Magnetic resonance angiography (MRA) of the pulmonary arteries still is a rapidly evolving technique with already proved high clinical usefulness. Contrast-enhanced and non-contrast-enhanced angiographic techniques are widely available for high spatial or real-time imaging of the pulmonary arteries. Multiple step protocols, such as perfusion MR imaging followed by high spatial resolution contrast-enhanced MRA, seem to be an optimal clinical approach for the assessment of different vascular diseases affecting the pulmonary arteries. This review article describes the MR imaging techniques available and their application in acute and chronic thromboembolic disease.

UI	MeSH Term	Description	Entries
D006976	Hypertension, Pulmonary	Increased VASCULAR RESISTANCE in the PULMONARY CIRCULATION, usually secondary to HEART DISEASES or LUNG DISEASES.	Pulmonary Hypertension
D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.
