Coronavirus toll surges after sanction of CT diagnosis
The number of new confirmed cases of coronavirus disease (COVID-19) in China hit roughly 15,000 within the past 24 hours alone, a major increase, according to news reports. The surge follows a decision by Chinese officials to expand the diagnostic criteria for COVID-19 to include cases diagnosed with CT.

CT traces disease progression in novel coronavirus
An ongoing investigation into the novel coronavirus (2019-nCoV) outbreak has characterized the most common CT findings associated with the virus and identified possible markers of disease progression several days after the onset of symptoms. The findings were published online February 6 in Radiology.

CT, x-ray help delineate 1st coronavirus case in U.S.
As the novel coronavirus (2019-nCoV) continues to spread across the globe, CT and radiography have emerged as integral players in its identification and diagnosis. The imaging modalities are also serving pivotal roles in tracking disease progression for the earliest cases, including the first one confirmed in the U.S.
