Chest X-ray

Application of Machine Learning to X-Ray and CT images in the diagnosis of COVID-19

By Ahmed El-Medany

Chest CT scans and X-ray images have been reported to have sensitivity values of 98 and 69%, respectively, with regards to diagnosing SARS-CoV-2 pneumonitis.

In this review by Mohammad-Rahimi et al, 105 studies reporting on machine and deep learning methods on CT and X-ray images in COVID-19 were analysed and compared. The accuracy of these methods ranged from 76% to more than 99%, suggesting the applicability of machine and deep learning methods in the clinical diagnosis of COVID-19; albeit with the requirement for multidisciplinary approaches in cases of clinical uncertainty.
