简介：据HamonM[Radidogy，2007，245（3）：720-731]报道，通过Mete分析发现，在诊断冠心病时64排螺旋CT比16排螺旋CT更出色。多排螺旋CT（multidetector-rowspiralCT，MDCT）指组成CT的探测器排数，排数越多，图像分辨率越高,扫描时间越短。

简介：目的探讨Moyamoya病的多层螺旋CT血管成像（CTA）临床应用价值。方法30例Moyamoya病病人,其中男性18例，女性12例，年龄14～62岁，平均年龄42．60岁。发病高峰中30～40年龄段为12例，40～50年龄段10例。做16层螺旋CTA，扫描参数为：250kV，250mA，螺距15，扫描层厚1mm。同时6例又行DSA检查，将其CTA结果与DSA图像进行比较。结果30例中病变累及颈内动脉者共27例，占总例数的90．0％，受累段均为颈内动脉末段。病变累及双侧者26例（占总例数86．7％）。30例CTA均清晰显示发生狭窄、闭塞的颈内动脉远端、大脑前中动脉近端及迂曲扩张的大脑后动脉、后交通动脉等代偿动脉，狭窄血管显示率100％；清晰显示脑底异常血管网者28例，异常血管网显示率93.3％。30例中有6例同时行DSA检查，两者检查结果完全一致。结论CTA可以清楚显示Moyamoya病脑血管改变特点，包括颅内血管狭窄及脑底异常血管网，可以考虑作为Moyamoya病诊断的重要影像学筛查方法之一。

简介：目的评估急诊闭合复位股骨近端抗旋髓内钉(proximalfemoralnailantirotationblade,PFNA)治疗青壮年股骨粗隆下骨折的临床疗效。方法对2008年6月~2012年6月经急诊手术治疗的16例青壮年粗隆下骨折进行回顾性分析,男11例,女5例;年龄32~45岁,平均36.2岁。按Seinsheimer分型:ⅡB型2例,ⅡC型1例,ⅢA型6例,ⅢB型1例,Ⅳ型4例,Ⅴ型2例。所有患者急诊手术前均进行美国麻醉学会(ASA)评分,术后对手术时间、术中出血量、完全负重时间和骨折愈合时间进行评估。末次随访采用Parker-Palmer评分标准评估患者术后活动能力。结果本组均获得随访,随访时间为6~28个月,平均13个月。本组患者评分平均为(7.72±1.40)分。结论急诊闭合复位PFNA内固定是治疗青壮年股骨粗隆下骨折的可靠方法,能提供坚强的固定,允许术后早期功能锻炼。
