Purpose In patients with renal dysfunction,computed tomographic pulmonary angiography(CTPA)may lead to contrast-induced nephropathy.The development of unenhanced MR angiography(SLEEK MRA)has great clinical significance for imaging pulmonary arteries in patients with renal dysfunction or who cant use contrast agent for other reasons.Our objective was to evaluate relative detection of pulmonary embolism(PE)with unenhanced MR angiography by applying spatial labeling with multiple inversion pulses sequence(SLEEK)imaging for patients with mild or moderate renal dysfunction.

目的：人工关节置换术后翻修手术(Revision of Total Joint Replacement,RTJR),正随着初次人工关节置换(Primary Total JointReplacement,PTJR)病例的上升而逐年上升,约占全部关节置换病例10％,这将是全球关节外科医生和所有接受关节置换患者都必须面对的严峻挑战。感染,至少目前在中国,仍然是人工关节置换术后翻修的主要原因之一。在缺乏完
传统的手法复位方法由计算机控制器械手臂系统代替是集多项现代高科技手段于一体的综合体。骨科医生可以远离手术台操纵机器进行复位，完全不同于传统的复位概念，在世界创伤外科领域是当之无愧的革命性骨折复位工具。骨科医生只需坐在通常是手术室的控制台上，观测和指导机械臂工作就可以。
目的 对比三种不同剂量对比增强磁共振颈部血管成像质量,探讨低对比剂剂量颈部血管磁共振成像可行性及临床应用价值.方法：收集临床拟行磁共振颈部血管成像患者100例,随机分成三组(A组 n=30,B组 n=30,C组 n=30).所有患者均在3.0T磁共振上采用一致的成像序列行对比增强颈部血管成像(CE-MRA).A、B、C三组对比剂剂量分别为0.2mmol/kg、0.075mmol/kg,0.05mm
