ABSTRACT: Purpose: Dual-energy
CT (DECT) can be used for quantification of lung perfusion blood volume (PBV), allowing
objective evaluation. However, no reports have investigated pulmonary perfusion
correlating with pulmonary artery pressure (PAP) in patients with chronic
pulmonary diseases. The purpose was to evaluate automated quantification of the
lung PBV using dual-energy CT, and its correlation with PAP. Methods: 274
patients who underwent echocardiography within two weeks also underwent CT. The
population was divided into high (≥40 mmHg)and low (
