摘　　要：To the Editor:The coronavirus disease 2019(COVID-19)pandemic has caused a significant global health crisis,led to staggering mortality rates,and imposed a substantial economic burden.[1]Pneumonia is the leading cause of mortality in patients with COVID-19.During outbreak peaks,the surge in patients severely strained healthcare systems,highlighting the need for rapid and cost-effective screening methods.Although chest X-ray(CXR)is affordable and convenient,its low sensitivity limits its effectiveness for detecting lung abnormalities.Computed tomography(CT)is considered the gold standard for diagnosing pneumonia,including COVID-19 pneumonia,but it exposes patients to high doses of radiation(3-7 mSv)far exceeding the annual threshold of 1 mSv recommended by the World Health Organization.Even low-dose CT delivers an average effective dose of 1.6 mSv,adding to the patient’s radiation burden.
