Miao C, Jin M, Miao L, et al. - Researchers sought to differentiate the imaging features of COVID-19 from those of other infectious pulmonary diseases. Further, they investigated the diagnostic value of chest CT for suspected COVID-19 patients. Enrollment was performed of 130 suspected cases of COVID-19 (age > 18 years) who underwent chest CT scans and reverse-transcription polymerase chain reaction (RT-PCR) tests within 14 days of symptom onset. Of these cases, 54 tested positive and 76 tested negative. The positive group exhibited the following typical CT imaging features: ground glass opacities (GGOs), the crazy-paving pattern and air bronchogram; the lesions were mostly distributed bilaterally and close to the lower lungs or the pleura. Observation suggest the possible utility of the combinations with GGOs in the identification and differential diagnosis of COVID-19, alerting clinicians to isolate cases for prompt treatment and repeat RT-PCR tests until the end of incubation.
