The diagnostic pathway for COVID-19
RT-PCR is the gold standard to confirm COVID-19. However, studies have shown that early stage of COVID-19 can be undetected by the lab test, where CT imaging is more likely to detect COVID-19 in early stages. CT imaging has shown to be a highly sensitive method to detect COVID-19. It is a reliable, practical and rapid method to detect and assess COVID-19. X-ray, although not as sensitive as CT, is also used among patients presenting COVID-19 symptoms especially since it uses less radiation, and is often cheaper, quicker and easier to use than CT and more available in resource-constrained settings. Further benefits of X-ray are that they can be portable and thus used at the patient’s bedside. The power of radiology in this crisis is highlighted as such: a positive diagnosis from radiology is definitive, even when a lab test is negative. Furthermore, radiology is an optimal method when it comes to assesing the progression of COVID-19 cases.

Why use artificial intelligence?
- Reduce the workload of the health workforce
- Enable quicker detection, therefore allowing for higher throughput
- Enhance diagnostic infrastructure in resource constrained settings
- Alleviate the burdens related to pathology tests.
- Quantify disease progress and recovery
