DOI: 10.1002/acm2.13071
Abstract: Abstract Purpose Pulmonary perfusion is an important factor for gas exchange. Chest digital dynamic radiography (DDR) by the deep‐breathing protocol can evaluate pulmonary perfusion in healthy subjects. However, respiratory artifacts may affect DDR in patients… read more here.

DOI: 10.1007/s00330-021-08229-6
Abstract: Pulmonary perfusion abnormalities are prevalent in patients with chronic obstructive pulmonary disease (COPD), are potentially reversible, and may be associated with emphysema development. Therefore, we aimed to evaluate the clinical meaningfulness of perfusion defects in… read more here.

Abstract: Introduction: Pulmonary perfusion has been poorly characterized in acute respiratory distress syndrome(ARDS). Optimizing protocols to measure pulmonary blood flow(PBF) via dynamic contrast-enhanced(DCE) computed tomography(CT) could improve understanding of how ARDS alters pulmonary perfusion. In this… read more here.

DOI: 10.1152/japplphysiol.00254.2018
Abstract: Pulmonary vascular tone is known to be sensitive to both local alveolar PO2 and PCO2. Although the effects of hypoxia are well studied, the hypercapnic response is relatively less understood. We assessed changes in regional… read more here.
