Researchers have found that chest C-rays could aid in rapid diagnosis of Covid-19. This method is more accurate and faster than conventional diagnosis.
The study used a unique scoring system to evaluate the severity of individual Covid-19 cases based on X-ray images.
Radiologists conducted a retrospective study of nearly 400 persons under investigation for Covid-19 in New Orleans. They reviewed the patients’ chest X-rays along with concurrent RT-PCR virus tests.
Using Covid-19 imaging patterns, they categorised each chest X-ray as characteristic, nonspecific, or negative in appearance for Covid-19.
The radiologists found a characteristic chest X-ray appearance is highly specific (96.6 percent) and has a high positive predictive value of 83.3 percent for SARS-CoV-2 infection in the setting of pandemic.
The ability to gauge the severity of COVID-19 lung infections can be used for escalation or de-escalation of care, especially in the ICU.
An automated tool can be applied to patients over time to objectively and quantitatively track disease progression and treatment response.
These results indicate the model’s ability to gauge the severity of COVID-19 lung infections could be used for escalation or de-escalation of care as well as monitoring treatment efficacy, especially in the ICU.
