Male, 73 years old, lung adenocarcinoma with KRAS mutation. (a) A DESCT 70 keV image showed a solid nodule in the middle lobe of the right lung; the CT number at 70 keV was 11.49 Hu. (b) An iodine-based material-decomposition image reveals that the iodine concentration (IC) of the nodule is 9.06 μg/cm3 (L1). The IC of the aorta is 77.24 μg/cm3. The normalized IC (NIC) of this lung adenocarcinoma is 0.12 (9.06/77.24). (c) The effective Z material-decomposition image shows that the effective Z of the nodule is 8.15. (d) The graph shows the spectral HU curve of the nodule. Slope λ HU is 1.01. (e) The molecular pathological results showed KRAS mutations
