![]() Radiographic features including consolidation, ground glass opacities (GGO), and pulmonary nodules were diagnosed according to the Fleischner Society glossary of terms 18. Further review was undertaken by a third radiologist (MYN, thoracic radiologist with 8 years of experience) if there was disagreement. Two radiologists (HYSL, thoracic radiologist with 15 years of experience HYFW, general radiologist with 5 years of experience) reviewed all CXRs by consensus. All follow-up CXRs were performed in the AP projection using portable X-ray units in the isolation wards. Over half of the CXRs at presentation were performed in the AP projection (36/64, 56%), with the rest in the PA projection. Follow-up CXRs were acquired in the AP projection using portable X-ray units. CXRs were acquired in the posteroanterior (PA) or anteroposterior (AP) projection. To further our understanding of the radiographic features of COVID-19, our study aims to: (i) describe the chest x-ray appearances of COVID-19, (ii) correlate the chest x-ray appearances with reverse transcription polymerase chain reaction (RT-PCR), (iii) compare chest x-ray findings with CT findings, and (iv) describe the time course of chest x-ray appearances relative to symptom onset.Īll CXRs were acquired as computed or digital radiographs following usual local protocols. As the prevalence of COVID-19 increases, it is also imperative for clinicians of all specialties to recognize COVID-19 features on CXR that may be performed for other purposes. Therefore, in some countries, CXR cannot be superseded by CT in the current pandemic. Italian and British hospitals are beginning to employ CXR as a first-line triage tool due to long reverse transcription polymerase chain reaction (RT-PCR) turnaround times 14, 16. ![]() The American College of Radiology notes that CT decontamination required after scanning COVID-19 patients may disrupt radiological service availability, and suggests that portable chest x-ray (CXR) may be considered to minimize the risk of cross-infection 15. Some hospitals in China dedicated specific CT scanners for examining suspected COVID-19 patients only 13, a practice that is being instituted with difficulty in the United Kingdom 14. However, this practice placed a huge burden on radiology departments and posed an immense challenge for infection control in the CT suite. In mainland China, CT was often a first-line investigation for COVID-19 11, 12. The recent COVID-19 radiological literature is primarily focused on CT findings 5– 10, which is more sensitive than chest x-ray (CXR). ![]()
