Five different types of digital radiography systems were used to take posteroanterior CXR in Hospital-1 (Digital Diagnost, Philips; GC85A, Samsung; RADspeed, Shimadzu; CXDI, Canon; and XR220, Optima), four types in Hospital-2 (XR656, GE; Optima XR220, GE; Platinum 43, DMS; and CXDI, Canon), and five types in the eight community clinics (CXDI, Canon; DRX-Evolution, Carestream; uDR, United Imaging; Fluorospot Compact FD, Siemens; and Digital Diagnost, Philips). Supplementary Table 1 lists the DR equipments and acquisition parameters.
Optima xr220
Manufactured by GE Healthcare
Sourced in United States
The Optima XR220 is a digital radiography system designed for general radiographic applications. It features a high-frequency generator, a large-area digital detector, and advanced image processing capabilities. The system is intended to provide high-quality digital images for a variety of diagnostic procedures.

All noncontrast CT scans were obtained in the supine position at full inspiration using a multidetector CT scanner with 16 or more detector channels (Emotion 16, Somatom Sensation 64, Somatom Definition, Somatom Definition AS+, and Somatom Force; Siemens Healthineers, Erlangen, Germany). The CT tube voltage and current were 120 kVp, and a standard-dose or low-dose setting with automatic exposure control was used according to institutional protocols. Axial CT images were reconstructed with a slice thickness of 1 mm (3 mm in a minority of the cases) and a sharp reconstruction kernel. Chest radiographs were obtained using the following devices: DRX-Revolution (Carestream Health, Rochester, NY); Optima XR220 (GE Healthcare, Chicago, Ill); Fluorospot Compact FD (Siemens Healthcare, Erlangen, Germany); and CXDI (Canon, Tokyo, Japan). All chest radiographs consisted of single frontal view. Fourteen chest radiographs were taken at upright position with posteroanterior projection, and the remaining were taken with anteroposterior (AP) projection in supine position or sitting position.

All CT examinations were performed using a multi-detector CT scanner with 64 or more channels (Somatom Definition, Somatom Definition AS+, or Somatom Force, Siemens Healthineers, Erlangen, Germany). The detailed parameters for CT acquisition were as follows: tube voltage, 120 kVp; tube current, standard (reference mAs, 60–120) to low-dose (reference mAs, 30) with automatic exposure control; slice thickness, 1.0 mm; reconstruction interval, 1.0–3.0 mm; and a sharp reconstruction kernel. CT images were obtained with the patient in the supine position at full inspiration and without contrast medium.
All patients underwent a baseline digital anteroposterior chest radiography at full inspiration using a mobile chest radiograph machine (FLUOROSPOT Compact FD, Siemens Healthineers; DRX-Revolution Mobile X-ray System, Carestream Health, Rochester, NY, USA; or Optima XR220, GE Healthcare, Milwaukee, WI, USA).
Eight of the nine patients had parenchymal abnormalities on their baseline chest CT scans. In another patient, the baseline chest CT scan was normal, and parenchymal abnormalities were observed on a follow-up CT scan one week later. Accordingly, we analyzed eight baseline chest CT scans and one follow-up CT scan with abnormal findings of COVID-19 pneumonia.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
