摘　　要：目的探讨子宫动脉开口在DSA图像上的“最易显示角度区间”。方法对12例患者子宫动脉开口部CTA三维容积重建（VR）、最大密度投影（MIP）成像进行标准正位和旋转观察，在正位分析出子宫动脉开口与其附着动脉的内外关系，在左右斜位获得能清晰显示子宫动脉开口的小角度区间。对27例患者子宫动脉开口部用同样方法于DSA造影过程中验证这个区间的准确性。结果41支子宫动脉开口位于附着动脉外侧，向对侧倾斜10°-40°可显示清晰；13支开口位于附着动脉内侧，向同侧倾斜30°-50°显示清晰；24支开口位于附着动脉前方，大角度倾斜40°-60°显示清晰。结论“最易显示角度区间”能很轻易、清晰显示子宫动脉开口。Objective To investigate the ＂optimal projecting angle range＂ for clearly displaying the opening of uterine artery on DSA. Methods Standard anterior-posterior （A-P） position and rotation obser- vation of the opening of uterine artery was conducted on CTA 3D VR and MIP images in 12 patients. The internal and external relationships between the opening of uterine artery and its attached arteries on A-P position images were analyzed, and the small projection angle range, on which the opening of uterine artery could be clearly revealed on the left and right oblique projection, was determined. The accuracy of the projection angle range used for clearly displaying the opening of uterine artery was evaluated by DSA examination in 27 patients with the same projection method. Results The openings of 41 uterine arteries were located at the lateral part of the attached arteries, which were clearly displayed on the images obtained by tilting 10°-40° toward to the opposite side. The openings of 13 uterine arteries were located at the medial part of the attached arteries, which were clearly displayed on the images obtained by tilting 30°-50° toward to the ipsilateral side. The openings of 24 uterine arteries were located at the anterior part of the attached arteries, which were clearly displayed on the images obtained by tilting 40°-60° toward to the opposite or ipsilateral side. Conclusion The use of ＂optimal projecting angle range＂ can easily and clearly display the opening of uterine artery on DSA.
