Abstract：Objective To investigate the value of the optimal monochromatic technology of gemstone spectral imaging in dispalying the supply artery of thyroid tumors.Methods 35 patients with thyroid tumors confirmed by surgery and pathology were analyzed retrospectively,all the patients underwent the neck dual-phases contrast enhancement scanning with the GSI model.After scanning,the machine reconstructed the 140 kVp mixed energy images,70 keV single images autonatically,and then the optimal monochromatic images were obtained by the GSI Viewer software.Finally,a total of 44 eligible supply arteries were involved,and the CNR,SNR,subjective scores of them in each groups were analyzed by one-way ANOVA method.Results CNR of the optimal monochromatic group,the 70 keV group,and the 140 kVp mixed energy group were 15.75 ±4.64,18.78 ±4.87 and 23.36± 6.58 respectively;SNR were 23.54 ± 5.03,27.27 ± 5.32 and 30.85 ± 6.90 respectively;Subjective scores were 3.13 ±0.51,3.77 ±0.63 and 4.36 ±0.52,respectively.CNR,SNR and subjective scores had significant difference among groups (F=21.87,17.41 and 21.87,respectively,P ＜ 0.05),and those in the optimal monochromatic group were superior to the 70 keV group and the 140 kVp mixed energy group.Conclusion The optimal monochromatic mode can improve the CTA quality of the thyroid tumor supply arteries.
