目的：探讨256层螺旋 CT 回顾性心电门控扫描技术在膈下动脉(IPA)成像中的价值。方法将本院80例行腹部 CT血管成像(CTA)患者随机分为常规腹部 CTA 扫描组(常规组)和采用回顾性心电门控技术扫描组(门控组),统计分析2组显示IPA 各级血管的能力及 IPA 各级血管的图像质量。结果80例均扫描成功。常规组40例共显示右 IPA 和左 IPA 各40例,IPA一级、二级、三级及四级血管分别为80、73、59例及43例；门控组40例共显示右 IPA 和左 IPA 各40例,IPA 一级、二级、三级及四级血管分别为80、79、71例及65例。常规组和门控组 IPA 一级血管的显示及图像质量差异无统计学意义(P >0.05),常规组和门控组 IPA 二级、三级、四级血管的显示及图像质量差异有统计学意义(P <0.05)。结论256层螺旋 CT 回顾性心电门控扫描技术行 IPA 成像是可行的,明显提高 IPA 分支的显示和图像质量。

Objective To evaluate the value of retrospective ECG-gated 256 slices spiral CT technique in the scanning of inferior phrenic artery (IPA).Methods 80 patients with underdone abdominal CTA were divided randomly into two groups (40 patients each)as regular abdominal CTA scanning group and retrospective ECG-gated technique group.And further analysis was done to evaluate the display of IPA branches and the image quality.Results 80 patients were all scanned successfully.40 cases LIPA and 40 cases RIPA were showed in the regular group.80 cases showed 1st level branches of IPA,73 cases with 2nd level,59 cases with 3rd and 43 ca-ses showing 4th level.40 cases LIPA and 40 cases RIPA were showed in ECG-gated group.And the numbers of IPA branches levels were 80,79,71,65,respectively.There is no significant difference in the ability of showing the1st level IPA or their image quality between those two groups (P >0.05);and there is a statistical significance in the ability of showing other levels of IPA and their im-age quality.Conclusion It is feasible that we use retrospective ECG-gated 256 slices spiral CT scanning technique to show the IPA. And it could improve the ability of showing the IPA branches as well as the image quality.
