When taking lateral thoracic views on either dogs or cats, it is important to center the x-ray beam on the caudal aspect of the scapula, and pull the front legs forward, off the cranial thorax. It is important not to stretch the patient, as this results in distortion of the thorax Barrel-chested dogs typically have cardiac silhouettes measuring closer to 3.5 intercostal spaces due to the more horizontal position of the heart. The cardiac silhouette occupies approximately 70 percent of the distance from the sternum to the thoracic spine on lateral radiographs
The following radiographs are the left lateral, right lateral and ventrodorsal views of the thorax of a ten-year-old Mixed Breed Dog. Metallic hemoclips are present in the cranial abdomen. College of Veterinary Medicine • copyright 201 Abstract Selected structures seen on right and left lateral thoracic radiographs of 12 dogs were evaluated for differences in position, size, and shape. The size and position of the cardiac silhouette were different when thoracic radiographs made in left and right lateral recumbency were compared
In dogs and cats, elbow and antebrachial radiographs are used to evaluate: • Traumatic injuries • Soft tissue swelling • Any potential cause of a thoracic limb lameness A dog is lying in left lateral recumbency for a pelvis radiograph. The right femur will be? When taking a lateral thoracic radiograph, you should make sure the spine and sternum are. Equidistant from the table. When taking a VD thoracic radiograph, you should measure at the level of For a VD thoracic radiograph, the dog is positioned in dorsal recumbency with its forelimbs extended as far cranially as possible and the hindlimbs pulled caudally. The beam should be centered over the thorax and collimated appropriately. A DV view is dorsoventral The veterinarian was instructed to obtain thoracic radiographs during peak inspiration with the dog in right (RLR) and left lateral recumbency (LLR), the images marked with the recumbent side. The thoracic limbs should be pulled as cranially as possible in order to minimise superimposition with the cranial thorax The study measured VLAS as described by P aper 1 and performed the measurement on right lateral thoracic radiographs. Dogs used in the study were defined as healthy based on history, radiography and echocardiography (the dogs had a LA:AoSx ration of <1.6). The study population was made up of 80 dogs
Measurement and positioning of a canine for a right lateral thoracic radiograph Right inspiratory lateral thoracic radiograph of a 6 year old mixed breed, intact male dog (BCS 5/9) showing alveolar patterns (A). The alveolar pattern is described as having cottony radiopaque. Thoracic Radiographs DV. Right Lateral. One of the primary things one would like to evaluate on this dog is its lung fields for the presence of pulmonary edema. Unfortunately, this dog's diaphragm is displaced forward by its ascites making it impossible to tell if there are infiltrates in the caudodorsal lung fields Dogs with shallow, wide thoracic conformation have a short, round cardiac silhouette that, on the lateral radiograph, has a marked cranial inclination and a long area of sternal contact. On the Ventro-Dorsal view or Dorso-Ventral radiograph, the cardiac apex usually is located to the left of the midline and is often more difficult to identify. The radiography of the chest makes use of a minimum three views for correct assessment- lateral (LL) - left and right and ventrodorsal / dorsoventral (VD/DV). All foreign bodies are removed in the radiographic examination - leash, neckpiece, bandages, dirt, water, blood. The patient must be immobilized to the limit
The Cardiovascular System. As coughing in the dog could potentially be caused by cardiac disease, the cardiac silhouette demands attention in the thoracic radiograph. In the coughing dog the size of the left atrium has to be evaluated. An enlargement of the left atrium leads to a dorsal and eventual compression of the left stem bronchus In this module of the animal atlas vet-Anatomy is displayed the cross-sectional labeled anatomy canine thorax on a Computed Tomography (CT) and on 3D images of the thorax of the dog. CT images are available in 3 different planes (transverse, sagittal and dorsal) with two kinds of contrast (bones/lungs and soft tissues/mediastinum/vessels) Fig. 1: Lateral thoracic radiograph of a dog with a diaphragmatic hernia and several loops of bowel in the thoracic cavity. Hydrothorax may be the only radiographic sign if the liver is the only organ herniated into the thorax. This fluid appears serosanguineous and is a transudate or modified transudate. Ultrasonographic examination of the. Radiography remains a simple and highly effective diagnostic tool, and obtaining radiographs should be quicker than waiting for your blood samples to be analysed in-house. Sedation is really helpful. Routinely lightly sedating dogs and cats for radiographic procedures (particularly abdomen and thorax) will vastly improve the quality of your study Measurement from a lateral projection is recommended, if possible. The reference values for vertebral heart scale measured on VD and DV radiographs are 9.4-11.0 and 8.8-11.7, respectively, for dogs. 11. The published range for a normal VHS is 9.2-10.3 on a lateral radiograph, with 10.5 suggested as the cutoff for clinical determination of.
A ventrodorsal and a right lateral thoracic radiograph illustrate pulmonary metastatic disease in a 14-year-old spayed German shepherd dog with splenic hemangiosarcoma. There are multifocal-to-coalescing and, in some places, miliary patterns of small round soft tissue nodules throughout all lung fields (arrows) vessels is more common in dogs with heartworm disease. Enlargement of both the pulmonary artery and vein may indicate fluid overload, or the presence of a left-to-right shunting congenital cardiac defect. Lung patterns Radiographic patterns that may be detected upon thoracic radiography include bronchial, interstitial, alveolar and vascular What's Your Radiographic Diagnosis? E. A. Riedesel, DVM, DACVR* Fig. 1: Right lateral and dorsoventral thoracic radiographs of 11 year old, male collie with an enlarging facial mass. History An eleven yearold, male, collie presented for evaluation of a right facial mass. The mass was located rostroventrally to the right eye. The second variation of normal is a triangular pocket of air in the thoracic esophagus, just cranial to the heart base. Finally, if you are taking three-view thoracic series (a very good idea for diagnosing metastases and pneumonia), you'll often see some fluid in the caudal esophagus on the left lateral projection (image 2)
of radiographic lung patterns in EBP are lacking. The aim of this retrospective case series study, therefore, was to evaluate the radiographic pattern and its topographical distribution in a series of dogs with a confirmed diagnosis of EBP.

