CT images for cases in the RT-PCR-negative and RT-PCR-positive groups. The CT exams were performed on the 31st, 23rd, 24th and 22nd days from symptom onset for case 1–4, respectively. The two groups have a great overlap in original CT images and are difficult to be distinguished by eyes. After deep learning-based lobe and lesion segmentation, the radiomic feature maps of the lesion are calculated. For example, we can observe that original_firstorder_Minimum of the RT-PCR-negative group seems higher than the RT-PCR-positive group
