Methods Twenty four patients with chronic renal diseases and 48 healthy volunteers were examined with SS-EPI DWI at 3.0T MR. In chronic renal disease group, RIF of 14 patients who received renal biopsy was determined as grade Ⅰ and Ⅱ based on the tubule- interstitial damage degree, while RIF of 10 patients with uremia, who did not receive biopsy but had nephrogenic renal atrophy, was categorized as grade Ⅲ.

对照组（48例正常志愿者）和慢性肾病组（24例慢性肾脏疾病患者）在肾脏常规MR扫描后行DWI扫描，慢性肾病组14例行穿刺活检，根据病理结果将肾小管间质损害程度分为Ⅰ、Ⅱ级；另10例肾脏体积缩小的慢性肾功能衰竭尿毒症期患者定为Ⅲ级。

Methods 24 patients known to suspect of having pulmonary embolism underwent MCTPA with 20 ml contrast medium. Scanning delay time was adjusted by using a test bolos. Contrast medium injection rate was 5.5 ml/s. The time of imaging data acquisition was 2-3 s. In addition 24 patients undergoing MSCTPA with 50 ml contrast medium were included in control group. Imaging quality was evaluated by five degree with blind method.

应用多层螺旋CT对24名疑似肺栓塞的病人行CTPA检查，对比剂总量为20 ml(300 mgI/ml)，以单层动态增强扫描所测时间－密度曲线的峰值时间为扫描延迟时间，对比剂注射速率5.5 ml/s，数据采集时间2~3 s；另随机选择24例常规对比剂剂量(50 ml) CTPA检查影像作为对照组，影像质量按5级行盲法评价。

Free-running frequencies of the oscillators are set slightly below the horizontal and vertical pulse rates, and the stripped pulses are used to trigger the oscillators prematurely and thus to synchronize them to the line and half-frame rates half-frame because United States television interlaces the

将振荡器的自由振荡频率设置得略低于水平和垂直脉冲频率，剥离出来的脉冲用于提前触发振荡器从而使振荡器与行频和半帧频同步（由于美国电视在交替的垂直扫描时进行隔行扫描，所以是半帧频）。

In 1242 cases of NPC,358 cases were cranial perineural invasion by imaging diagnosis,the occurrence rate was 28.8 percent;116 cases of whom appeared cranial nerve palsies,the occurrence rate was 9.34 percent.307 cases were underwent MRI and CT examinations,90 cases were cranial perineural invasion by imaging diagnosis, the occurrence rate was 29.32 percent;30 cases of whom appeared cranial nerve palsies, the occurrence rate was 9.77 percent.

1.1242例行MRI扫描病例中，影像诊断鼻咽癌沿颅神经周围浸润者358例，发生率为28.8％；其中出现颅神经症状和体征者116例，发生率为9.34％。同时行MRI和CT扫描的307例病例中，经影像诊断为鼻咽癌沿颅神经周围浸润者90例；发生率为29.32％；其中出现颅神经麻痹的为30例，发生率为9.77％。

Methods MSCs were cultured with inbred line small-ear cancellous bone of Ban Na pigs . A 1.5 centimeter segmental defect was created in the mid-upper part of the radial shaft of adult rabbit. The defects were implanted into composited xenogeneic bone in experimental group and xenogeneic bone alone in control group , the defects were not filled with anything in blank group . The repair capability of the defects was assessed by scan electron microscope before operation and physical , histology, X-ray , transmission electron microscope, SPECT and bone mineral density examinations 4 , 8 and 12 weeks after operation .

将MSCs与版纳近交系小耳猪松质骨在体外联合培养，兔桡骨中上段制成1.5cm的骨—骨膜缺损模型，实验组植入复合异种骨，对照组植入单纯异种骨，空白对照组不植入任何材料，分别于术前行标本的扫描电镜观察和术后4周，8周，12周各时间点行标本的大体观察，组织学观察，X线片观察，透射电镜观察，SPECT扫描及骨密度测试，比较其骨缺损区骨修复愈合情况。

Methods Thirty volun teers underwent the low-dose MSCTwithout administration of intravenous contrast material.The scan parameters were120kVP,16～20mAs,slice thickness5～7mm,slice increment1mm,feed/rotatio7mm.

对30例无症状的受试者行肺部低剂量多层螺旋CT扫描，扫描参数为：120kVP、16～20mAs，层厚5～7mm，层距1mm，螺距为7mm/转。

Methods: The clinical and MRI findins of 21 cases (benign 10 case and malignant 11 cases) of GTN which proved by pathology were retros pectively reviewed, all the patients underwent MR scaning, 16 of 21 cases underwent dynamic contrast-enhanced MR scaning.

回顾性分析21例（10例良性、11例恶性）经病理证实的GTN临床和MRI资料，所有病例均行MR常规扫描，其中16例行MR动态增强扫描。

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。
