Computed Tomographic Imaging Of 3 Patients With Coronavirus Disease 2019 Pneumonia With Negative Virus Real-Time Reverse-Transcription Polymerase Chain Reaction Test

We reported computed tomographic (CT) imaging findings of 3 patients with coronavirus disease 2019 (COVID-19) pneumonia with initially negative results before CT examination and finally confirmed positive for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by real-time reverse-transcription polymerase chain reaction assay.
