Abstract: Objective:To investigate the value of iodine concentrations determined by single source dual energy CT in evaluating the blood supply of fatty liver and focal fatty sparing of liver.Methods:Twenty patients underwent spectral CT scan and were diagnosed with fatty liver and focal fatty sparing,were retrospectively collected in this study.The Non-CE CT value,three-phase CE CT value and iodine concentrations of fatty liver background (FLB) and focal fatty sparing (FFS) were measured by two radiologists.Three-phase enhanced ratio was also calculated for FLB and FFS.The bland-altman,linear regression analysis and intraclass correlation coefficient (ICC) were used to evaluate the consistency of measurements taken by two observers.The quantitative data between FLB and FFS were compared by using paired-samples t test and rank sum test.Results:The consistency of measurements between the observers was rated very well (ICC > 0.75).On the unenhanced and enhanced CT scan,the mixing energy CT value and iodine concentrations of FFS were higher than those of FLB (P < 0.001).The three-phase enhanced ratio of FLB was higher than those of FFS,and there was statistical significant difference (P =0.006,P < 0.001 and P < 0.001,respectively).There was no significant difference in the three-phase enhanced ratio of iodine concentrations between FLB and FFS groups (P-0.455,0.279 and 0.279,respectively).Conclusion:The enhanced ratio of iodine concentrations is more reliable in the evaluation of blood supply of fatty liver and focal fatty sparing,and this proved that the appearance of blood supply of fatty liver and focal fatty sparing is about the same.Thus,it provides a certain basis to differentiate between FFS and atypical hypovascular hepatic tumors.
