upper lobe pulmonary venous diversion ( stag's antler sign).The chest radiograph remains the most practical and useful method of radiologically assessing and quantifying pulmonary edema 3,4.įeatures useful for broadly assessing pulmonary edema on a plain chest radiograph include: The causes of non-cardiogenic pulmonary edema can be recalled with the following mnemonic: NOTCARDIAC. pulmonary edema from anti-snake venom administration 8.post lung volume reduction pulmonary edema.pulmonary edema following lung transplantation.pulmonary edema following administration of cytokines.ARDS: pulmonary edema with diffuse alveolar damage.near-drowning pulmonary edema / asphyxiation pulmonary edema.pulmonary edema in pulmonary thromboembolism.postobstructive pulmonary edema / postintubation pulmonary edema/ negative pressure pulmonary edema.mixed edema due to simultaneous increased hydrostatic pressure and permeability changesīroadly causes can be classified as cardiogenic and non-cardiogenic:.permeability edema without diffuse alveolar damage (DAD).permeability edema with diffuse alveolar damage (DAD).these phases are virtually identical for left heart failure and fluid overload.two pathophysiological and radiological phases are recognized in the development of pressure edema.
One method of classifying pulmonary edema is as four main categories on the basis of pathophysiology which include: He graduated from University of Pennsylvania School of Medicine and completed his residency in radiology at the Hospital of the Univ of Penn of UPHS.The clinical presentation of pulmonary edema includes: has been the recipient of numerous teaching awards at the University of Pennsylvania School of Medicine, and is dedicated to clinical, academic, and teaching excellence.

Normal lung xray series#
By reading this series of Normal CXR, students will learn to appreciate the range of "normal" markings, the basics of CXR reading, and how patient age and sex influence differentials. We have assembled 100 "normal" Chest X-Rays that were given the Diagnosis of "No Active Disease" (NAD) at the Hospital of the University of Pennsylvania (HUP). One of the most difficult things to learn when first reading Chest X-Ray (CXR) films is what is "normal" and what is really "active disease." This website aims to help students become comfortable with accepting artifacts of blood vessels as "normal," with the hopes that students will then more easily identify "abnormal" signs of active disease. Welcome! This website was created to help introduce medical students to chest radiology.
