We evaluated the generalization capability of deep neural networks (DNNs),\ntrained to classify chest X-rays as COVID-19, normal or pneumonia, using a\nrelatively small and mixed dataset.\nWe proposed a DNN architecture to perform lung segmentation and\nclassification. It stacks a segmentation ...
Series chest x-rays in an 80-year-old woman with COVID-19 pneumonia. a Chest x-ray obtained on illness day 5 showed peripheral GGO in the LLZ (score 1). b Chest x-ray obtained on illness day 7 showed increase extent of the GGO diffusely involving the left lung (score 4). c Ches...
It is important to note, however, that chest X-rays are not very sensitive for COVID-19 and that patients who are highly suspicious for COVID-19 viral pneumonia should probably get a chest CT even if their initial chest X-ray is negative. 通常,当某个患者出现COVID-19的症状,如发热、...
