Overview of MRI for pulmonary functional imaging

Area of Science:

• Pulmonary Medicine
• Medical Imaging
• Biophysics

Background:

• Morphological lung evaluation is crucial for diagnosing pulmonary diseases.
• Early-stage lung diseases may alter pulmonary function before structural changes are apparent.
• Traditional imaging may not fully capture early functional pulmonary pathophysiology.

Purpose of the Study:

• To review state-of-the-art Magnetic Resonance (MR) imaging methods for pulmonary functional assessment.
• To discuss future directions in MR-based ventilation, perfusion, and biomechanical imaging of the lungs.

Main Methods:

• Overview of current advanced MR imaging techniques.
• Discussion of technical approaches in nuclear medicine, CT, and MR imaging.
• Focus on MR methods for ventilation, perfusion, and biomechanical evaluation.

Main Results:

• Advanced MR imaging offers novel insights into pulmonary function beyond structural morphology.
• MR techniques are being developed for detailed assessment of lung ventilation and perfusion.
• Biomechanical evaluation using MR provides a new dimension for understanding lung function.

Conclusions:

• MR imaging is a promising tool for non-invasive pulmonary functional assessment.
• Future MR developments will enhance the understanding and diagnosis of lung diseases.
• Integrating ventilation, perfusion, and biomechanical MR imaging can provide comprehensive pulmonary functional data.
