There is a very brief discussion of the parallel and bisecting angle techniques, followed by great black-and-white photographs and radiographs of all standard positions needed in the canine and feline using a dental radiographic unit. 5. X-rays differ from some other forms of electromagnetic radiation because their very short wavelength allows them to penetrate matter, including cells. If the clinician prefers, all the phalanges can be included in this view. If possible, the marker should be placed cranial to the joint indicating which leg is being imaged. 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. The patient is positioned in lateral recumbency with the affected limb closest to the plate or cassette. A marker should be placed on one side of the patient to denote the right or the left side. Use some cotton or a radiolucent wedge under the tarsus to aid in superimposing the femoral condyles. Accessed November 2016. It is suggested (but unfortunately not required) that all personnel working with radiation-emitting devices wear a 0.25- to 0.50-mm lead apron or wrap, lead thyroid shield, lead gloves, and even lead-lined goggles.6 These guidelines can vary by state, but most states have adopted the minimum of 0.25-mm lead equivalent.7,8.

For example, VDLR means the beam is traveling ventrodorsally from the left side of the patient to the right side (FIGURE 19). The patient is positioned in sternal recumbency with a triangular wedge under the abdomen and pelvis. As with the regular craniocaudal view, the head and body of the patient may need to be rotated left to right to get the forelimb in a straight craniocaudal position, using a positioning device or a team member wearing PPE. For example, DVLR means the beam is traveling dorsoventrally from the left side of the patient to the right side. 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. (FIGURE 4) Similarly, the thickness of the padding under the pelvis may need to be increased or decreased to superimpose the condyles. 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. Dog muscle anatomy poster created using vintage images. This initiative was created to promote radiation safety awareness in the veterinary workplace with the goal of reducing occupational radiation exposure of veterinary personnel through a combination of 'hands-free' techniques workshop, innovative restraint devices and industry educational resources.

Trainees must have a DVM, or equivalent degree. Written by a veterinary technician for practicing vet techs and students, this new edition offers a complete, practical guide to producing consistently superior radiographic images. The marker should be placed on one side of the patient to indicate right or left. The marker should be placed cranial to the joint indicating which leg is being imaged (FIGURE 26). Artificial intelligence is quite a buzzword these days, with AI technology increasingly being applied to all aspects of information technology, affecting every corner of our day-to-day lives. 1. If the patient weighs <20 kg, only 0.5 to 1 inch of padding will likely be needed. This view needs to be collimated down to just include the top of the head (FIGURE 9). 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. Accessed September 2016. The marker should be placed on one side of the patient to indicate right or left (FIGURE 10). In her spare time, Jeannine enjoys reading, writing, cooking, and spending time with her husband, son, two dogs, and adopted blood donor cat. Some states have laws against anyone being in the room during an exposure. Collimate to include approximately one-third of the femur and one-third of the tibia (FIGURE 8). The position of the patient for these views depends on the level of sedation being used. 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. Secure this limb with tape or another positioning device. The view must include the entire head from the base of the skull to the tip of the nose (FIGURE 5). The goal of veterinary radiology is to safely and efficiently produce diagnostic images.1 Therefore, it is essential that veterinary technicians think critically about patient anatomy and positioning, radiological standards, and proper radiographic technique in order to effectively and consistently produce diagnostic radiographs. (VSPN Review), Veterinary Hematology A Diagnostic Guide and Color Atlas (VSPN), Veterinary Technicians Daily Reference Guide: Canine and Feline (VSPN), Veterinary Technicians Large Animal Daily Reference Guide (VSPN), Writing the Research Paper A Handbook, 8th Ed, * Appl. However, different states may have different guidelines. Several commercially available devices can be used to aid in positioning, such as V troughs, sandbags, cotton, tape, radiolucent blocks and wedges made of foam, and immobilization blocks5 (BOX 2). The terms used to describe radiographic positioning can be confusing and depend on the area being imaged. In any radiographic study, especially digital studies, magnification resulting from patient size and exposure technique can be an issue. If a V trough is not available, sandbags or lead blocks can be placed near the shoulders to prop up the patient. Press the edge of a wooden spoon or similar radiolucent device on the medial aspect of the carpus, near the middle carpal joint. The marker should be placed on the cranial aspect of the tibia.

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. Tape around the metatarsus of the affected limb and completely extend the leg and tape it to the table (FIGURES 6 and 7). The femurs should be parallel to the x-ray table 4. Use some cotton or a radiolucent wedge under the tarsus to aid in superimposing the femoral condyles (FIGURE 16). Angle x-ray beam 20 from perpendicular (if possible). Center the beam between the eyes just under the frontal sinus. ORAU. 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. Mechanical restraint, or the use of positioning aids and devices, can be used in conjunction with chemical and/or manual restraint. In her spare time, Jeannine enjoys reading, writing, cooking, and spending time with her husband, son, two dogs, and adopted blood donor cat. We undergo a comprehensive evaluation by the American Board of Veterinary Specialties, a committee of the AVMA, to ensure we are maintaining the required .
