To compare the image quality of the three sequences in two groups by One-Way ANOVA and T Test. The qualitative assessment standards include clarity, artifacts, signal uniformity, the conspicuity of enhanced vein and the observable grade of intrahepatic venous branchs. The quantitative assessment standards include SNR and CNR of intrahepatic portal vein and hepatic veins. Furthermore, the anatomy and variations of the intrahepatic portal vein and hepatic veins are statistical analysed.

通过方差分析和T检验分别对A、B组三个序列的图像质量进行比较，评定标准包括清晰度、伪影、信号均匀性、静脉强化程度及肝内静脉分支显示级数等定性指标和肝内门静脉、肝静脉的SNR(Signal-Noise Ratio，信噪比)及CNR(Contrast-Noise Ratio，对比度噪声比)等定量指标。

目的 探讨脑内动静脉畸形CT、MRI、CTA、MRA、DSA等影像学诊断及其与病理学表现的相关性方法本文收集颅内动静脉畸形54例，其中脑动静脉畸形45例，脑膜动静脉畸形1例，硬脑膜动静脉畸形1例，硬脑膜动静脉瘘7例，并经过CT、MRI、CTA、MRA、DSA及手术明确诊断。

Results In the group of 67 cases treated with high ligation by laparoscopy,the scrotum discomfort of left scrotum was lightened obviously after operation of 2～4 days in 60 cases,the expanding varicosity vein disappeared or was postponed obviously.In the last cases,5 cases had obvious improvement after operation of 10 days and 2 cases felt light scrotum discomfort after operation of 3 months.

结果 腹腔镜下高位结扎精索静脉组67例中，60例术后2～4天内左侧阴囊坠痛感明显改善，阴囊内曲张的精索静脉明显减缓或消失，5例在术后10天内上述症状明显改善，2例患者上述症状轻度改善，术后随访3个月左侧阴囊仍有轻度坠痛感；本组中有22例不育症患者在术后复查精液常规，精子数及活动率均明显改善。

In the group of 115 cases treated with high ligation by retroperitoneal approach,the scrotum discomfort of left scrotum was lightened obviously after operation of 2～4 days in 67 cases,the expanding varicosity vein disappeared or was postponed obviously.

结果 腹腔镜下高位结扎精索静脉组67例中，60例术后2～4天内左侧阴囊坠痛感明显改善，阴囊内曲张的精索静脉明显减缓或消失，5例在术后10天内上述症状明显改善，2例患者上述症状轻度改善，术后随访3个月左侧阴囊仍有轻度坠痛感；本组中有22例不育症患者在术后复查精液常规，精子数及活动率均明显改善。

DSA features included: dilatations of brain venule could be seen and the number of brain veins increased; the circulati...

其DSA影像学主要表现为：全脑小静脉扩张、迂曲、数目明显增多；全脑动静脉循环时间延长；丘纹静脉和大脑内静脉系统显影增粗、扩张，并发生深静脉滞流，呈现出"雪花样"表现；静脉窦内对比剂滞留、显影延迟或残缺不全。结论：DSA全脑血管造影是诊断脑静脉系统血栓的可靠方法。

Of the top of the superior aortic recess extended to the level of the aortic arch from which the branchiocephalic trunk arises. At the level of the aortic arch, 100%of the lymph nodes of superior vena cava were located among the aortic arch, superior vena cava and trachea. At the level of azygos vein, 100%of the lymph nodes of azygos vein and the superior aortic recess were located among the superior vena cava, arch of azygos vein, trachea and concavity of aortic arch.

主动脉弓和奇静脉弓在同一横平面占20.00%±7.30%，40.00%±8.94%的奇静脉弓在主动脉弓凹面平面；②80.00%±7.30%的主动脉上隐窝上界位于主动脉弓右前端头臂干起始处；③在主动脉弓平面，腔静脉后淋巴结位于主动脉弓、上腔静脉和气管之间，出现率为100%；④在奇静脉弓平面，奇静脉弓淋巴结和主动脉上隐窝位于上腔静脉、奇静脉弓、气管和主动脉凹面所围成的气管前间隙内。

In the early stages, the intrapulmonary eins are connected to the eins of the systemic circulation.

在发育早期，肺内静脉与体循环静脉相连，而到了晚期，肺内静脉与起源于心房的原始肺静脉相连。

On the way down, it gies off some branches, such as the pericardiophrenic branch and the anterior intercostal arteries, and it is cloaked by enae comitanes, which drain to the respectie brachiocephalic ein ia the internal thoracic ein.9

在下降途中，它发出一些分支如心包膈动脉、肋间前动脉，并被伴行静脉覆盖，这些静脉通过胸廓内静脉引流至相应的头臂静脉。

It is OK that radiography of phallic sponge body checks indication blood free land leaks by phallic sponge body to glans, still can be in at the same time inside vein of prostate vein clump, pudenda and double Qia inside vein system see radiography agent develop, making clear vein leak is serious, belong to complexity vein leakage.

阴茎海绵体造影检查显示血液可以自由地由阴茎海绵体漏向龟头，同时还可在前列腺静脉丛、阴部静脉和双髂内静脉系统内见到造影剂显影，表明静脉泄漏是严重的，属于复杂性静脉漏。

After pericardial effusion,the diastolic pressure of right ventricle and pulmonary vein pres-sure pulsated with intrathoracic pressure;the pressure of carotid vein and femoral vein were still stable.

颈内静脉及股静脉压较稳定，波动幅度较小，分别为0.06kPa和-0.06kPa；心包填塞后，胸内压呼吸性波动加大，左右心室舒张压、肺静脉压的波动幅度随之加大，但颈静脉压及股静脉压仍较稳定。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
