Best practice advises that CT chest is not used to diagnose COVID-19, but may help assess for complications. The non-specific imaging findings are most commonly of atypical or organizing pneumonia, most commonly with a bilateral, peripheral, and basal predominant distribution.
Here a comparison of a chest radiograph and CT image. The ground glass opacities in the right lower lobe on the CT (red arrows) are not visible on the chest radiograph, which was taken 1 hour prior to the CT-study (1).
13 Φεβ 2020 · A new deep learning pipeline to detect Covid-19 on chest X-ray images using local binary pattern, dual tree complex wavelet transform and convolutional neural networks
16 Ιουλ 2020 · In a series of 1099 hospitalised patients with laboratory confirmed covid-19 from across China, of the 274 patients who had chest radiography on admission 162 (59.1%) showed abnormalities, most commonly “bilateral patchy shadowing” (n=100, 36.5%).
Chest imaging, with X-ray and high-resolution computed tomography (HRCT), plays an important role in the initial evaluation and follow-up of patients with COVID-19 pneumonia. Chest imaging can also help in assessing disease severity and in predicting patient’s outcome, either as an independent factor or in combination with clinical and ...
