摘　　要：目的探讨乳腺导管造影中不同浓度碘对比剂对图像质量的影响。方法选择2008年6月-2009年10月50例非妊娠哺乳期的乳头溢液患者行数字平板X线成像(DR)的乳腺导管造影检查。将患者的左乳设为L组,右乳设为R组。L组使用碘离子浓度为370 mg/m L的碘帕醇注射液,R组使用碘离子浓度为300 mg/m L的碘帕醇注射液。对两组图像进行质量评分和平均密度评估。结果 L组和R组的图像质量评分均为(2.8±0.2)分,差异无统计学意义(P>0.05)。L组和R组乳房轴位的主导管内平均密度值分别为(4 020.25±96.26)、(3 984.75±117.67)HU,侧斜位的主导管内平均密度值分别为(4 067.13±24.69)、(3 971.25±167.32)HU,侧位的主导管内平均密度值分别为(4 058.88±52.07)、(4 034.75±67.54)HU,组间比较差异无统计学意义(P>0.05)。结论乳腺导管造影中使用不同浓度(300、370 mg/m L)的非离子型碘对比剂对诊断的影响无明显差异。Objective To explore the influence of different concentrations of iodinated contrast agent on image quality of galactography.Methods Between June 2008 and October 2009,50 non-pregnancy and non-lactation patients with mammary papilla discharge underwent breast galactography with digital mammography.All the patients＇ left breasts were in group L,and right breasts were in group R.The iohexol concentration of iopamidol injection was 370 mg/mL in group L and 300 mg/mL in group R.The image quality and the evaluation of average density of the two groups was analyzed and compared.Results The image quality score of group L and R was 2.8±0.2（P〉 0.05）.The mean density of main duct of breast axial view in two groups was（4 020.25±96.26） and（3 984.75±117.67） HU,respectively;the mean density of the lateral oblique view was（4 067.13±24.69） and（3 971.25±167.32） HU,respectively;the mean density of the lateral view was（4 058.88±52.07） and（4 034.75±67.54） HU,respectively.There was no significant difference between the two groups（P〉 0.05）.Conclusion No obvious difference between the two concentrations of non-ionic iodinated contrast agents（300 and 370 mg/mL） in galactography diagnosis is found.
