目的:探讨急诊DSA下肢动脉造影质量控制方法。方法:对31例疑有下肢动脉病变的患者急诊行下肢动脉造影术,术中使用下肢动脉跟踪造影技术或旋转血管造影三维重建技术,经工作站图像后处理,观察图像质量及病变显示状态。记录检查时间及造影剂用量。结果:运用本方法检查采集图像,图像质量为理想,达到诊断要求。平均检查时间为21.6min。平均造影剂用量42.2ml。结论:本方法能在较短手术时间使用较少对比剂有效保证DSA下肢动脉造影的图像质量,提高诊断效率。
Objective: To investigate the quality control of lower extremity arteriography in emergency department of DSA. Methods: Thirty-one patients with suspected arterial disease of the lower extremity underwent emergency lower extremity arteriography. The lower extremity arterial follow-up angiography or rotational angiography three-dimensional reconstruction technique was used during the operation. The image quality and lesion status were observed after workstation image processing. Record examination time and contrast agent dosage. Results: The method used to check the acquisition of images, the image quality is ideal, to meet the diagnostic requirements. The average examination time is 21.6min. The average amount of contrast agent 42.2ml. Conclusion: This method can effectively guarantee the image quality of lower extremity arteriography in DSA with less contrast agent in shorter operation time, and improve the diagnostic efficiency.
