600例头颈CTA主动脉达峰时间分析
|
摘要
目的:探究头颈CTA主动脉达峰时间的影响因素。方法:回顾性分析2016年1月—2018年1月于我院进行头颈部CT血管成像检查未见异常的600例患者的扫描参数,采用独立样本t检验和单因素相关分析患者的性别、年龄、体重、身高、心率、收缩压、舒张压、体质指数(BMI)、体重用药量以及扫描位置对达峰时间的影响。结果:患者头部与颈部CTA主动脉血管达峰时间无明显差距(P>0.05);女性患者头颈CTA主动脉达峰时间快于男性患者(P <0.05);头颈CTA主动脉达峰时间与患者的体重、身高、舒张压及体质指数呈正相关(P <0.05),与患者的年龄、心率、收缩压及体重用药量不相关(P> 0.05)。结论:CTA检查结果未见异常时,患者的性别、体重、身高、舒张压及体质指数是影响患者头颈CTA主动脉达峰时间的主要因素,在对患者进行头颈CTA时,可以根据患者的体质指数适当调控对比剂注射时的体重用药量及延长扫描时间,达到用最小量造影剂获得最佳诊断图像的效果。
Objective To explore the factors influencing the time of head and neck CTA aorta. Methods Retrospective analysis of the scanning parameters of 600 patients with no abnormal head and neck CT angiography in our hospital from January 2016 to January 2018, using independent sample t-test and single factor correlation analysis of the patient's gender, age, weight, height, heart rate, systolic pressure, diastolic blood pressure, body mass index(BMI), weight, dose and the influence of scanning position to reach the peak time. Results There was no significant difference between the head and the CTA aorta of the neck(P >0.05). CTA aorta of female patients was faster than that of male patients(P<0.05). Patients with head and neck CTA aorta reaches the peak time and the weight, height, diastolic blood pressure and body mass index were positively correlated(P < 0.05), and the patient's age, heart rate and systolic blood pressure and weight dose not related(P > 0.05). Conclusion CTA inspection result without changing the geomagnetic, patients' gender, weight, height, diastolic blood pressure and bmi are the main factors of patients with head and neck CTA aortic tmax, in patients with head and neck CTA, can according to body mass index in patients with proper regulation and dose of contrast medium injection weight to extend the time of scanning, to use the minimum contrast agents to obtain the best diagnostic image effect.
