Methods forty patients with head/neck 16 slice CT angiograph were divided into two groups at random,each group has 20 cases, the plain scan and the CTP was performed before CTA to all 40 cases. Group A use CTP to obtain the peak time of contrasted artery as CTA delay time, and scan from head side to foot side. Group B use contrast media automatic bolus tracking to obtain delay time,scan from foot side to head side.two groups CTA images were collated.
使用16排螺旋CT对40例患者行头颈部CTA检查,随机分为两组,各20例,所有患者在CTA之前行脑CT平扫及脑CT灌注扫描,A组以CTP所显示的动脉峰值时间作为CTA的延迟时间,扫描方向为自头侧向足侧。B组使用造影剂浓度实时监控跟踪触发技术确定延迟时间,扫描方向自足侧向头侧扫描,两组CTA图像相对照。

Methods:Paticipants consisted of 32 simple VSD patients and 27 simple PDA patients excluded of any other diseases by physical examintation and electrocardiogram and x-ray. Patients were suggested echocardiography before and one week after the surgerys. Parameters such as Left ventricular ejection fraction、Fractional shortening、Left ventricular end-diastolic dimension、Left ventricular end-systolic dimension、Heart rate and Aortal velocity peak were measured.further more ,the Tei index which is originated from Pulse-wave Doppler and Tissue-Doppler Imaging were also calculated under ECG monitoring.
研究对象与方法:研究对象分别为排除其它心脏疾患的单纯动脉导管未闭患儿及单纯室间隔缺损患儿,手术治疗前后于心电监护下先行常规超声检查,获取心率、R-R间期、左室射血分数、主动脉峰值流速、左室收缩末期内径及左室舒张末期内径等值,并分别利用频谱多谱勒及组织多谱勒法测取患儿左室Tei指数(即PW-Tei及TDI-Tei),多次测量并取其均值。
