Insights
Patients with normal chest CT scans can still carry SARS-CoV-2, the virus causing COVID-19. Clinical management is crucial for suspected cases, even with negative imaging, to prevent virus transmission.
Area of Science:
- Infectious Diseases
- Radiology
- Public Health
Background:
- SARS-CoV-2 can be carried by asymptomatic individuals and those with normal chest CT findings.
- Negative chest CT results may lead to underdiagnosis and potential virus transmission.
- Early identification and management are critical for controlling infectious diseases.
Abstract:
Asymptomatic patients and infected patients with normal chest CT imaging are considered carriers of SARS-CoV-2. Before a diagnosis of coronavirus disease 2019 (COVID-19) is made, these patients with negative chest CT findings may be ignored, causing the possibility of virus transmission. For patients with suspected infections, reliable epidemiological information and clinical symptoms, clinical management is necessary even when the chest CT is negative.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
