Pulmonary perfusion imaging using MRI: clinical application

Background Lung perfusion is one of the key components of oxygenation. It is hampered in pulmonary arterial diseases and secondary due to parenchymal diseases. Methods Assessment is frequently required during the workup of a patient for either of these disease categories. Results This review provides insight into imaging techniques, qualitative and quantitative evaluation, and focuses on clinical application of MR perfusion. Conclusion The two major techniques, non-contrast-enhanced (arterial spin labeling) and contrast-enhanced perfusion techniques, are discussed.
