This study is looking at how a special type of MRI, called 129Xe MRI, can help doctors understand and track pulmonary arterial hypertension (PAH). PAH is a condition where blood pressure in the arteries of your lungs is too high. Researchers want to see if 129Xe MRI can show differences between common types of PAH and how well treatments are working over time. You might be able to join if you are 18-75 years old and have Idiopathic PAH or PAH linked to a connective tissue disease. The study will measure changes in your lung blood vessels using the 129Xe MRI over one year to see if it's a good way to monitor the disease.

Study design

This is an observational study involving 20 participants, split into two groups of 10 each, to compare different types of PAH.

What's involved

You would undergo 129Xe MRI/MRS scans at baseline, 3 months, 6 months, and 12 months. Standard medical assessments like labs, echocardiograms, and 6-minute walk tests will also be collected at these times.

Compensation

Not stated in the trial record.

Follow-up

Participants will be followed for 12 months to track changes in their condition.
