Summary

Historically, ultrasound imaging of the lung parenchyma has been challenging because of the high total ultrasound energy attenuation and scattering by the air in the lungs. However, recent technological advancements have allowed for rapid assessment of various pulmonary diseases via the use of lung ultrasound. Furthermore, it has been shown that clear reproducible Doppler signals can be recorded from the lung parenchyma by means of a pulsed Doppler ultrasound system incorporating a special signal-processing package.

The LDS may contain information of significant diagnostic and physiological value regarding the pulmonary parenchyma and vasculature, as well as the cardio-vascular system in general. In a pilot clinical validation study of patients with acute decompensated heart failure (ADHF) patients, LDS signals unique to ADHF patients were identified, that superpose on the normal Lung Doppler Signals (unpublished data). These are high velocity "disorganized" variable signals that are not synchronous with the cardiac cycle but rather sometimes with respiration.
