Letter to the Editor: Chest CT and RT-PCR: radiologists’ experience in the diagnosis of COVID-19 in China
In this letter to the Editor, the authors report on their first-hand experience in dealing with COVID-19 in China, highlighting the crucial role of chest CT in early diagnosis and evaluation.
CT image visual quantitative evaluation and clinical classification of coronavirus disease (COVID-19)
The authors of this study analysed COVID-19 patients from Zhuhai, China to compare the relationship between the imaging manifestations and clinical classification of the disease. Based on the sample of 78 patients falling into all 3 categories of the disease (mild, common, and critical), the authors concluded that CT was not suitable as an independent screening tool, but that CT visual quantitative analysis has high consistency and can reflect the clinical classification of COVID-19.
The authors examined initial chest CT data of patients from Chongqing, China, to compare findings from early and progressive stages of COVID-19 disease. In doing so, they were able to identify multiple ground-glass opacities with consolidations in the periphery of the lungs as the primary CT characteristic of the disease, and confirmed that CT score can be used to evaluate the severity of the disease.
The authors of this review combined their experience from the frontlines of the COVID-19 outbreak with a comprehensive literature review to examine the typical and atypical CT manifestations of the disease and provide indications for prompt diagnosis.
This editorial demonstrates that low-dose CT can be equally as effective in COVID-19 detection and diagnosis as the standard CT. The radiation dose is 1/8 or 1/9 of the standard CT protocol, thus allowing for multiple scans with lower cumulative radiation.
Initial CT findings and temporal changes in patients with the novel coronavirus pneumonia (2019-nCoV): a study of 63 patients in Wuhan, China
This study by Yueying Pan, Hanxiong Guan et al., radiologists on the front lines fighting COVID-19, reports that HRCT performed on 63 patients was paramount in the early detection, evaluation of disease severity, and follow-up of infected patients. The study concluded that imaging changes associated with COVID-19 are rapid, and radiologists need to be at the forefront of detection in the battle against it.
This editorial by Hyungjin Kim comprehensively summarises the latest publications on the topic and underlines the role of radiologists not only in detection, but also in defining severity and potential progression of the new disease.
Yueying Pan and Hanxiong Guan shared the first CT images of COVID-19 related pneumonia. It concluded that chest CT examination is very important in the initial diagnosis of the new type of pneumonia, and CT changes are variable.
