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.


CONCLUSIONS
The two major techniques, non-contrast-enhanced (arterial spin labeling) and contrast-enhanced perfusion techniques, are discussed.
