目的：评价冠状动脉瘘（coronary artery fistula，CAF）不同病变类型在双源CT（dual source computed tomography， DSCT）三维重建图像上的表现特征及瘘口显示情况。方法回顾性分析37例CAF患者的 DSCT资料，分别在轴位、冠状位、矢状位、曲面重建（ CPR）及容积再现（ VR）重建图像上观察病变，统计分析不同重建图像显示瘘口效果的差异。结果37例患者共有瘘口42处，显示瘘口方面：轴位、冠状位、矢状位及VR差异有统计学意义（ P＜0.05），轴位优于冠状位、矢状位及VR，冠状位优于VR（P＜0.05）。冠状动脉瘘至少5种以上方式，瘘口CT表现多样。结论双源CT三维重建图像能很好地显示CAF各种病变类型及瘘口的情况，各种重建技术显示冠状动脉瘘有其各自优势。
目的：評價冠狀動脈瘺（coronary artery fistula，CAF）不同病變類型在雙源CT（dual source computed tomography， DSCT）三維重建圖像上的錶現特徵及瘺口顯示情況。方法迴顧性分析37例CAF患者的 DSCT資料，分彆在軸位、冠狀位、矢狀位、麯麵重建（ CPR）及容積再現（ VR）重建圖像上觀察病變，統計分析不同重建圖像顯示瘺口效果的差異。結果37例患者共有瘺口42處，顯示瘺口方麵：軸位、冠狀位、矢狀位及VR差異有統計學意義（ P＜0.05），軸位優于冠狀位、矢狀位及VR，冠狀位優于VR（P＜0.05）。冠狀動脈瘺至少5種以上方式，瘺口CT錶現多樣。結論雙源CT三維重建圖像能很好地顯示CAF各種病變類型及瘺口的情況，各種重建技術顯示冠狀動脈瘺有其各自優勢。

Objective To evaluate the characteristics of coronary artery fistula( CAF) appeared as different types as well as the fistula opening on dual source CT( DSCT) three dimensional reconstruction images.Methods Retrospective analysis of DSCT data of 37 patients with CAF was performed.The CAF features were observed on the reconstructed images in the axial,coronal and sagittal sec-tions,as well as curve plantation reconstruction(CPR)and volume rendering(VR).Differences in different reconstruction images for showing the fistula were statistically analyzed.Results A total of 42 fistulas in 37 patients were displayed.The effects for the display of fistula had significance difference among axial,coronal and sagittal sections and VR reconstruction images(P<0.05).There was a sig-nificant difference between axial and coronal and sagittal sections and VR(P<0.05).Moreover,the axial was better than that of coro-nal,sagittal sections and VR while coronal section was better than that of VR(P <0.05).At least,there were five types of CAF dis-played various CT features on reconstruction images or 3D images.Conclusion The dual source CT 3D reconstruction images can well display different CAF types and the opening of fistulas.Various reconstruction techniques have their own advantages in showing CAF.
