DECT analysis of thyroid cancer metastases to the lung. Solid lung tumor in the left lower lobe of the left lung (L1 - blue). Tumor densities − 3,67 ± 10.82 HU measured on invert gray maps improving visibility of the lesion A. High index of endogenous iodine accumulation 12.33 ± 2.10 × 100 µg / cm3 suggest metastasis of thyroid cancer B. Analysis of another nodule (L2 - red) also in the lower lobe of the left lung (C, D). Tumor density + 7.85 ± 8.49 HU C. Lower index of endogenous iodine accumulation 4.65 ± 3.28 × 100 µg / cm3 D. Comparison of X-ray absorption analysis by L1 and L2 in graphs showing ionizing radiation absorption curves as a function of photon energy in the range of 40–140 keV in the range of 5 keV (E)
