Abstract
In this research article, we describe CT findings in lungs in a group of 100 cats with inflammatory diseases of lower respiratory system. We present analysis of tomograms and findings with contrast medium and without it. The aim of research. To create the sample of images with the morphologically confirmed diagnoses. Materials and methods. In the study the cats 100 were included. Males 54 %, females 46 %. Median age 7.2±0.43. The cats older than 10 years comprised 30 %, cats younger than 1 year ― 11 %. Distribution on the breeds: non-breed cats ― 63 %, Maine-coon ― 8 %, British cats ― 8 %, Kurilian bobtail ― 4 %, Abyssinian cats ― 3 %, Don Sphynx ― 3 %, Neva Masquerades ― 2 %, Oriental cats ― 2 %, Persian cats ― 2 %, Birma, Siamese, Singapura, Siberian and Cornish Rex ― on 1 %. We use two types of CT scanners: one-slice CT Picker PQ 6000 and sixteen-slice CT Siemens Somatom Emotion 16. Morphological confirmation of the diagnosis was made using bronchoalveolar lavage, cytological and histological studies. Other methods included physical examination, clinical blood tests and serological tests. Results. CT has surpassed radiography, 20 % sensitivity, 79 % specificity. Mixed type of lung pattern was observed in 73 % cases. The predominant type of pulmonary pattern was interstitial pattern 82 %. Bullas were detected in 11 % of cats, total fibrosis was confirmed in 6 % of cats. Pulmonary embolism was confirmed in 2 cats. Conclusions. CT is a valuable diagnostic technique of thorax examination in cats. The use of CT is always rational when radiography in three projections did not provide convincing information on the state of the thorax.
