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.
