Supine hyperpolarized 3 helium gas scan

Eric A. Hoffman · FDA-approved active Small molecule

Hyperpolarized helium-3 gas imaging is a diagnostic imaging technique that uses polarized helium-3 atoms to visualize ventilation patterns and lung function in real-time.

Hyperpolarized helium-3 gas imaging is a diagnostic imaging technique that uses polarized helium-3 atoms to visualize ventilation patterns and lung function in real-time. Used for Functional lung imaging for assessment of ventilation defects, Evaluation of chronic obstructive pulmonary disease (COPD), Assessment of asthma and other obstructive airway diseases.

Mechanism of action

The helium-3 nuclei are hyperpolarized to enhance their magnetic resonance signal, allowing detailed visualization of gas distribution throughout the lungs during breathing. This non-invasive imaging modality can detect regional ventilation defects and abnormalities in lung function that may not be visible on conventional imaging, providing functional assessment of pulmonary disease.
