Correlation between thoracic radiographs and postmortem findings in dogs with hemangiosarcoma: 77 cases (1984-1989).

Abstract

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 (21.7%) 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.
