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。

Two months after a reading invention program based on auditory training, the dyslexic children received another imaging scan using the same tasks. The results showed that the bilateral brain activation of the dyslexic children was significantly higher than the pre-training, especially in the cingulate gyrus (BA23) of bilateral frontal lobe, the bilateral supramarginal gyrus (BA40), the left precuneus (BA7), the right temporal-parietal region (BA22 and BA48) and the right middle frontal gyrus(BA8), suggesting that the activation pattern of the dyslexia for phonological processing gradually changed to that of the normal ones.

As same as the above-mentioned reason, because theconditions at the inside straight boundary of the binarycomposite material can not be easily satisfied, here, anelastic circular inclusion with large radius is used to replacethe upper half space of the binary composite material, so the〓mary binary composite mater ial problem can be changed〓the scattering problem of a circular elastic inclusion andto the scattering problem of a circular eastic inclusion and〓circular cavity in an infinite space to the steady incident〓wave.
与前面两个问题的理由一样,同样,由于问题中双质复合材料的内部直边界上的边界条件不易解析满足,为此,本文采用了一个半径很大的弹性实夹杂来代替问题中双质复合材料的上半空间部分,而将原来的双质复合材料问题转化成了无限大空间中一圆形弹性夹杂和一圆孔对稳态P波的共同散射问题,根据该问题的特点写出了弹性夹杂内外波场中波函数的一般形式解,利用该问题中夹杂和圆孔处的位移和应力的连续条件,并采用复数傅立叶级数展开技术将其化为一个仅包含问题波函数中未知系数的无穷线性代数方程组,在满足一定计算精度的前提下,通过有限项截断进行近似求解,进而讨论了双质复合材料中圆孔边界处的动应力集中系数随不同入射角、圆孔的不同位置、以及入射波的不同无量纲波数的变化和分布情况。
