T27 0-149 Sentence denotes The clinical symptoms associated with COVID-19 include fever, dry cough, dyspnea, and pneumonia, as described in the guideline released by the WHO13.
T28 150-312 Sentence denotes It has been recommended to use the WHO’s case definition for influenza-like illness (ILI) and severe acute respiratory infection (SARI) for monitoring COVID-1913.
T29 313-468 Sentence denotes As reported by the CHINA-WHO COVID-19 joint investigation group (February 28, 2020)14, autopsies showed the presence of lung infection in COVID-19 victims.
T30 469-647 Sentence denotes Therefore, medical imaging of the lungs might be a suitable auxiliary diagnostic testing method for COVID-19 since it uses available medical technology and clinical examinations.
T31 648-818 Sentence denotes Chest radiography (CXR) and chest computed tomography (CT) are the most common medical imaging examinations for the lungs and are available in most hospitals worldwide15.
T32 819-995 Sentence denotes Different tissues of the body absorb X-rays to different degrees16, resulting in grayscale images that allow for the detection of anomalies based on the contrast in the images.
T33 996-1116 Sentence denotes CT differs from normal CXR in that it has superior tissue contrast with different shades of gray (about 32–64 levels)17.
T34 1117-1205 Sentence denotes The CT images are digitally processed18 to create a three-dimensional image of the body.
T35 1206-1274 Sentence denotes However, CT examinations are more expensive than CXR examinations19.
T36 1275-1412 Sentence denotes Recent studies reported that the use of CXR and CT images resulted in improved diagnostic sensitivity for the detection of COVID-1920,21.
T37 1413-1507 Sentence denotes The interpretation of medical images is time-consuming, labor-intensive, and often subjective.
T38 1508-1607 Sentence denotes The medical images are first annotated by experts to generate a report of the radiography findings.
