Hydrostatic pulmonary edema: evaluation with thin-section CT in dogs.

摘要: PURPOSE: To identify the hemodynamic determinants of ground-glass opacification on thin-section computed tomographic (CT) scans hydrostatic pulmonary edema and to compare attenuation subjective assessments with extravascular lung water. MATERIALS AND METHODS: Left atrial pressure, arterial effective capillary water were measured in six dogs before during progressive increase pressure. A CT scan was obtained at each step. Lung compared variables RESULTS: Ground-glass identified when pressure equaled critical Extravascular increased, distribution curve coefficients shifted higher from second measurement a...
