Results: l、The optimal scan parameters for chinese people are flow rate of 3. 0 mL/sec and total injection 125ml. 2、Visibility of coronary arteries and segments: only those proximal and mid segment is image quality sufficient to allow a semiquantitative assessment. 3、Detection of Atherosclerotic Plaque: CT coronary imaging revealed highest sensitivities for the detection of atherosclerotic wall changes the sensitivity of stenoses was 86. 3％. 4、MSCT coronary angiography is easy to prove the entire anatomic structure of coronary and it is an effective technique for evaluating coronary patency. 5、MSCT coronary angiography correctly identified all normal controls and all patients with coronary artery fistula. The anatomic course of the coronary artery fistula was correctly classified. 6、A11 severe lesion could be visualised by

结果：1、不同的扫描技术参数所获得的造影图像质量不同，注射速率3.0ml/s组以及125m1对比剂总量组比较适合国内患者。2、多层螺旋CT冠状动脉造影可显示冠状动脉的主要分支，尤其是冠状动脉的近、中段，显示率在90％以上。3、多层螺旋CT冠状动脉造影对狭窄病变的敏感性为87.3％，能检出冠状动脉造影不易发现的细小斑块，判断狭窄的原因及斑块的特征。4、多层螺旋CT冠状动脉造影可显示搭桥血管的形态、位置及通畅程度，显示桥血管及支架的内腔，安全便捷。5、多层螺旋CT显示冠状动脉畸形准确性高（3/3），多种成像方法可弥补冠状动脉造影显示的不足。6、仿真内窥镜可显示冠状动脉内膜和内腔，显示狭窄斑块的性质。

The optimal reconstruction windows of patients with stable HR(≤75 bpm and≥91 bpm) were concentrated in 71%,ranged from 65%-80%, and in 41%,ranged from 32%—50%,respectively.The prospectively ECG-gated DSCT coronary angiography can be used in patients with stable HR(≤75 bpm and≥91 bpm) in abstract.②To explore the clinical application of prospectively ECG-gated transverse DSCT coronary angiography.Methods Two hundreds patients[Body mass index:23-25 kg/m~2,122 patients(average HR≤75 bpm),78 patients(average HR≥91 bpm)]with suspected or known coronary artery disease underwent prospectively ECG-gated transverse DSCT coronary angiography,among them,30 patients underwent selectively coronary angiography,grouping them into 2 groups according to the average HR of scanning.Group A(17 cases,HR≤75 bpm),group B(13 cases, HR≥91 bpm),the DSCTA results were compared with SCAG.Then,calculate the accuracy of patients in each group and evaluate the agreement of accuracy between DSCTCA and SCAG by Kappa statistics.

方法回顾性分析200例行适应性前瞻性心电门控双源CT冠状动脉血管成像的患者(排除扫描过程中，屏气配合差，出现心律不齐的患者及行支架置入或搭桥术后复查的患者)，包括屏气时平均HR≤75 bpm患者122例，HR≥91 bpm患者78例；其中30例同期行选择性冠状动脉血管造影，按屏气时HR将其分为2组，A组17例：HR≤75 bpm，B组13例：HR≥91 bpm，分别与金标准SCAG对照，计算2组患者的阳性诊断准确率，应用SPSS 13.0统计学软件，利用Kappa检验比较每组患者的2种诊断方法诊断结果的一致性，利用两样本率x~2检验，比较2个心率组间的诊断准确率有无明显统计学差异，并计算此30例患者的平均有效辐射剂量。

Accuracy between two groups was calculated byχ~2 test.Calculate the average effective radiation dose of the 30 patients.Results In group A,seventeen patients underwent both DSCT coronary angiography and SCAG,among 255 segments of 17 patients,105 lesion sites of 70 segments were diagnosed stenosis or obstruction,of them,95 lesion sites were confirmed by SCAG.The accuracy of DSCTCA was 90.48%.The agreement of two methods have a high agreement(Kappa =0.853).In group B,13 patients underwent both DSCT coronary angiography and SCAG,among 195 segments of 13 patients,73 lesion sites of 57 segments were diagnosed stenosis or obstruction, of them,65 lesion sites were confirmed by SCAG.The accuracy of DSCTCA was 89.04%.The agreement of two methods have a high agreement(Kappa =0.835). There was no significant difference(χ~2=0.098,p＞0.05) between the accuracy of two groups.The effective radiation dose of 30 patients was 3.67±0.43 mSv.Conclusion Compared with SCAG,prospectively ECG-gated transverse DSCT is a valuable examination to detect and diagnose coronary artery disease with a low dose coronary angiography.The accuracy of the DSCT is approximate to the SCAG.There was no significant difference between the accuracy of two groups.

结果200例患者均成功完成了适应性前瞻性心电门控双源CT冠状动脉血管成像；30例同期行SCAG检查的患者，A组17例：HR≤75 bpm，可评价冠状动脉节段255个，70个冠状动脉节段有105处不同程度的狭窄，95处狭窄程度与金标准SCAG相符，其阳性诊断准确率为90.48%；2种方法的诊断结果得到了较高的一致性(Kappa值=0.853)。B组13例；HR≥91 bpm，可评价冠状动脉节段195个，57个冠状动脉节段有73处不同程度的狭窄，65处狭窄程度与SCAG相符，其阳性诊断准确率为89.04%；2种方法的诊断结果得到了较高的一致性(Kappa值=0.835)。2个心率组间的诊断准确率无明显统计学差异(x~2=0.098，p＞0.05)。30例患者的平均有效辐射剂量为3.67±0.43 mSv结论适应性前瞻性心电门控双源CT冠状动脉成像是一种有效减低辐射剂量的扫描方式，其诊断准确率与金标准SCAG相比得到较高的一致性，且高、低2个心率组间诊断准确率无明显统计学差异。

"冯羽军说,若是因冠心动脉血管阻塞引起心脏肥大,患者服药后仍无好转,就需进行心导管插入术(cardiac catheterization)、冠状动脉造影术(coronary angiography)或心血管成型与扩张手术(Percutaneous Coronary Interventions,PCI).

coronary angiography：冠状动脉造影

侵入性检查方法主要有:1 冠状动脉造影 冠状动脉造影(coronary angiography)能够通过管腔显影,部分显示不稳定斑块的特征,包括斑块的偏心性,斑块破裂留下的溃疡、血栓以及不规则管腔,甚至冠状动脉夹层等.
