Table 1.
Comparison of scores for the two sets of CT images.
Fig 1.
The scatterplot of diagnoses for the two sets of images of each case.
Spots on the solid line represents that the diagnoses for the two sets of images are the same. The more spots overlap, the bigger the size of spot. The counts of overlapped spots and the P value are marked.
Fig 2.
The scatterplot of follow-up recommendations for the two sets of images of each case.
Spots on the solid line represents that the follow-up recommendations for the two sets of images are the same. The more spots overlap, the bigger the size of spot. The counts of overlapped spots and the P value are marked.
Fig 3.
Scatterplot of the mean diagnostic confidence for each nodule.
The solid line represents a hypothetical line indicating that the confidence of ultra high-resolution computed tomography (UHRCT) images is equivalent to that of conventional high-resolution computed tomography (CHRCT) images.
