X-Ray on patient chests are chest radiographs and are not as effective as CT scans. Radiograph abnormalities found in 10-12 days are similar to those found in a CT scan 6-11 days in.

Imaging tests cannot be used as the only reliable diagnostic tool to detect infection due to its lack of sensitivity. However, it can be useful in medical settings with limited resources where the virus is prevalent.

Radiographics Test / CT Imaging for COVID-19

The optimal diagnostic methods for COVID-19

Sensitivity and specificity of CT scans varies with COVID-19, therefore cannot be the determinant factor in diagnosing infection. Produce a medical image using multiple X-ray measurements from different angles of the patient's chest.

CT Scans

Chest radiograph

Diagnostic ultrasounds use high-frequency sound waves to produce imagery of structure in a patient's body. Lung ultrasound of COVID-19 patients show irregular pleural line and lesions in the lung. Ultrasounds have a 68-78% sensitivity and 85-92% specificity.
