Correlation between tumor size and blood volume in lung tumors: a prospective study on dual-energy gemstone spectral CT imaging.
Bottom Line: DECT was taken for pretreatment evaluation.The average value of the iodine density was significantly lower in larger tumors.The average water density and the average CT value were significantly correlated, but the average iodine density and the average CT value showed no significant correlation.

Mentions: The average CT value and the average water density were slightly increased as the tumor become larger, but no statistically significant difference was observed. On the other hand, the average iodine density was decreased in large tumors. Significant difference in average iodine density was noted between tumors of from 2–3 cm and ≤2 cm (P < 0.05), and between those of >3 cm and ≤2 cm (P < 0.05), as shown in Fig. 2.Fig. 2.
