DIAGNOSIS OF HEPATIC TUMORS IN DOG BY USING COMpUTED TOMOGRAPHY SCANING
The article provides an investigation of using computer-assisted tomography (CAT) for differential diagnosis of liver tumors in dogs. Using Toshiba Asteon Super 4 equipment multiple cutting technology of Asteon 4 system allowed true isotropic 3-D data imaging which enabled to view the research results in any projection without losing image quality. Basing on standard investigation with native phase, 80% of the dogs were scanned with intravenous contrast. The CAT-results identified the differences between the form of primary tumor focus, hepatocellular cancer and cholangiocellular cancer, as well as the contours of tumors and liver morphology. The CAT accuracy in metastases detection was 86%. Using the computer-assisted tomography method to investigate liver tissues allows evaluation of liver size and contours, direct and detailed imaging of both the inner structure and various neoplasms in an organ for more accurate detection and discriminatory diagnosis.
