目的 研制一款留置针固定装置。方法 留置针固定装置是由底壳和带体组成,通过底壳内对称弹簧柱,其中的垫片用于夹持留置针的接口已起到固定作用。结果 该设计能够对留置针以及安装在该留置针上的正压接头分别进行固定,结构简单,操作使用方便。结论 留置针固定装置可减少管道滑脱及接头的松动,同时能减轻护士工作量,增加美观性,提高患者舒适度。
目的:常规的磁共振序列一般很难准确诊断脑囊虫病.本研究探讨了在3T磁共振上三维快速扰相梯度回波(3D-SPGR)序列和T1-CUBE序列磁共振增强检测脑囊虫病的特点,并对诊断准确性进行了比较.方法:本研究纳入了14名确诊含有33个病灶的脑囊虫病人,对14名病人按0.1mmol/kg注射钆喷酸葡胺(Gd-DTPA)后,用3D-SPGR和T1-CUBE序列采集图像.两名神经放射专家独立评估两个序

目的 探讨颅外弓上动脉损伤的经血管腔内治疗临床应用价值.方法 回顾性总结我院2012.5-2016.5颅外弓上动脉损伤的患者共5例,年龄19-73岁,平均年龄49岁,男4例,女1例.临床症状为颈部及上胸部活动性出血4例,右颈部搏动性肿块进行性增大,彩超提示假性动脉瘤1例.均急诊于我科行经血管腔内诊断及治疗.采用Selding,s方法穿刺股动脉,行主动脉弓、颅外段血管及全脑血管造影显示:右颈外动脉
目的 探讨磁共振3D-FIESTA序列对膝关节韧带的显示效果及临床诊断价值.方法 收集50例临床怀疑膝关节周围韧带损伤的患者,分别对各病例行膝关节常规MR平扫及3D-FIESTA序列扫描,后全部病例经关节镜或手术证实病情.将常规平扫和3D-FIESTA序列扫描结果与关节镜或手术结果对照,对比两种方法显示韧带损伤的敏感性和特异性,并分别测量两种扫描方法脂肪、肌腱的信号强度及背景信号强度标准差,计算
目的 行围术期护理干预。结果57例患者术后,有6例出现发热,10例出现不同程度疼痛,13例出现肝功能异常,无出血和肾功能衰竭并发症,无发生治疗相关性死亡。结论 充分的术前准备,密切的术中配合以及严密的术后护理可提高治疗成功率。
目的 探讨小脑发育不良性节细胞瘤(LDD)的MRI表现特点.方法 对13例经手术病理证实为LDD的MRI表现做回顾性分析.结果 13例LDD均位于小脑半球和蚓部,MRI表现为T1W1上等、低信号条纹结构,T2W1、FLAIR上均可见典型的“虎纹征“表现,增强后病灶出现轻度条状强化.病变具有占位效应,四脑室及脑干示受压改变.7例磁共振波谱NAA轻度减低.结论 LDD具有特征性MRI表现,对术
