AI-Assisted Screening COVID-19 Solution

In China, RT-PCR is the gold standard for detecting COVID-19. However, according to the experience also research as well, RT-PCR has some limitations.

“COVID-19 RT-PCR sensitivity may be as low as 60-70%; therefore patients with pneumonia due to COVID-19 may have lung abnormalities on chest CT but an initially negative RT-PCR. ”

“In a series of 51 patients with chest CT and RT-PCR assay performed within 3 days, the sensitivity of CT for COVID-19 infection was 96% compared to RT-PCR sensitivity of 71% (p<.001).”

Because of that, Hospitals in China do CT chest screening first. This is the part AI help radiologists to better interpreting images. Huawei partner “HY Medical” team collected 4000+ of NCP data in real time and obtained precise labelling from the professional panel of doctors to use as the base for our deep learning algorithm. It can detect suspected contours of pneumonia and give probability of NCP to Chinese radiologist as a reference to help them screening and make a diagnosis. After that, they take imaging findings with RT-PCR test results and other clinical information together to confirm a COVID-19 case.
