Abstract
Objective:To measure the iodine concentration of the living the normal value base on material imaging measure-ment,and to study its accuracy.Methods:Total of 76 cases of suspected cervical or thyroid disease underwent gemstone spectral ima-ging.Then the imagine data were transmitted to AW 4.4 station to obtain monochromatic images of optimal contrast to-noise ratio (CNR)and iodion-based images with GSI Viewer.Iodine,water concentration of ROl in thyroid tissue was measured.In addition,35 cases of surgical specimens of nodular goiter were collected,and select normal thyroid tissue of adjacent nodules.The iodine content of samples was measured by As-Ce-Catalytic spectrophotometry.Relationship between iodine and water concentration with it were ana-lyzed.Results:The difference of iodine concentration between male and female patients was statistically significant (P <0.05 ).There was no statistical difference between 40 -60 group and >60 group(P >0.05),while differences between other groups were statistically significant (P <0.05 and P <0.01 ).The comparison among groups of water concentration were not statistically significant(P >0.05). In nodular goiter group,the iodine concentration of isolated specimen is 0.173-0.64 mg /g,mean(0.357 ±0.064)mg /g.Statistical a-nalysis showed correlation (r =0.820,P <0.01 )between iodine concentration (0.28 -2.31 mg /mL,mean(1 .38 ±0.56)mg /mL) and the iodine concentration of isolated specimen.There was no correlation (r =0.064,P >0.05 ) between water concentration (1 040.73 -1 067.17 mg /mL,mean(1 055.93 ±1 1 .16 )mg /mL)and the iodine concentration of isolated specimen.Conclusion:Gemstone spectral imaging can be more direct and more accurate quantifying of iodine concentration of normal thyroid.This can provide reference for the diagnosis of thyroid diseases.关键词
