In novel coronavirus pneumonia, chest computed tomography (CT) performed better than laboratory tests, according to US media. A study of more than 1000 patients showed that the diagnosis of new crown pneumonia was better than that of the laboratory. The researchers concluded that novel coronavirus pneumonia should be the main screening method for CT.
Novel coronavirus pneumonia is a key factor in the treatment of new crown pneumonia, according to the US ScienceDaily website February 26th.
The guidelines indicated that novel coronavirus pneumonia was diagnosed by reverse transcription polymerase chain reaction (RT-PCR) or respiratory or blood samples, and these results were the key indicators for admission. However, due to the limitations of specimen collection and transportation as well as the performance of the test kit, it is said that in the early stage, the total positive rate of RT-PCR of throat swab is about 30% to 60%.
Novel coronavirus pneumonia is a common disease. In the current public health emergency, RT-PCR's low sensitivity means that a large number of new crown pneumonia patients can not be diagnosed very quickly, and may not receive proper treatment. In addition, given the high infectivity of the virus, there is a risk of an increase in the number of people infected.
"Novel coronavirus pneumonia is very important for early diagnosis and treatment of disease," the authors of the new research paper wrote. Compared with novel coronavirus pneumonia, chest CT imaging may be a more reliable, practical and faster method for diagnosing and evaluating new crown pneumonia, especially in the epidemic area of RT-PCR.
