In-vivo quantitative assessment of pulmonary edema and fibrosis using ultrasound multiple scattering

摘要

The lung parenchyma is a highly complex and diffusive medium for which ultrasound (US) techniques have remained qualitative. US quantitative characterization of the lung has remained elusive due to the presence of air-filled alveoli which is responsible for Multiple Scattering (MS). There is a need from pulmonologists for a method which would enable them to stage and monitor pulmonary edema and fibrosis using US.
