摘　　要：目的探索CT快速扫描一站式双下肢动静脉血管成像的可行性和应用价值。方法对110例患者采用Revolution CT双下肢扫描,A组采用快速扫描间接法CTA和直接法CTV(CTA 39例,一站式成像32例),B组采用常规扫描间接法CTA(40)例,C组采用常规扫描间接法CTV(31例),A组动脉与B组动脉血管密度和图像质量比较,A组静脉与C组静脉血管密度和图像质量比较。结果A、B两组下肢大腿动脉血管CT值均无显著差异,两组膝部动脉、小腿动脉、踝部动脉血管CT值有显著差异,其中B组膝部动脉、小腿动脉、踝部动脉血管CT值均低于A组;A、B两组间下肢动脉血管图像质量相似,无显著差异。A组下肢静脉横断面示全部密度较高,无假充盈缺损,与C组比较A组扫描下肢静脉图像质量更好,有显著差异。结论CT快速扫描间接法双下肢动脉CTA和直接法双下肢静脉CTV一站式成像,辐射剂量显著减少,一次检查即可对双下肢动静脉病变分析,值得临床推广应用。Objective To explore the feasibility and application value of CT rapid scanning one-stop arteriovenous angiography of lower limbs.Methods 110 patients were scanned with Revolution CT double lower limbs.Group A used rapid scanning of indirect CTA and direct CTV(39 CTA,32 one-stop imaging),Group B used conventional scanning of indirect CTA(40 cases),Group C used conventional scanning of indirect CTV(31 cases),Group A compared the arterial density and image quality with Group B,and Group A compared the venous density and image quality with Group C.Results There was no significant difference in the CT values of the thigh artery of the lower limbs between group A and group B.There were significant differences in the CT values of the knee artery,calf artery and ankle artery between the two groups.The CT values of the knee artery,calf artery and ankle artery in group B were lower than those in group A;The image quality of lower limb artery between group A and group B was similar,and there was no significant difference.The cross section of the lower limb veins in group A showed that the density of all the lower limb veins was high,and there was no false filling defect.Compared with group C,the quality of the lower limb veins in group A was better,with a significant difference.Conclusion The radiation dose of one-stop CT scan of indirect CTA and direct CTV of both lower extremity arteries is significantly reduced,and one examination can analyze the arteriovenous lesions of both lower extremity,which is worthy of clinical application.
