Patterns of COVID-19 on computed tomography imaging

Abstract

As the designated tertiary referral centre for infectious diseases in Hong Kong, our hospital received the city's first group of patients diagnosed with coronavirus disease 2019 . Herein, we studied the earliest patients admitted to our centre in order to clarify the typical radiological findings, particularly computed tomography (CT) findings, associated with COVID-19.Methods: From 22 January 2020 to 29 February 2020, 19 patients with confirmed COVID-19 underwent high-resolution or conventional CT scans of the thorax in our centre. The CT imaging findings of these patients with confirmed COVID-19 in Hong Kong were reviewed in this study.Results: Ground-glass opacities (GGO) with peripheral subpleural distribution were found in all patients (100%). No specific zonal predominance was observed. All lobes were involved in 16 (84.2%) patients, focal subsegmental consolidations were observed in 14 (73.7%) patients, and interlobular septal thickening was present in 12 (63.2%) patients. No mediastinal lymph node enlargement, centrilobular nodule, or pleural effusion was detected in any of the patients. Other imaging

The percentage of hemoglobin Bart’s among group of neonates in Al-Najaf City

“…Our study show no difference in expression of Hb Bart's percentage, in either female and male, which goes well with the recessive inheritance of the disease, these findings agreed with Chi Kong Li et al study [24] which had been reported no difference in the prevalence of thalassemia between both sexes.…”

Emergency Protective Measures and Strategies of COVID-19: From Lifestyle to Traditional Chinese Medicine

“…Genome sequences from samples of patients confirmed that COVID-19 was originated from a novel coronavirus, the SARS-CoV-2 ( Zhou et al, 2020 ; Wu et al, 2020 ; Lam et al, 2020 ), and its variants (Delta and Omicron). One the other hand, COVID-19 crisis inspires the global scientists and labs scrambling to develop new coronavirus diagnostics, medical experimental studies (e.g., Remdesivir and Chloroquine) ( Wang et al, 2020 ), and clinical trials (e.g., Lianhua Qingwen ( Li et al, 2020 ), Paxlovid, and VV116 from basic research ( Xie et al, 2021 ; Zhang et al, 2022 ; Lou et al, 2023 ) to clinical studies ( Cao et al, 2022 ; Qian et al, 2022 ; Shen et al, 2022 ) for specific antiviral treatments ( Table 1 ), and rapid developing novel vaccines of COVID-19 due to new understanding on the structure of SARS-CoV-2 ( Wrapp et al, 2020 ; Walls et al, 2020 ; Yan et al, 2020 ). Herein, it's time for collaboration between social and natural science for better combating the pandemics.…”

“…It's believed that we will be powerful in combating the SARS-CoV-2 infection and COVID-19 with these emergency protective measures combined with the iRT-ABCDEF program developed in recent years, with the further understanding the epidemiology, risk factors, distribution ( Chen et al, 2020 ), clinical and radiological characteristics ( Wang et al, 2020 ; Hu, 2020 ; Chen et al, 2020 ; Guan et al, 2020 ; Wang et al, 2021 ; Li et al, 2020 ) as well as complications ( Deng et al, 2020 ) of COVID-19 in China, the development of rapid diagnostic methods and reagents, effective antiviral drugs and cardiac protection, clinical trials on vaccines, a good international cooperation and information sharing ( Moorthy et al, 2020 ). Since re-infection is possible after recovery from COVID-19 ( Law et al, 2020 ), positive public health interventions by medical workers, the community and local health authorities are vital to control and prevent the COVID-19 pandemic ( Yu et al, 2020 ).…”

Scientific research on COVID-19 conducted in Hong Kong in 2020

“…A local study conducted by radiologists assessed the use of computed tomography (CT) scanning of the thorax as a non-invasive imaging modality in exploring viral pneumonia patterns that were commonly encountered in affected patients. 15 This provides an opportunity to gain temporal insights into the extent of lung involvement on CT images and determine the accuracy of CT severity scoring in clinical triage and the prediction of post-COVID outcomes. It is highly sensitive, accessible, portable, and easy to operate, 16 playing an important role in identification of COVID-19.…”
