Area of Science:

  • Pulmonary Medicine
  • Medical Imaging
  • Radiology

Background:

  • Current lung imaging primarily focuses on morphology, with functional data lacking regional information.
  • Computed tomography is standard for pulmonary diseases, but functional assessment relies on methods like spirometry, which lack spatial detail.
  • Arterial blood gas analysis, spirometry, and body plethysmography provide limited regional functional insights into lung diseases.

Purpose of the Study:

  • To review the experience with hyperpolarized helium-3 Magnetic Resonance Imaging (3He-MRI) for functional lung assessment.
  • To highlight the capabilities of 3He-MRI in providing regional pulmonary function data.
  • To present the international background and experience at the University of Mainz, a leading center for 3He-MRI in humans.

Main Methods:

  • Utilizing hyperpolarized helium-3 (3He) as a contrast agent for Magnetic Resonance Imaging (MRI) of the lung.
  • Implementing four distinct image acquisition modes during patient studies.
  • Advancing lung MRI through novel contrast mechanisms for functional imaging.

Main Results:

  • 3He-MRI delivers functional lung information with high spatial and temporal resolution.
  • This technique offers a method for assessing lung function without the risks associated with ionizing radiation.
  • Current limitations include the high cost and limited availability of hyperpolarized 3He gas.

Conclusions:

  • 3He-MRI represents a significant advancement in functional lung imaging.
  • The technique provides valuable regional functional data, complementing morphological imaging.
  • Despite cost and availability challenges, 3He-MRI shows promise for the assessment of pulmonary diseases.
