Pulmonary perfusion imaging using MRI: clinical application

Area of Science:

• Radiology
• Medical Imaging
• Pulmonary Medicine

Background:

• Lung perfusion is vital for oxygenation.
• Pulmonary arterial and parenchymal diseases impair lung perfusion.
• Accurate assessment is critical for patient workup.

Purpose of the Study:

• To provide insight into imaging techniques for lung perfusion assessment.
• To focus on the clinical application of MR perfusion.
• To discuss qualitative and quantitative evaluation methods.

Main Methods:

• Review of current literature on MR perfusion imaging.
• Discussion of non-contrast-enhanced (arterial spin labeling) techniques.
• Exploration of contrast-enhanced perfusion techniques.

Main Results:

• MR perfusion offers valuable insights into lung perfusion.
• Both qualitative and quantitative evaluation methods are discussed.
• Clinical applications in pulmonary and parenchymal diseases are highlighted.

Conclusions:

• MR perfusion imaging is a key tool for evaluating lung perfusion.
• Arterial spin labeling and contrast-enhanced techniques are major methods.
• Understanding these techniques aids in diagnosing and managing lung diseases.
