Chest x-rays can predict Covid-19

Issue

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.

 

Background

The study used a unique scoring system to evaluate the severity of individual Covid-19 cases based on X-ray images.

 

Details

  • 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.
