After viewing this exhibit, the learner will: 1 Recognize the typical appearance of pulmonary ischemia and pulmonary infarction in CT studies of the chest non targeted to pulmonary artery assessment 2 Know when to suspect an occult pulmonary embolism in non-contrast and non-CTPA studies, by recognition of main imaging characteristics of lung ischemia/infarction 3 Differentiate alveolar occupation seen in non-ischemic entities, from that seen in lung parenchymal ischemia/infarction. The "bubbly lung" sign. 4 Understand the importance of early recognition of these imaging findings in the non-angiographic chest CT of patients who present with non-specific respiratory symptoms and misleading clinical signs

1 Anatomy of the lung, emphasizing why it is easily prone to ischemia 2 Radiologic-pathologic correlation of lung parenchymal ischemia 3 Main imaging findings of lung ischemia/infarction in non-contrast chest CT: how to recognize it. 3' The "bubbly lung" sign 4 Case examples
