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. Therefore, start by placing 1 to 2 inches of padding under the patients pelvis to aid in rolling the stifle down toward the table to be parallel with the table (FIGURE 2). This short course is designed to present an overview of veterinary nuclear medicine, and how to utilize and interpret various scintigraphic studies Involvement of an ACVR radiologist and radiation oncologist in the diagnostic imaging and radiation therapy planning of your pet assures optimal care.

Again, in some cases, if the condyles are not superimposed, the cotton from the tarsus can be removed and applied under the stifle. Choose from a large selection of topics on Canine, Feline, Equine, and Bovine anatomy. Although we have advanced in many other ways, the production of x-rays remains the same as when they were first discovered: accelerated electrons interact with a metal target on the anode in the x-ray tube head, heating the target and causing photons to be produced. As a supervising technician in practice, I was very pleased to have the opportunity to review the Handbook of Radiographic Positioning for Veterinary Technicians. Digestive organs, salivary glands and lungs. 6 years and is PennHIP certified. 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 chapter on avian and exotic positioning includes a brief section on restraint techniques, followed by common radiographic positions for snakes, birds, lizards, turtles, and ferrets. Publisher: Delmar Cengage Learning (2010). The marker should be placed lateral to the joint indicating which leg is being imaged. The rat is placed on the cassette in right lateral recumbency. Similarly, the padding under the pelvis may need to be increased or decreased to superimpose the condyles.

For example, when imaging a stifle, as described below, we use a radiopaque board under the pelvis, radiolucent cotton under the tarsus, and radiolucent tape around the opposing limb. I see a friend. Non coated, coated, and closed cell foam products are not claw or teeth proof. The patient is positioned in dorsal recumbency. What are your findings? (FIGURE 4) Similarly, the thickness of the padding under the pelvis may need to be increased or decreased to superimpose the condyles. The following advantages of adequate sedation help the veterinary team achieve diagnostic-quality radiographs with minimal to no harm to the patient, greatly reducing the possibility of an inaccurate or inconclusive diagnosis: Although chemical restraint is the preferred option for orthopedic radiography, not all patients are medically stable enough to undergo heavy sedation. Take another 0.5-inch wide piece of tape, wrap it around P5, and pull caudally (FIGURE 29). Several important factors must be considered if an accurate reproduction is to be made: 1. This will help to visualize the toes individually on the radiograph. If the condyles are not superimposed, alter the padding under the tarsus, stifle, or pelvis as needed to superimpose them. 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). If the clinician prefers, all the phalanges can be included in this view. If the patient is not heavily sedated, a staff member wearing the required PPE may be needed to restrain the patients head.

Mediolateral view. The marker should be placed on one side of the patient to indicate right or left. If this does not work, place a piece of tape around the metacarpus, pull cranially, and secure it to the table. 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. Press the edge of a wooden spoon or similar radiolucent device on the lateral aspect of the carpus, near the middle carpal joint. A V trough or other positioning device should be used to ensure the patient is as straight as possible (FIGURE 27). Sedated patients should always be appropriately maintained with oxygen and monitoring. Guide to increasing the heath and life of your feline friend.

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. Place a foam wedge between the hindlimbs and use the wedge to push the right hindlimb cranially (FIGURE 18). 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. Tape around the tarsus of each leg, extend the hindlimbs completely, and secure the tape to the table (FIGURE 20). Foam positioners. The position of the patient for these views depends on the level of sedation being used. Male body cavity, reproductive organs, heart, liver and 24" X 36" (Laminated)

Tape around the proximal phalanges, extend the forelimb cranially, and secure it with tape to the table. Center the primary beam over the tibia and collimate to include the stifle and the tarsus (FIGURE 17). It is essential to understand how to acquire correctly positioned orthogonal radiographs and how positioning results in the projected image. 5th ed. Medial stress view.

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). 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. The forelimbs should be extended caudally and secured with tape. 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. In this inefficient process, 1% of the electrons energy is converted to x-rays and 99% to heat (or waste).

All veterinary professionals should practice simple methods of keeping exposure as low as reasonably achievable (ALARA), such as increasing distance from the tube head, using short exposure times, and using their knowledge and understanding of positioning to decrease the number of retakes. The marker should be placed lateral to the joint indicating which leg is being imaged. In some cases, if the condyles are not superimposed, the cotton under the tarsus can be removed and placed under the stifle. Accessed November 2016.
