Magnetic Resonance Assessment of Pulmonary Artery Compliance

p s c l o a Pulmonary hypertension, whether caused by idiopathic pulmonary arterial hypertension or as a complication of an increasingly recognized number of primary disease states, is associated with significant mortality and morbidity (1,2). Diagnosing pulmonary hypertension, however, may be challenging (3). Symptoms can be nonspecific and may be attributed to the underlying disease, and unlike blood pressure monitoring in the systemic arterial tree, there is no simple, inexpensive test for evaluating the pulmonary arteries.
