Figure 1.

Examples of tumors from our study. (a) and (b) are examples of tumors that were judged to have met the QIBA measurability criteria, while (c) and (d) were not found to meet the criteria. Image (c) was excluded because it demonstrates a large attachment to other pulmonary structures and (d) was excluded because it demonstrates a highly invasive structure where the boundary between tumor and non-tumor is not well demarcated.
