[Functional 3He-MRI of the lungs]

Area of Science:

• Pulmonary Medicine
• Medical Imaging
• Respiratory Physiology

Context:

• Pulmonary diseases pose significant health and economic burdens.
• Traditional imaging methods have limitations in assessing ventilation.
• Helium-3 MRI (³He-MRI) emerges as a sensitive alternative.

Purpose:

• To evaluate ³He-MRI for assessing ventilatory disturbances in pulmonary diseases.
• To explore the capabilities of ³He-MRI in static and dynamic lung function assessment.
• To investigate the potential of ³He-MRI in quantifying lung destruction and gas exchange.

Summary:

• ³He-MRI detects ventilatory disturbances with high sensitivity.
• Utilizes diverse pulse sequences for static/dynamic ventilation and gas flow analysis.
• Enables non-invasive oxygen partial pressure measurement and lung parenchyma quantification.
• Applicable to obstructive, restrictive, and potentially vascular pulmonary diseases.

Impact:

• Provides a non-invasive tool for detailed pulmonary ventilation assessment.
• Enhances understanding of physiological and pathophysiological processes in lung diseases.
• Offers potential for improved diagnosis and management of diverse respiratory conditions.
