Detection of pulmonary emboli was investigated using electrocardiographically gated (EKG-gated) intravenous digital subtraction angiography (DSA) in 6 anesthetized and paralyzed dogs. Six autologous blood clots were introducted into the internal jugular vein of each dog and both conventional pulmonary angiography and EKG- gated DSA performed in frontal and oblique projections. The authors conclude that DSA can demonstrate individual emboli with good sensitivity and excellent precision. If several emboli are present, KEG-gated DSA should prove highly accurate; however, care must be taken because overinterpretation is more likely with DSA than with conventional pulmonary angiography.
