Material and Methods:From March,2008 to January,2009,250 patients(146 Males and 104 Females,ranged from 18 to 82 years old,mean age was 48 years old) enrolled in the First Affiliated Hospital of Kunming Medical College were performed dual energy scan(Group A,200 patients) and Neuro-DSA scan(Group B,50 patients) using DSCT.The patients were randomly divided into Group A and Group B.Regarding to the justification of scan protocol,100 patients in Group A were selected as sub-group to explore the scan protocol.The image quality Was analyzed both in four categories(4.0/60、4.5/60、4.0/70、4.5/70) of flow rate and total amount of contrast-enhanced material and in three categories(100—150HU、150—200HU、200-250HU) of CT value of left common carotid artery.The comparison of two scan approach was based on image quality,radiation does, postprocessing methods,time of scanning and subtraction and data storage amount.To validate the diagnostic capability of DE-CTA virtual unenhanced images,100 patients in Group A were undergoing head scan both in routine non-contrast program and DE-CTA virtual unenhanced program.Mean CT values,signal-to-noise ratio,image quality,sensitivity of lesion identification,and radiation does were applied to comparison.According to diagnostic results of dual energy of cerebral arterial angiography,62 patients out of 200 patients in Group A were confirmed with cerebral vessel lesions,the results were complied with DSA findings(the time between the two methods were within 1 week).

材料与方法收集2008年3月到2009年1月间在昆明医学院第一附属医院行DSCT CTA检查者250例(男性146例，女性104例，年龄范围18-82岁，平均48岁)，随机分为A、B两组，A组200例行双能量头颅CTA扫描；B组50例行Neuro-DSA扫描。A组前100例按对比剂不同流率和总量分为4组(4.0/60、4.5/60、4.0/70、4.5/70)对图像质量比较；按触发时左颈总动脉内平均CT位分3组(100—150HU、150—200HU、200-250HU)，比较图像质量的差异；对A、B两组血管图像质量、辐射剂量、后处理的方法、扫描和后处理时间及数据的容量进行比较分析；A组中前100例行常规与DE-CTA虚拟平扫的平均CT值、信号噪声比、图像质量、病灶显示情况、辐射剂量的比较分析；A组中行DSA检查62例(两种方法间隔时间均1周内)，比较两种检查方法诊断结果是否符合，并对其中24例动脉瘤行动脉瘤部位、数目、形态、瘤颈显示程度、瘤颈大小及瘤体长径和短径的比较研究。

The rover was to use its rock abrasion tool Sunday to grind away at a martian outcropping dubbed "Flat Rock," but the tool left "no discernible impression on the rock," NASA's Jet Propulsion Laboratory reported.

After the use niter benzene even treatment and the treatment all around, separately makes the electroencephalogram inspection to two groups of case of illness.results: after the use niter benzene even treatment all around, the treatment group electroencephalogram restores quickly to the comparison group, exceptionally leads obviously to be lower than the comparison group.conclusions: the niter benzene is even is treats the recovery period fluorine acetamide to be poisoned patient's effective method, may enable his/her the brain harm to obtain the as soon as possible repair, improves the brain function, makes the unusual electroencephalogram to restore normal or the change for the better as soon as possible.

在使用硝苯地平治疗前和治疗4周后，分别对两组病例均作脑电图检查。结果：使用硝苯地平治疗4周后，治疗组脑电图恢复快于对照组，异常率明显低于对照组。结论：硝苯地平是治疗恢复期氟乙酰胺中毒患者的有效手段，可使其脑损害得到尽快修复，改善脑功能，使异常的脑电图尽早恢复正常或好转。
