研究目的: |
本研究旨在评估钆对比剂在CTA双能量成像扫描中的安全性和有效性,为临床提供更安全的替代选择。通过比较钆对比剂与传统碘对比剂在CTA中的图像质量,评估其安全性,包括过敏反应和肾功能影响,同时探索其在特定患者群体中的适用性。 |

|
Objectives of Study: |
This study aims to evaluate the safety and efficacy of gadolinium contrast agents in CTA dual-energy imaging scans, providing a safer alternative for clinical use. By comparing the image quality of gadolinium contrast agents with traditional iodine contrast agents in CTA, the study assesses their safety, including allergic reactions and renal function impacts, while also exploring their applicability in specific patient groups. |
