Introduction Respiratory disease in cattle is the most prevalent cause of morbidity and mortality in beef feedlots, and the most common cause of morbidity in weaned dairy calves (). Early diagnosis of disease is essential to reduce the risk of disease propagation and to decrease the financial costs from treatment and loss of animals. Furthermore, early diagnosis promotes good quality of life for the patient, improves response to treatment, and decreases the likelihood of prolonged morbidity following juvenile pneumonias (, ). Calves with respiratory disease often present with fever, cough, and tachypnea. Auscultation is commonly used to further evaluate the lungs.

In July 1989 The Veterinary Record reported that it had published only eight articles on lameness in dairy cattle during the previous five years, compared with 278 articles on. Radiography may be used to confirm the diagnosis. Comparison of Thoracic Radiography and Computed Tomography in Calves with Naturally Occurring Respiratory Disease. Image Jennifer Fowler1, image. Calves were housed with free choice of water, calf starter, and were fed milk replacer twice daily until the imaging studies were performed. All imaging studies were.

However, several of these clinical findings have been proven unreliable to diagnose pneumonia in calves. As such, diagnosis of bovine respiratory disease remains a diagnostic challenge. Thoracic radiography is the most commonly used test of choice to evaluate for pneumonia in human and veterinary patients. Radiography of the thorax of large animals can be limited to having only lateral projections of the thorax available for interpretation and by inadequate penetration due to the size of large animals and equipment limitations; however, its practicality including its use in field conditions, low cost, and widespread availability make it one of the most common used techniques to evaluate the thorax in large animals with respiratory disease (–). Computed tomography (CT) of the thorax is considered the modality of choice to evaluate for the presence of lung disease in human patients and is increasingly used in veterinary patients (). Thoracic CT has proven to be helpful for evaluating the extent of pulmonary disease and provides better anatomic detail due to a lack of superimposition of anatomical structures ().

The use of CT in calves is often limited by the cost and lack of availability of a CT scanner close to a calf rearing operation. Furthermore, CT examinations of the thorax are commonly performed under general anesthesia with endotracheal intubation to allow using breath-hold techniques, which decrease the risk of respiratory motion (, ). However, calves with severe respiratory impairment due to pneumonia often have an increased anesthetic risk. Although CT scanning protocols have been described for awake and sedated patients including for normal cats and cats with upper airway obstruction and intrathoracic disease, dogs with acute abdominal signs, and dogs with traumatic pelvic fractures, as well as healthy sedated foals neither has been evaluated in calves to date (–).
