COVID-19 Chest Radiography Scoring Protocols

At Nottingham University Hospitals, single-view posteroanterior or
anteroposterior chest radiography was routinely performed for patients admitted
with proven or suspected SARS-CoV-2 infection. The first chest radiographic
examination performed during the admission relating to RT-PCR was selected for
analysis. During the early part of the pandemic, reporting was not uniform, and
no specific scoring system was used. Thus, all chest radiographs were reassessed
by using the RALE (22 (link)), Brixia (7 ,21 (link)), and percentage opacification scores (18 (link)). Table
E1 (online) and Figure 1 describe these scoring systems. Chest radiographs
were interpreted by using a Jusha monitor (Nanjing Jusha Commercial and
Trading), with a picture communication and archiving system (GE Healthcare).
Radiography was performed by using dual-detector system (DigitalDiagnost;
Philips), digital system (Ysio Max; Siemens), and the FDR Nano Mobile (Fuji)
system.

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.
