Lung and kidney perfusion deficits diagnosed by dual-energy computed tomography in patients with COVID-19-related systemic microangiopathy	2020-08-29		.txt	text/plain	4508	249	48	title: Lung and kidney perfusion deficits diagnosed by dual-energy computed tomography in patients with COVID-19-related systemic microangiopathy We evaluated lung and kidney perfusion abnormalities in patients with COVID-19 by dual-energy computed tomography (DECT) and investigated the role of perfusion abnormalities on disease severity as a sign of microvascular obstruction. CONCLUSIONS: We found that a large proportion of patients with mild-to-moderate COVID-19 had PDs in their lungs and kidneys, which may be suggestive of the presence of systemic microangiopathy with micro-thrombosis. KEY POINTS: • Pulmonary perfusion abnormalities in COVID-19 patients, associated with disease severity, can be detected by pulmonary DECT. Here, we aimed to evaluate lung and kidney perfusion abnormalities in COVID-19 patients by dual-energy computed tomography (DECT) and to investigate the role of perfusion abnormalities on disease severity as a sign of microvascular obstruction. Perfused blood volume (PBV) images and iodine maps were generated using DECT post-processing software ("Lung PBV" and "Virtual unenhanced" in syngo Dual Energy; Siemens Healthineers) on a dedicated workstation.	./cache/cord-276834-20lcihf4.txt	./txt/cord-276834-20lcihf4.txt
