Three Zone Scanning Protocol For Lung Ultrasound: An Anatomical Basis

Area of Science:

• Medical Imaging
• Pulmonology

Background:

• Lung ultrasound (LUS) is increasingly utilized for its portability, accuracy, and absence of ionizing radiation.
• The COVID-19 pandemic highlighted LUS utility due to concerns over chest X-ray contamination and the need for rapid bedside diagnostics.
• Existing LUS protocols are often complex, lacking a strong anatomical basis.

Purpose of the Study:

• To introduce a simplified, anatomically derived three-zone lung ultrasound scanning protocol.
• To provide an accessible and efficient LUS method for evaluating lung conditions.

Main Methods:

• Development of a three-zone scanning protocol based on surgical understanding of lung and chest wall anatomy.
• The protocol divides the chest into anterior, and posterior zones, correlating with specific lung lobes.
• Application of the protocol for detecting lung consolidations, particularly relevant in bronchopneumonia.

Main Results:

• The three-zone protocol simplifies lung ultrasound examination by correlating surface anatomy with underlying lung lobes.
• Anterior zone corresponds to the upper lobe; posterior zone covers both upper and lower lobes.
• This anatomical approach facilitates easier identification of lung pathology, such as consolidation.

Conclusions:

• A simplified three-zone lung ultrasound protocol, grounded in anatomical principles, offers an effective and user-friendly approach to lung imaging.
• This method enhances the diagnostic utility of lung ultrasound, especially in acute respiratory conditions.
• The protocol's anatomical basis aids in reproducible and accurate lung assessments.
