Imaging diagnosis and molecular detection for COVID-19

Abstract

The purpose of this study is to provide a systematic theoretical basis and technical support for the effective diagnosis and effective surveillance of Post COVID-19 epidemic. We systematically reviewed the development of the epidemic, collected data, and analyzed the medical imaging diagnostic methods and molecular detection techniques for clinical diagnosis of COVID-19 infected patients and the experience gained in clinical practice since the outbreak of the epidemic. Studies have shown that clinical suspected cases should be comprehensively analyzed in combination with clinical characteristics such as epidemiological contact history and imaging findings, and viral nucleic acid testing should be performed on respiratory or blood samples of suspected cases infected with new coronavirus(SARS-CoV-2). In clinical practice, patients with suspected COVID-19 pneumonia do not exclude the possibility of false negative test results. Real-time fluorescent RT-PCR is required to detect viral nucleic acid positive in order to fully confirm the diagnosis.
