Comparison of computed tomography and thoracic radiography findings for the assessment of pulmonary diseases in dogs
Abstract
Radiographic examination is a common method for diagnosis of pulmonary diseases but it is not always adequate for accurate diagnosis. Therefore, an advanced imaging method as computed tomography (CT) was used in this study for veterinary purposes. This study aimed the comparison of the two imaging methods for evaluation of pulmonary diseases in dogs. 20 dogs of various breeds, age and sex with complaints of lung disease made up the materials of the study. Following the patient history and clinical examination, radiographic examination and CT examination were performed and the outcomes were evaluated. Pulmonary nodules/masses or calcified foci in 12 patients, pleural effusion and pneumothorax in 4 patients, pulmonary edema in 2 patients, tracheal collapse and megaesophagus in two patients were diagnosed by using both radiographic and CT examination. As a conclusion, radiographic examination provides an initial diagnosis for severe diseases and can be used as first imaging modality for lung diseases, but CT has superiority over radiography due to its ability to provide cross-sectional images and more accurate diagnosis

Köpeklerde akciğer hastalıklarının tanısında bilgisayarlı tomografi ve torasik radyografi bulgularınınkarşılaştırılması
Abstract
Akciğer hastalıklarının tanısında radyografik muayene sıklıkla kullanılan bir yöntemdir; ancak kesin tanı için yetersiz kalmaktadır. Bu çalışmada ileri görüntüleme yöntemi olan bilgisayarlı tomografi, veteriner amaçlı kullanılmıştır. Çalışmada, bahsi geçen iki görüntüleme yönteminin akciğer hastalıklarında birbirlerine olan üstünlüğü karşılaştırılmıştır. Solunum şikayeti ile kliniğe başvuran çeşitli ırk, yaş ve cinsiyetteki 20 köpek çalışmaya dahil edilmiştir. Hastalara ait anamnez bilgileri alınıp klinik muayeneleri yapıldıktan sonra, radyografik muayene ve bunu takiben bilgisayarlı tomografi ile inceleme yapılmıştır. On iki hastaya pulmoner nodül, kitle ya da kalsifiye odak, dört hastaya plöral efüzyon ve pnömotoraks, iki hastaya pulmoner ödem ve iki hastaya trakeal kollaps ve megaözofagus tanısı hem radyografik hem de BT muayenesi sonucunda konulmuştur. Sonuç olarak, radyografi akciğer hastalıklarında öncül tanı konulması amacıyla ilk görüntüleme yöntemi olarak kullanılabilir. Bilgisayarlı tomografide kesit görüntü elde edilebilmesi sonucunda, kesin tanıya giden yolda radyografiye olan üstünlüğü ortaya konmuştur
