手背静脉留置技术在多层螺旋冠状动脉CT血管检查中的应用
|
摘要
目的探讨手背静脉留置技术在冠状动脉CT血管造影检查中的应用价值。方法 103例冠脉检查患者,根据对比剂不同注射方式随机分成两组:A组(常规肘正中静脉注射),B组(手背静脉注射),行冠状动脉CT检查,所得数据经后处理工作站重建。对所得冠状动脉段图像质量进行评分,并测量室间隔CT值及主动脉根部、左主干及右冠状动脉起始部血管腔内CT值、噪声(N),同时计算信噪比(SNR)、对比噪声比(CNR)。结果 2组间图像质量差异无统计学意义(P> 0.05);2组血管腔强化CT值仅右冠状动脉起始部差异有统计学意义(P <0.05),余主动脉根部、左主干血管强化CT值及噪声、SNR、CNR差异均无统计学意义(P> 0.05)。亚组分析显示不同体质量指数组患者SNR、CNR均无统计学意义(P> 0.05)。结论手背静脉留置技术可得到较好的冠状动脉CT图像。
Objective To study the application of dorsal hand venous indwelling technique in coronary artery CT angiography( CTA). Methods 103 patients were randomly assigned to Group A(median cubital vein)and Group B( dorsal hand vein) according to different site of intravenous injection before undergoing multi-slice spiral CT( MSCT) coronary angiography and the data were reconstructed by post processing workstation. Coronary CT value and image noise were measured in aortic root, origin of left main coronary and right coronary artery,meanwhile signalnoise ratio(SNR) and contrast noise ratio(CNR) were calculated. Results There was no significant difference in image quality between Group A and Group B(P > 0.05). There was significant difference in right coronary artery CT value between the two groups(P < 0.05), while the image noise, SNR, CNR showed no significant difference(P > 0.05). Subgroup analysis showed that SNR and CNR in patients with different BMI showed no significant difference(P > 0.05). Conclusions Dorsal hand intravenous indwelling technique is recommended to be the second choice to obtain higher quality CT image.