The mediastinal haematoma can be seen as an irregular soft tissue mass filling out the cranial and caudoventral mediastinum This useful webinar recording takes us through exactly how to describe and interpret different lung patterns in thoracic radiographs in cats and dogs. Dr Jones begins by describing the anatomy of the lung lobes as seen on thoracic radiographs in lateral and dorso-ventral views Based on MRI, dorsal, and dorso-lateral hemivertebrae were the cause of spinal cord compression in 5/12 (41.6%) of dogs with neurologic deficits. Findings indicated that a modified human radiographic classification system of vertebral malformations is feasible for use in future studies of brachycephalic screw-tailed dogs The radiographic features of aortic bulb/valve mineralization in 20 dogs were reviewed. Extent, shape, number, and location of mineralization were recorded. Five of the dogs had additional alternate imaging examinations, including bone scintigraphy, echocardiography, and thoracic computed tomography. A necropsy was done on one dog, and the area.
This is a lateral view of the thorax of a dog, illustrating the measurement of a vertebral heart scale. Developed in 1995, this method assesses cardiac size in dogs using anatomical landmarks. 9 These authors showed that cardiac size could be reliably assessed on lateral thoracic radiographs by comparing the sum of 2 linear measurements (the lengths of the long and short axes of the heart. Dogs not uncommonly develop eosinophilic bronchopathy (bronchitis) as evidenced by a marked bronchointerstitial pattern and a large number (often in excess of 20,000) of circulating eosinophils. Cats are often affected with asthma or chronic bronchitis. Due to difficulty during expiration, thoracic radiographs will also commonl Evaluation of the thoracic radiographs of individual dogs was performed over a negathoscope. The latero-lateral thoracic radiographs were categorized based from the descriptions of Rudorf et al. (2008) (entry-exit points of the X-ray beam on the dog's body and the respiratory phase when the radiograph was taken) The thoracic radiograph provides information about thoracic musculoskeletal conformation and disease, cardiac size and shape, pulmonary parenchymal and vascular disorders, and conditions involving the pleura, mediastinum, esophagus, and diaphragm. Radiographs help confirm or exclude clinical.

