FIGURE 1.3. Ventilation-perfusion imaging in diagnosis of pulmonary embolism. A:Ventilation image, obtained with 99mTc pentetate aerosol, shows homogenous ventilation on posterior view. B: Matched perfusion image shows large (segmental) perfusion defects in the left mid lung, and in the lateral segment of the left lower lobe. There is also decreased perfusion in the right upper lobe. The presence of unmatched segmental abnormalities indicates a high probability for pulmonary embolism.

<bold>Fig C 1-22 Pulmonary infarction.</bold> (A) Chest film made 3 days after open-heart surgery demonstrates a very irregular opacity at the right base (pneumonia versus pulmonary embolization with infarction). (B) On a film made 5 days later, the consolidation is seen to have reduced in size yet to have retained the same general configuration as on the initial view. The diagnosis of pulmonary embolism was confirmed by a radionuclide lung scan.<sup>5</sup>
