  • Title: Ventilation abnormalities associated with pulmonary embolism.
    Author: Sandler MS, Velchik MG, Alavi A.
    Journal: Clin Nucl Med; 1988 Jun; 13(6):450-8. PubMed ID: 3402147.
    Abstract:
    A retrospective analysis of 2035 lung images performed over approximately 5 years revealed abnormal ventilation coexisting with pulmonary embolism in 18 patients. Matching ventilation perfusion defects may be associated with pulmonary embolism without infarction. In patients with a high clinical suspicion of acute pulmonary embolism and matching V/Q abnormalities, an angiogram may be necessary to definitely exclude the diagnosis.
