查询词典 CTA

GPC analysesand particle size results indicated that using PFAMA macro-CTA as the first block wasbetter than using the PBMA RAFT agent with respect to the colloidal stability and thenarrow molecular weight distribution of the F-copolymers latices.

改变合成顺序，首先在本体中合成PFAMA大分子链转移剂，然后在细乳液体系中进行BMA的聚合，凝胶渗透色谱和粒径分析表明：可以得到稳定的细乳液和分子量分布窄的含氟嵌段共聚物PFAMA-b-PBMA。

Objective To compare the image results between 64-slice spiral CTA and cardiac multimodality MR scanning in detecting coronary artery disease.

目的 比较64层螺旋CT冠状动脉造影和磁共振心脏多技术扫描对冠心病的诊断结果。

It is found that the low dielectric constant inhibits the disproportion of pyrogallic, but it can be settled by increasing the pH or the water content of the reverse microemulsion to obtain a stable generation of the substrate. Then the activity of SOD is determined in such a system and a bell -shaped curve of the activity vs. W〓 is obtained although only subactivity is found. The reasons can be attributed to the low dielectric constant and the attraction of CTA〓.

的介电常数的降低对邻苯三酚的自氧化有抑制作用，因此实验中通过提高CTAB微乳液的表观pH或增大水化度即W〓，最终得到了一定浓度的底物超氧阴离子O〓〓·，保证了SOD活性的测定，并得到了SOD酶活性随含水量变化的&钟形&曲线。

No significant difference of CBV nor CBF was detected between the stenosed or occluded side and the contralateral side assessed in 20 patients.Conclusion Volume Shuttle CTP provides valuable information on hemodynamic damage and MCA abnormalities in patients with MCA stenosis or occlusion.

结论64排螺旋CT应用容积穿梭扫描模式全脑CTP，为MCA狭窄或闭塞可提供有价值的脑血流动力学信息和全面显示灌注异常范围，并且重建CTA可以显示血管狭窄或闭塞。

The post-processing images were compared with digital substraction angiography and surgery.

将得到的后处理图像与DSA图像和手术结果进行对照，评价CTA诊断脑动脉瘤的应用价值。

Methods Fifteen cases were included in the study, all underwent multi-slice CT and CT portal venography before and after endoscopic variceal ligation. The portal vein and its main bronchi and the twigged veins were depicted and measured.

15例患者在经内镜套扎前、后分别接受门静脉CTA，对门静脉主干、主要属支和侧支循环血管进行显示和测量。

Two same scan protocols were prepared: unenhanced helical and enhanced CTA.

即制定两组扫描参数相同的计划螺旋采集平扫与增强扫描。

Then, the CTA data subtract unenhanced data section-by-section removing bone and brain tissue, just vascular structures remain visible.

然后用增强数据逐层减去平扫数据，自动去除骨与脑组织，只剩下血管影像。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
