Abstract: To characterize CT-ndings of COVID-19 pneumonia and their value in diagnosis and outcome prediction. METHODS Chest CTs of 182 patients with a con rmed diagnosis of COVID-19 infection by RT-PCR were evaluated for the presence of CT-abnormalities and their frequency. Regarding the patient outcome each patient was categorized in 5 progressive stages and the duration of hospitalization was determined. Regression analysis was performed to nd which CT ndings are predictive for patient outcome and to assess prognosti… Show more

“…2). [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37] The heterogeneity among studies was significant (I 2 : 89.2%, p < 0.001) and was not reduced by the exclusion of one study at time. Results were similar when specifically analyzing studies on ICU patients (WMP: 32.7%, 95% CI: 21.9-45.7%; I 2 : 89.9%, p < 0.001).…”

“…In an autopsy series of 12 patients, Wichmann et al reported a high incidence of deep venous thrombosis and pulmonary embolism [5]. In 337 COVID-19 patients who underwent CTPA, Poyiadji et al reported pulmonary embolism in 22% of cases [17]. Another explanation for ACP is distal microthrombosis of the pulmonary circulation due to extensive in ammation in the lung.…”

“…(4) Among 15 in 17 studies reported venous thrombotic outcomes, utilized anticoagulant prophylaxis. In the imaging studies, 6 studies mainly focused on CTPA in all hospitalization patients (25)(26)(27)(28)(29)(30), and 2 studies focused on using compression ultrasound (CUS) in a non-ICU setting. (31, 32) Subgroup analyses of VTE based on anticoagulant prophylaxis, eastern or western countries, and CUS screening did not reveal signi cant differences between subgroups ( Figures S3-S5 in the supplementary index).…”
