The marker should be placed cranial to the joint indicating which leg is being imaged (FIGURE 26). In any radiographic study, especially digital studies, magnification resulting from patient size and exposure technique can be an issue. 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). Center the primary beam over the pelvis and palpate the wings of the ilium as the cranial landmark and the caudal border of the ischium as the caudal landmark. 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. Markers should always be placed to indicate patient position and/or beam direction. 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. Handbook of Radiographic Positioning for Veterinary Technicians, Margi Sirois, EdD, MS, RVT; Elaine Anthony, MA, CVT; Danielle Mauragis, CVT, * Appl. In this first of two articles on radiographic positioning, we provide an overview of the principles and guidelines of radiation safety in the workplace as well as the techniques used to obtain good-quality orthopedic radiographs of the skull, shoulders, and elbows with great efficiency and care for the patient. A survey of more than 1200 NAVTA members found that sedation reduced the risk of on-the-job injuries, with 83% of respondents reported being injured while physically restraining a cat or dog, while only 9% reported being injured by a sedated animal. Lead gowns should be inspected annually, at minimum. 3rd Ed. . aMark Rochat, DVM, MS, DACVS, Clinical Professor and Chief of Small Animal Surgery. Mediolateral view (splay toe). The patient is positioned in lateral recumbency with the affected limb closest to the plate or cassette. 410 IAC 5-6.1: X-rays in the healing arts. Press the edge of a wooden spoon or similar radiolucent device on the medial aspect of the carpus, near the middle carpal joint. Clinical Laboratory Animal Medicine: An Introduction, 4th Ed (VSPN), Clinical Pathology & Laboratory Techniques for Veterinary Technicians (VSPN), Clinical Veterinary Advisor: Dogs and Cats, 2nd Ed, Dermatology for the Small Animal Practitioner (VSPN Review), Diagnostic Imaging of Exotic Pets: Birds, Small Mammals, Reptiles, Digital Radiography for the Veterinary Technician, 1st Ed. Again, in some cases, if the condyles are not superimposed, the cotton from the tarsus can be removed and applied under the stifle. If the patient is not heavily sedated, a staff member wearing the required PPE may be needed to restrain the patients head. When describing the way the beam enters and exits the limb distal to the carpus and tarsus, it is appropriate to use the terms dorsopalmar and palmarodorsal for forelimbs or dorsoplantar and plantarodorsal for hindlimbs. The skeletal system and joints. 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. Abduct the nonaffected limb out of the view by taping it to the table. These units often have fixed or preset peak kilovoltage (kVp) and milliamperage-seconds (mAs) and a variable exposure time. Depending on the patient position, the head is rotated in an oblique position as close to 45 as possible, with the affected mandibular arcade closest to the table (FIGURE 20). You may have to palpate the patella to find the center. This concise reference presents a systematic approach to the positioning of canine, feline, and exotic animal patients for routine and special radiographic procedures. This view of the pelvis is considered the most diagnostic view. One of the standards we follow at Purdue is to perform a complete radiographic series, no matter what is being imaged. To get the forelimb in a straight craniocaudal position, the patients head and body may need to be rotated left to right (FIGURE 27). Tape is applied behind the maxillary canine teeth to pull the nose 10 to 15 cranially (FIGURE 6). The patient is positioned in sternal recumbency with a triangular wedge under the abdomen and pelvis. This discomfort requires the team to work slowly and cautiously while positioning. (FIGURE 4) Similarly, the thickness of the padding under the pelvis may need to be increased or decreased to superimpose the condyles. 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. Human teeth for comparison. 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. Copyright 2023 Today's Veterinary Nurse Web DesignbyPHOS Creative. Center the primary beam over the tibia and collimate to include the stifle and the tarsus (FIGURE 17). The tube head is angled for this view but is aimed dorsoventrally. Rostral Caudal Open Mouth Tympanic Bullae View. Press the edge of a wooden spoon or similar radiolucent device on the lateral aspect of the carpus, near the middle carpal joint. Limited to US only. Place tape around the carpus of the affected limb and pull the limb forward in a natural position. Tech. Other factors that can help in minimizing radiation exposure include using proper exposure techniques from a professionally developed technique chart, sedation for patients that are in pain or anxious, and positioning aids. 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. Tape around the tarsus of each leg, extend the hindlimbs completely, and secure the tape to the table (FIGURE 20). Center the beam over the axillary joint space of the leg of interest (FIGURE 28). Choose from a large selection of topics on Canine, Feline, Equine, and Bovine anatomy. This position helps to isolate one side of the mandible by avoiding superimposition of the opposite dental arcade. Pull it laterally and secure it to the table. The patient is positioned in lateral recumbency with the affected limb closest to the plate or cassette. Practicing radiographic positioning on our models is easy and helps build staff confidence in proper technique and . Without sedation, this is the situation that many veterinary patients face. The marker should be placed on the lateral aspect of the foot. The femurs should be parallel to the x-ray table 4.
