Tumor size in patients with severe pulmonary emphysema might be underestimated on preoperative CT

ConclusionsTumor size is significantly smaller on preoperative CT in patients with severe emphysema compared to patients without emphysema, especially in the case of large tumors. MPR measurement using the widest of three dimensions should be used to select T-stage for patients with severe emphysema.Key Points•The presence of emphysema affects the accuracy of tumor size measurements on CT.•Compared to patients without emphysema, the tumor size in severe emphysema patients tends to be measured smaller in preoperative CT than the pathological specimen.•This trend is more evident when large tumors are measured on axial CT images alone.
