Thirty cases of acute pulmonary edema were analyzed in this study, including 15 cases of cardiogenic pulmonary edema, 8 cases of renal-derived pulmonary edema and 7 cases of capillary-induced pulmonary edema. The distribution of pulmonary blood flow, the distribution of pulmonary edema and the width of vascular root Three main signs; pulmonary blood volume, hilar structure, interval lines, bronchial cuff signs around, bronchial meteorology, veil signs, pleural effusion and heart size and other eight auxiliary signs of differential diagnosis of cardiogenic and non-cardiac pulmonary edema It is pointed out that the careful observation and analysis of some x-ray features and the close combination of clinical data can accurately identify the cause of pulmonary edema in most cases.
