Female, 39 years old, lung adenocarcinoma with EGFR mutation. (a) A DESCT 70 keV image showed a solid nodule in the inferior lobe of the left lung. The CT number at 70 keV was 49.66 HU. (b) An iodine-based material-decomposition image shows that the iodine concentration (IC) of the nodule is 12.18 μg/cm3; the IC of the aorta is 76.23 μg/cm3; the normalized IC (NIC) of this lung adenocarcinoma is 0.16 (12.18/76.23). (c) The effective Z material-decomposition image shows that the effective Z of the nodule is 8.35. (d) The graph shows the spectral HU curve of the nodule; slope λ HU is 0.82. (e) The molecular pathological results showed EGFR mutations
