Figure 2

A case of a calcified nodule not overlapping with the bone. (left) On the standard image, the evaluation of the presence or absence of calcification among readers was not consistent (confidence level of each reader: 1, 3, 2, 3 and 2, respectively). (right) In the soft tissue image, the nodule disappeared. All readers correctly evaluated it as calcified (confidence level of each reader: 1, 1, 2, 1 and 2, respectively).
