Egy idő után a kínaiak is átálltak a CT-re, mert gyorsabb és úgy találták, hogy pontosabb is: https://www.sciencedaily.com/releases/2020/02/200226151951.htm
The results showed that 601 patients (59%) had positive RT-PCR results, and 888 (88%) had positive chest CT scans. The sensitivity of chest CT in suggesting COVID-19 was 97%, based on positive RT-PCR results. In patients with negative RT-PCR results, 75% (308 of 413 patients) had positive chest CT findings. Of these, 48% were considered as highly likely cases, with 33% as probable cases. By analysis of serial RT-PCR assays and CT scans, the interval between the initial negative to positive RT-PCR results was 4 to 8 days.
Persze ez csak már előrehaladottabb állapotban lévő betegeknél működik, de egy idő után már úgyis csak velük foglalkoznak.