Pectus excavatum, thoracic spine deformities, tracheal hypoplasia and lateral heart displacement are frequently described in brachycephalic dog breeds. Pectus carinatum is described sporadically, although the authors' observations demonstrate that it may occur in certain brachycephalic dog breeds. It was hypothesised that dogs of screw-tailed brachycephalic breeds carry a greater risk of these. Dogs with pulmonary hypertension or radiographic changes compatible with left sided congestive failure were also excluded. All radiographic measurements were obtained by the same observer (XS) using Microsoft Office Power point 2007 (Microsoft Corporation, USA) in a digital latero-lateral thoracic radiograph with the dog in right lateral. To determine whether subcutaneous fat thickness measured on thoracic radiographs was associated with body condition score (BCS) in dogs.87 client-owned dogs (41 males and 46 females) with a median age of 10.0 years (range, 1 to 16 years) and median weight.
PROCEDURES For each dog, 3-view thoracic radiographs were obtained within 24 hours of an echocardiographic examination. The VLAS was measured on right and left lateral thoracic radiographs and compared with the left atrium-to-aortic root ratio acquired from short-axis (LA:AoSx) and long-axis (LA:AoLx) echocardiographic images Lateral thoracic radiographs of dogs presented with coughing were assessed to determine abnormalities in selected thoracic structures. Thirty radiographic images were used to describe tracheal diameter and thoracic inlet ratio (TD:TI), pulmonary patterns present, cardiac silhouette abnormalities and vertebral heart size (VHS) Dog positioned for lateral projection of the tho-racic spine (A) and corresponding radiograph (B).

ANIMALS: 30 dogs with endoscopically confirmed spirocercosis. PROCEDURES: Dorsoventral (DV) and right lateral recumbent (RLR) thoracic survey radiographs were obtained for each dog. Endoscopy was subsequently performed, the esophagus was inflated with air, and left lateral recumbent, RLR, DV, and ventrodorsal thoracic radiographs were obtained Key words: cardiomegaly, dog, Greyhounds, heart, thoracic radiology, VHS. Introduction C ARDIAC SIZE CAN be quantiﬁed from lateral thoracic radiographs using the vertebral heart size (VHS), as proposed by Buchanan and Bucheler.1 In clinical practice, a VHS above the reference range on lateral thoracic radio When it comes to obtaining thoracic radiographs of coughing dogs, diagnostic imaging specialist Dr. Rachel Pollard has tips for improving your image. Including both lateral projections is the most comprehensive way to check for lesions, and the left lateral projection, in particular, aids in the the detection of pulmonary nodules and. In all dogs the pulmonary abnormalities were present in more than one lung lobe. In 1 dog pulmonary interpreta-tion was hampered by superimposition of fluid but at n cropsy the lungs proved to be normal. Figure 1. Lateral (a) and ventrodprsal thoracic radiographs (13). Mild pleural effusion is present. The right cardiac lung lobe is.
The Imaging Anatomy web site is a basic atlas of normal imaging anatomy of domestic animals. It is designed as an aid for veterinary students beginning their study of diagnostic imaging. It is not meant to be a comprehensive reference of imaging anatomy.

As a result, for adequate thoracic radiography a powerful, high-milliamperage X-ray machine is required. A routine survey radiographic examination of the thoracic cavity includes at least one lateral and one dorsoventral re A thoracic (chest) radiograph (X-ray) is a procedure that allows your veterinarian to visualize tissues, organs and bones that lie beneath the skin of the chest cavity in a dog or other animal. Thoracic radiographs are recommended for any pet with difficultly breathing or with suspicion of heart disease or lung disease Science; Anatomy and Physiology; Anatomy and Physiology questions and answers; Any of the following is an indication of full inspiration sign in a lateral thoracic radiograph in dogs: : (1 Point) Increased separation of heart and diaphragm, Increased dorsal argutation of trachea Extension of the right cranial lung lobe to first rib Diaphragmatic crura is caudal to T13 All of the listed are correc
Right lateral thoracic radiograph of a dog with stage B2 MMVD: 'V shape' from emergence of left and right caudal mainstem bronchus post carina has disappeared (compared to previous radiographs where the V shape was visible) Instead, post carina, only a very narrow channel is observed, which ends prior to the caudal border of the heart silhoutte These findings suggest that radiographic liver length is a reliable measurement for estimating liver volume in dogs and that it is not influenced by thoracic conformation. For 60 of the 65 dogs, a method of assessment of liver volume was formulated that required 2 measurements to be made on the lateral abdominal radiograph and 1 to be made on.

Measurement of the P:R ratio in the same dog Dogs with fungal discospondylitis may require The complete blood count and serum biochemical profile were within normal limits. Radiography of the thoracic and lumbar spine revealed vertebral body endplates that were irregular, with permeative lysis centered at the disc space of T10 to T11, T13 to L1, L1 to L2, and the lumbosacral junction. From the results (TABLE I), the mean radiographic cardiac index was 0.64±0.01 in DV views and 0.67±0.01for VD radiographs. In lateral views (TABLE II), location of heart can easily be used to evaluate cardiac enlargement in thoracic radiographs (16, 17). This is because an enlarged or globoi
