DECT scans of the neck. Suspicious lymph node the same in Fig. 1 (ROI 2 - green), normal lymph node (ROI 1 - blue) and physiological muscle tissue (ROI 3 - red). Analysis with use of color maps depending on the concentration of the endogenous iodine. In pathological tissue, the concentration of accumulated iodine was the highest, it was 6.7 ± 4.17 × 100 µg / cm3, in muscle tissue it was 2.17 ± 2.36 µg / cm3, and the lowest in the normal lymph node 0.33 ± 3.81 × 100 µg / cm3 A, B. X-ray absorption analysis by pathological tissue (green), muscle (red) and normal lymph node (blue) on graphs showing ionizing radiation absorption curves depending on the photon energy in the range of 40–140 keV in the range of 5 keV based on actual values ​​C. Graphical representation of the distribution of dense measurements in ROI 1, ROI 2 and ROI 3 in the form of percentage distributions of pixels, one of the examples of the tumor. All analyses are performed because unique capabilities of the DECT modality
