Radiologists at Vancouver General Hospital, the University of British Columbia, and Vancouver Coastal Health Research Institute are leading an international study to better predict the presence of COVID-19 based on CT scans. Radiologists, fellows, residents, and UBC medical students are collecting, analyzing, and labeling thousands of CT scans, and in some cases chest X-rays, from COVID-19 patients around the globe. Information gleaned from the scans will form the basis for an open source artificial-intelligence model to predict the presence, severity, and complications of COVID-19 on CT scans. The model will integrate clinical data to help support and supplement existing tools to improve patient care. For example, it could help physicians determine whether individuals are best treated at home or whether they may require hospitalization/ventilation. It will not replace current testing. The model will also assist in detecting similarities and differences in variations of patterns across different cultural and ethnic groups, and help researchers understand early and late stages of patterns of disease. It could also help flag those who may ultimately develop permanent lung damage/fibrosis. Researchers are confident this new tool will help them predict disease severity and its clinical impact in different patient populations.
Once developed, the new artificial-intelligence model will be piloted at Vancouver General Hospital with an aim to embed it in routine diagnostic procedures to improve the accuracy of COVID-19 diagnostics.
Funding for this project is provided by the UBC Community Health and Wellbeing Cloud Innovation Centre (UBC CIC), opened in January 2020 and powered by Amazon Web Services (AWS), as well as the AWS Diagnostic Development Initiative (DDI).

Above is the information needed to cite this article in your paper or presentation. The International Committee
of Medical Journal Editors (ICMJE) recommends the following citation style, which is the now nearly universally
accepted citation style for scientific papers:
Halpern SD, Ubel PA, Caplan AL, Marion DW, Palmer AM, Schiding JK, et al. Solid-organ transplantation in HIV-infected patients. N Engl J Med. 2002;347:284-7.
About the ICMJE and citation styles
The ICMJE is small group of editors of general medical journals who first met informally in Vancouver, British Columbia, in 1978 to establish guidelines for the format of manuscripts submitted to their journals. The group became known as the Vancouver Group. Its requirements for manuscripts, including formats for bibliographic references developed by the U.S. National Library of Medicine (NLM), were first published in 1979. The Vancouver Group expanded and evolved into the International Committee of Medical Journal Editors (ICMJE), which meets annually. The ICMJE created the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals to help authors and editors create and distribute accurate, clear, easily accessible reports of biomedical studies.
An alternate version of ICMJE style is to additionally list the month an issue number, but since most journals use continuous pagination, the shorter form provides sufficient information to locate the reference. The NLM now lists all authors.
BCMJ standard citation style is a slight modification of the ICMJE/NLM style, as follows:
- Only the first three authors are listed, followed by "et al."
- There is no period after the journal name.
- Page numbers are not abbreviated.
