Using CDFI to examine the models of TRAS were established before and after,observe the renal artery and each artery inside the TK, Emphasis to observe whetherthere are high speed color bloodstream signal in artificial TK arteriostenosis. Andachieve the pulse of artificial TK arteriostenosis、the renal artery and each arteryinside the TK, select the measure index include PSV、EDV and RI; Intravenous bolusinjection of contrast agent, Collect and store the continuous image which fromcontrast agent inner to disappear in TK and renal arterial. Open QLAB analysingsoftware, choose the region-of-interest, build TIC, measure and quantitativeanalysis on part parameter index.

在移植肾动脉狭窄动脉模型建立前后进行CDFI扫查，观察移植肾动脉及移植肾内各级动脉的彩色血流充盈情况，重点观察移植肾动脉人为狭窄处有无五彩镶嵌的高速彩色血流信号，并获取移植肾动脉人为狭窄处及肾动脉主干肾门处以及移植肾各级动脉的频谱，选取的测定指标包括：PSV、EDV、RI；经外周静脉注入造影剂，开启造影程序，采集并存贮造影剂开始注入至造影剂在移植肾动脉及移植肾内完全消失的连续动态声像图。

The length of stenosis was 02~10cm and the Grade 1 stenosis was one renal artery,Grade 2 six renal arteries,and grade 3 three renal arteries.MSCTA showed 6 kidneys dwindled with average length 71cm,which was 15cm less than normal kidneys.One case was accompanied by wallthickening and cavitary stenosis of abdominal aorta.The locations and extent of stenosis in 6 cases by XRA and by MSCTA were identical.We found renal arterial stenosis only in 5 of 8 cases and 6 dwindled kidneys by DUS.

MSCTA尚可见6例肾缩小，平均长径为71cm，低于健肾15cm以上；1例伴有腹主动脉壁增厚，管腔狭窄，直径约10cm；6例行腹主动脉或选择性肾动脉造影者与MSCTA显示肾动脉狭窄部位和程度完全一致。8例行彩色多普勒超声检查者，亦可见6例肾缩小，但仅5例显示肾动脉狭窄，左侧2条，右侧3条。

结果 34例患者中，颈动脉粥样硬化者29例，管腔轻度狭窄者10例，中度狭窄者12例，重度狭窄者5例，节段闭塞者2例；钙化斑块15例，非钙化斑块10例，混合斑块9例； CT值范围20-1140Hu，其中钙化斑块CT值220-1140Hu，非钙化斑块CT值20-73Hu；左侧颈总动脉起源异常者1例；颈动脉体瘤2例；椎动脉狭窄者4例。

1.Preliminary studys on the carotid artery parameters Detected by Intracavitary Convex Array ProbePurpose and SignificanceFinal results of The North American Symptomatic Carotid Endarterectomy Trial and the MRC European Carotid Surgery Trial displayed that carotid artery must be observed intimately when stegnosis degree is higher than 50%and it must have an operation or interventional therapy in time when stegnosis degree is higher than 70%.

1、腔内凸阵超声探头检测颈动脉参数的初步研究目的和意义北美有症状颈动脉内膜剥脱试验(The North American Symptomatic CarotidEndarterectomy Trial NASCET)和欧洲颈动脉手术试验(European Carotid SurgeryTrial，ECST)研究结果显示，当颈动脉狭窄程度超过50%时要密切观察病情变化，当狭窄程度超过70%时要及时手术或介入治疗，治疗后可大幅降低脑梗死的发生率。

结果 本组患者彩色多普勒超声检查对诊断颈动脉分叉部狭窄的敏感性和特异性分别为96.8％和80.6%，对锁骨下动脉狭窄为60.0%和98.7%，对椎动脉狭窄为33.3%和89.0%。

The accuracy of color ultrasound for stenosis of carotid bifurcation, subclavicular artery and vertebral artery were 93.0%, 92.8% and 82.1%.conclusion color ultrasound examination are effective for the diagnosis of carotid bifurcation sterosis, and less effective for the diagnosis of the subclavicular and vertebral artery stenosis because of the poor sensitivity.

彩色多普勒超声检查诊断颈动脉分叉部、锁骨下动脉和椎动脉狭窄的准确度为93.0%、92.8%和82.1%。结论彩色多普勒超声检查可作为诊断颈动脉分叉部位血管狭窄的有效方法；而其对锁骨下动脉及椎动脉狭窄的敏感性较低，诊断价值不大。

Results RAS(defined as ≥50% diameter stenosis) was detected in 22 of the 157 patients (14.01%) and 21 of the 81 patients with coronary artery disease(25.93%) who had at least one coronary artery of ≥50% diameter stenosis, while no RAS was found in patients whose coronary angiograms were normal.

结果 157例患者中，肾动脉狭窄发生率为14.0%；经冠状动脉造影证实的81例冠心病患者中，肾动脉狭窄的发生率为25.9%；冠状动脉造影完全正常的62例患者中，无1例有肾动脉狭窄。

This software can show the vessel stenosis, calcification and the relation with surrounding sclerotin clearly. It shows the stenosis section exactly and calculates the degree of stenosis automatically. Conclusion The 16-row CT angiography is no-trauma and can be the first choice in diagnosis of carotid artery stenosis.
