Abstract:
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.
