Magnetic Resonance Imaging of Ventilation and Perfusion Changes in Response to Pulmonary Endarterectomy in Chronic Thromboembolic Pulmonary Hypertension

Abstract

This is a repository copy of Magnetic resonance imaging of ventilation and perfusion changes in response to pulmonary endarterectomy in chronic thromboembolic pulmonary hypertension.

Pulmonary ventilation and micro‐structural findings in congenital diaphragmatic hernia

“…24 Our current study did not assess perfusion, but 3 He ventilation MRI can be used in conjunction with 1 H perfusion MRI to assess ventilation-perfusion distributions with much higher spatial resolution than scintigraphy and with no ionizing radiation dose. 28 This V/Q MRI technique may benefit future studies assessing V/Q distributions in CDH survivors.…”

Statement on imaging and pulmonary hypertension from the Pulmonary Vascular Research Institute (PVRI)

“…Inhaled Xe 129 hyperpolarized gas imaging is an emerging technique. Reports of hyperpolarized gases in CTEPH have suggested a potential role in follow-up of patients 310 and abnormalities in IPAH have also been reported. 311 A patient inhales Xe 129 gas and ventilation images are acquired.…”

Imaging of Pulmonary Hypertension in Adults: A Position Paper from the Fleischner Society

“…Dynamic contrast-enhanced perfusion methods have been used to demonstrate improvement in regional perfusion parameters, regional blood flow, regional blood volume, and mean pulmonary transit time in patients with CTEPH undergoing BPA (113). When coupled with gas ventilation MRI, delayed contrast enhancement perfusion MRI has also been used to assess improvement in lung V/Q matching before and after PEA in CTEPH (114).…”
