Summary

Thoracic radiographic and postmortem findings were compared in dogs with histologically confirmed hemangiosarcoma (hsa). On the basis of results of radiography, a false-negative diagnosis was made for pulmonary hsa in 10 (2 1.7%) of 46 dogs, and in 26 (53.1%) of 49 dogs for cardiac hsa. The incidence of false-negative radiographic diagnosis for pulmonary hsa was lower in dogs when left and right lateral views were obtained. The radiographic sensitivity was 78%, and the negative-predictive value was 74% for pulmonary hsa. The radiographic sensitivity was 47%, and the negative-predictive value was 43% for cardiac hsa.

Summary

Results of abdominal ultrasonography in 63 dogs and cats with suspected congenital portosystemic shunts (PSS) were compared with surgical, portographic, and necropsy findings. True-positive ultrasonographic results were found in 33 animals, and 2 animals had falsepositive results for detection of single extrahepatic PSS. In 4 animals, results were true negative and in 8 animals, were false-negative for detection of extrahepatic PSS. The false-negative rate decreased substantially with operator experience. The sensitivity of ultrasonography for detection of extrahepatic PSS in these animals was 80.5%, and the specificity was 66.7%. In 5 other animals, ultrasonographic examination was strongly suggestive of the existence of a shunt, but the vessel could not be definitively imaged. All 5 animals had single extrahepatic shunts. Eleven animals had true-positive results for detection of intrahepatic PSS. One animal had false-positive ultrasonographic results for intrahepatic PSS, but an extrahepatic shunt was diagnosed at surgery. The sensitivity of ultrasonography for detection of intrahepatic PSS was 100%.
