【摘要】：目的对比增强磁共振血管成像(CE-MRA)和CTA对早期宫颈癌供血血管的显示效果。方法回顾性分析30例经病理证实为早期宫颈癌患者术前的CE-MRA和CTA图像,评估CE-MRA和CTA对双侧子宫动脉主干的起源及连续性显示的一致性,同时评估两者对子宫动脉下行支的显示率。结果 CE-MRA和CTA对子宫动脉主干起源显示清楚、血管显示清楚且连续性不中断为50支,子宫动脉主干起源显示清楚、血管显示不清楚为5支,CE-MRA和CTA对于子宫动脉的起源及连续性的显示一致性良好(Kappa=0.80,P0.05)。MRA对子宫动脉下行支的显示率约为55.00%(33/60),低于CTA对子宫动脉下行支的显示率[73.33%(44/60)],差异有统计学意义(χ~2=26.22,P0.01)。结论 CTA和CE-MRA均可良好地显示术前早期宫颈癌子宫动脉主干的起源及连续性,CTA对于早期宫颈癌患者子宫动脉下行支的显示较CE-MRA更具优势。
[Abstract]:Objective to compare the effect of enhanced magnetic resonance angiography (CE-MRAA) and CTA on the blood supply vessels of early cervical carcinoma.Methods CE-MRA and CTA images of 30 patients with pathologically proved early cervical cancer were analyzed retrospectively to evaluate the consistency of CE-MRA and CTA in the origin and continuity of bilateral uterine artery trunk.At the same time, the display rate of the descending branch of uterine artery was evaluated.Results CE-MRA and CTA showed the origin of the main uterine artery clearly, and the blood vessel showed clearly and uninterrupted in 50 branches, and the origin of the main uterine artery was clear.There was a good consistency between CE-MRA and CTA in displaying the origin and continuity of uterine artery. The display rate of descending branch of uterine artery was about 55.00% -MRA, which was lower than that of CTA (73.33444460%), and the difference was statistically significant (蠂 ~ (2) ~ (2) ~ (26) ~ (2) ~ (2) ~ (2) ~ (2) ~ (2) ~ (2) ~ (2) ~ (2) ~ (2) ~ (2) ~ (2) ~ (2) ~ (2) ~ (2) ~ (2) ~ (2) ~ (26) ~ (22) ~ (?)Conclusion both CTA and CE-MRA can show the origin of uterine artery trunk in early cervical cancer before operation and the continuity of CTA in displaying the descending branch of uterine artery in early cervical cancer patients. It is superior to CE-MRA in displaying the descending branch of uterine artery in patients with early cervical cancer.
