Role of radiology in RT-PCR negative COVID-19 pneumonia: Review and recommendations
Abstract
Currently, RT-PCR is the gold standard for diagnosing SARS-CoV-2 infection. However, due to the time-consuming laboratory tests and the low positivity rate of RT-PCR, it cannot be an ideal screening tool for infected population. In this review article, we have reviewed studies related to RT-PCR and CT chest and we would like to give our recommendations. Depending upon the patient's clinical symptoms and radiology imaging typical of viral pneumonia compatible with COVID-19 infection, clinicians need to consider isolation of these patients early even if the RT-PCR test is negative.
