To analyze the image characteristics of cardiogenic pulmonary edema and the pathophysiological mechanisms that form the image characteristics so as to provide more reliable evidences for clinical diagnosis.

Fifty-three patients with cardiogenic pulmonary edema previously admitted to our hospital were collected as the research subjects, and the relevant data were analyzed by retrospective analysis to explore its imaging characteristics and pathophysiological relationship.

The patients with cardiogenic pulmonary edema were mainly manifested by interstitial pulmonary edema and alveolar pulmonary edema, and were often accompanied by imaging findings such as enlarged heart. In the left heart failure, due to the decline in the pumping function of the heart, the pulmonary vein pressure increased, the secondary pulmonary vein capillary pressure increased, and the fluid penetrated into the interstitial lung and then interstitial pulmonary edema occurred. If the pathological process was not corrected in time, the fluid would further leaked into the alveolar cavity and then alveolar pulmonary edema occurred. The imaging manifestations of cardiogenic pulmonary edema were closely related to the pathophysiology during the development of the disease.

Different types and different degrees of pulmonary edemas have both imaging similarities and differences, but the imaging performance of pulmonary edema is always closely related to the pathophysiology. The differences in the pathophysiological mechanisms of different pulmonary edemas are helpful to correctly and quickly identify the disease and assist in determining the condition, and have practical clinical significance.
