A Pilot Trial on Pulmonary Emphysema Quantification and Perfusion Mapping in a Single-Step Using Contrast-Enhanced Dual-Energy Computed Tomography

Abstract

We observed moderate correlations between quantitative parameters on VNC images and pulmonary function test data, and also observed moderate correlations between the severity of parenchymal destruction, as determined from VNC images, and perfusion status, as determined from iodine maps. Therefore, the contrast-enhanced DECTA can be used for the emphysema quantification and regional perfusion evaluation by using the VNC images and iodine map, simultaneously.
