Cardio-pulmonary MRI for detection of treatment response after a single BPA treatment session in CTEPH patient s

ConclusionCardio-pulmonary MRI detects and quantifies treatment response after a single BPA treatment session.Key Points•Two months after BPA regional parenchymal pulmonary perfusion (PBF) increased in the total lung parenchyma (p = 0.005), the treated lobes (p< 0.0001) and non-treated lobes (p = 0.015).•The PBF treatment changes in the treated lobe were significantly larger than in the non-treated lobes (p = 0.0049).•Change in NT proBNP, MRI-derived mean pulmonary artery pressure, pulmonary transit time, full width at half maximum, right ventricular (RV) ejection fraction, RV stroke volume, cardiac output, ventricular mass index and PBF in the non-treated lobes correlated with PBF change in the treated lobe (p< 0.05).
