  • Title: Quantification of lung perfusion blood volume (lung PBV) by dual-energy CT in pulmonary embolism before and after treatment: preliminary results.
    Author: Nagayama H, Sueyoshi E, Hayashida T, Ashizawa K, Sakamoto I, Uetani M.
    Journal: Clin Imaging; 2013; 37(3):493-7. PubMed ID: 23041162.
    Abstract:
    The purpose was to investigate the quantification of lung perfusion blood volume (PBV) by dual-energy computed tomography (CT) in patients with pulmonary embolism (PE) before and after treatment. Twenty-five patients with PE underwent dual-energy CT angiography before and after treatment. In all 25 patients, pulmonary CT confirmed that there was no PE after treatment. This preliminary study demonstrated the possibility that quantification of lung PBV may reflect parenchymal arterial perfusion before and after treatment, including the compensatory increase of lung perfusion.
