Abstract:
Objective To investigate the incidence and related factors of contrast media extravasation during CT and MR enhanced examinations.Methods A retrospective collection of 234 728 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≥50years old subgroup according to age for inter-subgroup comparison.Results Among 234 728 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.
