Objective To explore differential diagnosis of hepatic nodules from benign and malignant lesions by DSCT perfusion.Methods 20 patients without hepatic diseases and 49 hepatic nodules confirmed by pathology,including 11 HCC, 15 hepatic cavernous hemangioma and 23 metastatic tumors.CT scanning was started at 8sec and at 64 sec (delayed phase) of the whole liver after intravenous administration by DSCT.The raw data were analyzed to obtain time-density curve and other parameters for HBF, HBV, MTT, HAF and PS Base.Results The differences of HBF, HBV, MTT, HAF, PS Base among 4 groups were statistically significant.Compared with normal liver, HBV and HAF in HCC and hemangioma increased significantly.HBF in HCC increased significantly.HBF and HAF in the solid portion were significantly higher in HCC group more than that of HM and HA groups.HBV were significantly higher in HCC and HA groups than that of HM group.MTT was significantly lower in HCC group than that of HM and HA groups.HBF were significantly higher in adjacent parachyma and HAF were significantly lower in HCC and HM groups than that of HA group.PS was significantly higher in HM group than that of HA group.MTT was significantly decreased and HAF was significantly increased in HCC group compared with HM and HA.Conclusion Mutiple perfusion parameters were very useful for differential diagnosis of hepatic nodules from benign and malignant lesion by DSCT.

目的 通过对我市某三级医院合理用血情况的调查，评价医院输血科在促进合理用血工作中所起的作用。 方法 调查2010年以来业务发展与血液制品使用情况；调查2011年以来不合理输血发生情况；了解医院围绕促进合理用血所做的工作，特别是输血科建设在促进合理用血方面的作用。
目的 医院(HIS)、输血科和血站信息系统联网应用，对整个医院的输血管理、工作效率、质量管理等环节发挥重要作用。方法 根据现代医院管理及现阶段医院等级评审要求，医院输血管理得到越来越多的重视，医院输血信息管理是三个信息系统；一是医院管理信息系统(HIS系统)，二是输血科信息系统，三是供血机构血站信息系统。
杀伤细胞免疫球蛋白样受体(KIR)是一种主要表达于NK细胞和部分T细胞表面的识别HLA配体的受体。研究发现KIR在慢性炎症、持续病毒感染情况下，发挥着重要作用，本文就KIR的结构多态性、与配体的识别以及探讨KIR在病毒性肝炎发病及转归中的作用的研究进展进行综述。
目的 探讨球囊阻断术阻断腹主动脉在凶险型前置胎盘剖宫术中的应用。方法 收集2014年10月至今4例凶险型前置胎盘剖宫术应用球囊阻断底位腹主动脉,统计术前用血申请及术中、术后病人实际用血情况,观察采用阻断术中及术后病人出血情况。结果 球囊阻断术在4例剖宫产术的用血均比术前申请用量少,仅一例病人在松开球囊时发现有少量渗血,行子宫动脉结扎术后没有明显出血,4例患者全部保全子宫、母婴平安康复出院。结论 球
针对腹部低剂量多层探头计算机X射线断层扫描技术(MDCT)图像虽然可以降低患者细胞癌变的风险,但是同时也降低图像的诊断质量及扩散性滤波参数凭经验设计的问题,本文应用客观设置参数的3D非线性扩散性均值滤波器改善腹部低剂量MDCT图像质量.首先根据非线性扩散性滤波器的原理推导出扩散值与体素梯度的依赖关系.然后根据改依赖关系,抽取空气区域噪声取得均值设置扩散性参数.实验验结果表明本文设计的滤波器能有效改
目的:探讨四肢关节专用MRI对剥脱性骨软骨炎(OCD)的诊断价值.方法:回顾性分析52例经关节镜或手术病理证实为剥脱性骨软骨炎患者的X线平片和MRI影像资料.结果:OCD MRI表现为关节承重部位软骨下骨质不同程度缺损,依据损害的范围和形状、部位、软骨和软骨下骨的情况,碎片下方的高信号区域和是否存在游离体,将OCD MRI表现分为V型:Ⅰ型6例,Ⅱ型13例,Ⅲ型20例,Ⅳ型9例,Ⅴ型4例.结论:O
目的:探讨黏液样脂肪肉瘤(myxoid liposarcoma,MLS)的影像学特点及误诊原因、防范措施.方法:回顾性分析我院收治的长期误诊为血管瘤的MLS1例的临床资料,并复习相关文献.结果:患者因右腕桡侧肿物25年余入我院手足外科.曾在当地卫生院诊断为血管瘤行手术切除治疗,术后6个月复发.近2年肿物增长加快,为求进一步诊治就诊我院.入我院后经超声、X线及MRI检查等仍诊断右腕部血管瘤,遂行肿瘤
目的:探讨MRI表观弥散系数值(apparent diffusion coefficient,ADC)在腰椎间盘退变中的价值.方法:对50例腰痛患者进行腰椎MRI常规序列和弥散加权成像(diffusion weighted imaging,DWI)扫描,测量每个腰椎间盘平均ADC值,分析腰椎间盘平均ADC值与退变分级、解剖部位的相关性.结果:不同退变级别腰椎间盘平均ADC值有统计学差异(P＜0.0
目的:评价多层螺旋CT扫描技术对椎弓崩裂性滑脱的诊断价值.方法:对53例腰椎滑脱并椎弓崩裂的多层螺旋CT表现进行回顾性分析.结果:腰椎椎弓峡部崩裂多层螺旋CT表现均可见椎弓宽窄不一的低密度裂隙,边缘不规则,椎管骨性面表现环状骨质不连续,椎管横径变小,前后径变长.结论:应用多层螺旋CT诊断椎弓崩裂性滑脱可大大提高诊断的准确性和及时性,为正确治疗腰椎滑脱提供了有力依据.
