ABSTRACT
Radiographic images of the thorax are important for evaluating patients with known or suspected thoracic diseases. Thoracic radiography provides direct information about lesions or abnormalities in lung parenchyma, airways, and pleural and mediastinal spaces. Methodology: The present study was carried out between October 2006 and June 2009. Plain thoracic radiography was done on 82 clinical cases of dogs diagnosed clinically as having respiratory disease. Contrast media was used where indicated. The recorded affections were; pectus excavatum [2], tracheal collapse [5], esophegeal dilatation [9], mediastinal foreign body [2], pneumomediastinum [2], tension pneumothorax [5], pneumothorax [12], hydropneumothorax [1], pleural effusion -mild- [4], moderate [9], severe [15], primary lung neoplasm [3], focal metastatic pulmonary neoplasia [7], metastatic tracheobronchial lymphadenopathy [2], metastatic rib neoplasm [1], and pulmonary bullae [3]. Thoracic radiography serves to verify the diagnosis, document the extent and location of the lesion, assist in detecting complication and also helps in classifying the lesions
ABSTRACT
This study was carried out on 50 apparently healthy animals [30 dogs and 20 cats] and 15 dogs suffered from skull affections. Animals were subjected to Conventional plain radiographic imaging [lateral, dorso ventral, rostrocaudal, lateral oblique, open-mouth rostrocaudal, open-mouth lateral, open-mouth ventrodorsal and intra-oral positionings]. Also, positive contrast canalography and rhinography were done to visualize, in details, the acoustic canal and nasal structures respectively. The results revealed that the evaluated Conventional plain radiographic positionings were efficient for imaging the skull anatomy and its affections. Canalography can be regarded as an accurate technique to measure the diameter of the horizontal .ear canal and the tympanic membrane which are predictors of ear diseases. Rhinography was found to be valuable in imaging of nasal sinuses and conchae
