 The rumors of CT replacing nucleic acid detection in the circle of friends drew attention to the doctors response


Zhang Xiaochun, deputy director of Medical Imaging Department of Central South Hospital of Wuhan University, became popular overnight because of the statement that CT image is strongly recommended as the first diagnosis method of new crown pneumonia. On the afternoon of February 5, Zhang Xiaochun made his first public statement on his recent remarks.

The views I shared in the circle of friends the other day are based on scientific basis and clinical experience. Zhang Xiaochun said that virus nucleic acid test is the gold standard for the final diagnosis of new coronavirus pneumonia. However, the test results of CT positive, nucleic acid negative may affect the clinical investigation. At present, the new coronavirus nucleic acid detection has high specificity and low sensitivity, and some false negatives are not excluded.

Zhang Xiaochun believes that the detection and diagnosis of the new coronavirus will need some understanding soon after its discovery. In addition, due to the short development time of the nucleic acid kit, the shortage of existing sampling personnel, and the relatively long detection time of the nucleic acid reagent, it is difficult to detect and screen a large number of close contacts, family stay and highly suspected patients in a short period of time.

CT examination is convenient, fast and intuitive, and easy to popularize in primary hospitals. Although CT is only an auxiliary diagnostic method, in todays severe situation of new coronavirus pneumonia, the prevention and control of Wuhan and other regions must take the do not let go of one unconventional means to reduce cross infection. Zhang Xiaochun reminded that patients with positive CT and negative viral nucleic acid test should also be included in the scope of isolation treatment. In an extraordinary period, even pneumonia caused by other pathogens will benefit from timely treatment. Only in this way can we control the source of infection and cut off the route of transmission as soon as possible, so that as many people as possible are not infected, as well as asymptomatic patients infected can be found and treated in time.

Professor Xu Haibo, director of the medical imaging department of Central South Hospital of Wuhan University and vice chairman of the neurology special committee of the Chinese society of Radiology, said that CT is not only a professional means, but also an evidence-based tool; it is both a diagnostician and an evaluator. Therefore, CT as a rapid diagnosis has its own advantages. CT screening may be the first choice for the diagnosis of new crown pneumonia in Hubei Province. It is understood that Professor Zhao Shihua of Beijing Fuwai Hospital, Professor Wu Jianlin of Zhongshan Hospital of Dalian Medical University, Professor Ou Shanxing, chief physician of Radiology Department of Southern theater General Hospital of the Chinese peoples Liberation Army and many other experts in the industry recently joined Professor Zhang Xiaochun through telephone, wechat or self-Media platform to express their approval and support for her views. After Zhang Chunhongs comments were widely spread. The National Health Commission has also taken action. On February 4, the general office of the national health and Health Commission and the State Administration of traditional Chinese medicine jointly issued the new coronavirus infection pneumonia diagnosis and treatment plan (trial version 5), which took suspected cases with pneumonia imaging characteristics as the clinical diagnosis case standard of Hubei Province.
