Assessing Lung Parenchymal Enhancement on Dual-Energy CT Pulmonary Angiograms: Potential utility of dual-energy technique as an angiographic and parenchymal 'one-stop shop' in the initial workup of patients with pulmonary symptoms.

This study confirms increased lung parenchymal density when comparing PC and VU reconstructions. Based on results, the paper recommends utilising dual-energy capabilities for VU reconstructions in CTPAs to optimise assessment of lung parenchyma.
