Lung Perfused Blood Volume Images With Dual-Energy Computed Tomography for Chronic Thromboembolic Pulmonary Hypertension

Abstract

Lung perfused blood volume imaging by dual-energy CT is feasible for the evaluation of pulmonary perfusion and is comparable to pulmonary scintigraphy. It is possible to evaluate vessels and pulmonary perfusion with CT pulmonary angiography and LPBV images and to assess pulmonary perfusion more definitively in diagnosing chronic pulmonary thromboembolic embolism.
