DECT images in a 63-year-old man with squamous cell carcinoma in the left lower lobe (Ki-67, high expression; TTF-1, negative). In the volumetric spectral analysis (A), the whole lesion was completely outlined in the mediastinal window, with a volume of 13.35 cm3 in the arterial phase and a volume of 13.52 cm3 in the venous phase. In the conventional spectral analysis (B), the circle indicates the region of interest outlining the lesion, with a ROI of 6.81cm2; VOI, the volume of interest; ROI, region of interest; AP, arterial phase; VP, venous phase
