The acquisition of thoracic radiographs is common in small animal practice but is less common in the horse. Computed tomography (CT) is very useful for characterizing intrathoracic disease in dogs and cats but is not used for thoracic imaging in horses. Magnetic resonance imaging is used rarely in veterinary medicine for assessing the thorax Thoracic radiographs of various dog breeds This section provides a web based overview of various normal dogs from a variety of dog breeds. Almost all 71 dog breeds currently represented have at least 3 representative dogs of the same breed. You can click on the individual images to zoom in from the case number home page Thoracic radiographic interpretation: The mediastinum (Proceedings) Clifford R. Berry, DVM, DACVR. Mediastinal abnormalities, including cardiac disease, are common causes of clinical signs related to the thorax. By definition, the mediastinum is the midline potential space formed between the two pleural cavities and includes the medial portions. Thoracic radiography is common in small animal practice and is also performed in the horse. Computed tomography (CT) is very useful for characterizing intrathoracic disease in dogs and cats but is not used for thoracic imaging in horses. Magnetic resonance imaging (MRI) is used rarely in veterinary medicine for assessing the thorax Thoracic radiographs in the coughing dog or cat can present a significant interpretive challenge for even the most experienced veterinarians. Evaluating the heart, pulmonary vessels, and pulmonary parenchyma provides a minimum baseline for determining the cause of a patient's respiratory signs
Thoracic radiographs are routinely used in dogs and cats with respiratory disease, but their interpretation remains challenging. The reasons why the pulmonary parenchyma is difficult to evaluate is the fact that many different diseases can have a similar appearance, and there is a large degree of overlap of radiographic manifestation of diseases Other factors affecting the correct interpretation are: 1. Radiological imaging apparatus 2. Respiratory phase 3. Patient habitus In 99.9% of diseases exposure is recommended during inspiration. Expiratory radiography is made in case of air-filled masses (bulla) and collapse of the thoracic section of the trachea and the main bronchi Ventrodorsal thoracic radiograph of a dog with bronchopneumonia involving the right middle lung lobe. A prominent lobar sign is present on both the cranial and caudal edge of the opaque right middle lung lobe. The right border of the heart is silhouetted by the alveolar opacity. An air bronchogram is visible within the opaque lobe 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. It is also not meant to present the range of variation across breeds of the domestic animals
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 Lateral thoracic radiograph from a dog. If you drop an imaginary line (or draw a line) from the carina to the apex of the heart, 2/3rds of the heart should be cranial to the line and 1/3rd should be caudal in a normal patient (dogs). Enlargement of the left atrium is the most common type of cardiomegaly identified radiographically
80 kVp at 5 mAs for a 15-cm dog for a digital plate radiographic system. For any dog measuring 15 cm or greater (measured at the liver or thickest part of the thorax), a grid (8:1, 110 lines per inch) should be used. Grids are available from most radiology manufacturers and a grid tray comes with all radiology units This article will review creating high-quality radiographs of the proximal thoracic limb; specifically the scapula, shoulder joint, and humerus of the dog and cat. High-quality radiography encompasses the application of three areas: positioning, technique, and quality control of the final images Dogs were excluded from the study if they were diagnosed with concurrent nonrespiratory thoracic disease or did not have diagnostic three‐view thoracic radiographs available for review. For each dog, the signalment (age, breed, sex), history, and method of diagnosis were recorded from the medical record by board‐certified veterinary. In many cases, improper positioning or radiographic examination can result in a misdiagnosis or inability to appreciate major lesions. Perhaps the best example of this is in thoracic radiography. Both right and left lateral recumbent radiographs are recommended in dogs and cats
Thoracic radiography is one of the most widely available diagnostic tools when evaluating cardiovascular structures; however, radiographs are only a piece of a larger puzzle Nestlé PURINA Diagnostic Imaging of Dogs and Cats 1 Introduction Wilhelm Conrad Roentgendiscovered x-rays just over 100 years ago, and the first published radiograph was an image of his wife's hand.

Thoracic CT is a powerful non-invasive tool holding potential in diagnosis of pulmonary diseases in which thoracic radiography is unhelpful or unclear. Interpretation of thoracic CT has improved to the point where in humans some diseases can be presumptively diagnosed by historical and clinical findings combined with a specific pattern of. All thoracic radiographs of dogs referred for specialist examination at the Veterinary Teaching Hospital of the University of Padua between January 2014 and October 2019 were reviewed. Signalment was obtained from digital imaging and communications in medicine (DICOM) files and recorded for each patient
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 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 Sixty digital canine thoracic radiographic examinations were interpreted by four groups of three Brazilian observers, each group being defined by different levels of training and experience. The radiographic findings of the 4 groups of observers in the study were compared to a reference interpretation established from the findings of three ACVR. quick reference guide to thoracic radiology.

There is a diffuse micronodular interstitial pattern that is consistent with mycotic pneumonitis. This, coupled with the tibial lesion, makes fungal infection the most likely diagnosis, because this is a very unusual pulmonary pattern to be associated with metastatic osteosarcoma.
Radiographic interpretation 1. AVINASH BVN13007 2. INTRODUCTION:- Radiographic Interpretation is translation of radiographic image into an explanation of the pathology underlying the abnormalities that are observed. But it should be remembered that radiography is not an absolute diagnostic tool but only an adjunct to clinical diagnosis. Similar radiological sign may When it comes to obtaining thoracic radiographs of coughing dogs, diagnostic imaging specialist Dr. Rachel Pollard has tips for improving your image. Sep 08, 2016 By Kathryn Primm, DV Clinical Tip: Thoracic radiographs should be obtained as soon as possible in dogs with respiratory signs. If the findings are ambiguous, the NT-proBNP test may add helpful information regarding likely etiology of signs.
