Non-invasive mapping of organ perfusion and blood flow by CT and MRI highlighted by a case of pulmonary artery stenosis

Abstract

A 65-year-old man with bilateral pulmonary artery stenosis was treated with percutaneous transluminal angioplasty (PTA) and stent implantation in 2002. After being symptom free for 10 years, the patient presented with worsening episodes of acute right ventricular failure and severe dyspnoea. Echocardiography demonstrated a high-grade stenosis of the pulmonary arteries with accelerated flow velocities up to 4.5 m/s. …
