摘　　要：目的 探讨CT及MR增强检查中对比剂外渗发生率及相关因素分析.方法 回顾性选取行CT及MR增强检查的连续病例234 728例,首先将对比剂外渗患者按性别分为女性组和男性组进行比较,进一步将2组分别按年龄分为<50岁亚组和≥50岁亚组,并进行亚组间比较.结果 本研究234 728例患者中,258例(0.11%)发生对比剂外渗,其中女性组对比剂外渗占62.02%,男性组对比剂外渗占37.98%.女性组对比剂外渗发生率(0.15%)显著高于男性组(0.08%),差异有统计学意义(P<0.001).进一步行亚组间分析,结果显示女性年龄≥50岁对比剂外渗亚组外渗发生率(0.18%)显著高于女性年龄<50岁亚组(0.07%),差异有统计学意义(P<0.001).女性年龄≥50岁对比剂外渗亚组外渗发生率(0.18%)显著高于男性年龄≥50岁对比剂外渗亚组(0.07%),差异有统计学意义(P<0.001).然而,男性<50岁和≥50岁对比剂外渗亚组间外渗发生率差异无统计学意义(P=0.23).结论 年龄≥50岁女性患者对比剂外渗发生率较高.Objective To investigate the incidence and related factors of contrast media extravasation during CT and MR enhanced examinations.Methods A retrospective collection of 234728 consecutive patients who underwent CT and MR enhanced examina-tions.Firstly,the patients with contrast media extravasation were divided into female group and male group according to gender for comparison.Further,the two groups were subdivided into<50 years old subgroup and≥50 years old subgroup according to age for inter-subgroup comparison.Results Among 234728 patients in this study,258(0.11%)developed contrast media extravasation.Among them,the female group accounted for 62.02%of contrast media extravasation,while the male group accounted for 37.98%.The incidence of contrast media extravasation in the female group(0.15%)was significantly higher than that in the male group(0.08%),and the difference was statistically significant(P<0.001).Further inter-subgroup analysis revealed that the incidence of contrast media extravasation in the female patients age≥50 years old subgroup(0.18%)was significantly higher than that in the female patients age<50 years old subgroup(0.07%),with statistical significance(P<0.001).The incidence of contrast media extravasation in the female patients age≥50 years old subgroup(0.18%)was significantly higher than that in the male patients age≥50 years old subgroup(0.07%),and the difference was statistically significant(P<0.001).However,there was no statistically significant difference in the incidence of contrast media extravasation between the male<50 years old and≥50 years old subgroups(P=0.23).Conclusion The incidence of contrast media extravasation is higher in female patients age≥50 years old.
