摘要/Abstract

摘要： 目的：探讨骨科金属去伪影（O-MAR）技术在人工关节置换术患者CT检查中去除金属伪影和提高图像质量的效果，阐明该技术对于关节外科临床诊疗工作的意义。方法：收集20例带有人工髋关节和人工膝关节假体患者CT数据。每组数据包括120和140千电子伏特（Kev）2种电子管电压，每个管电压组分别包括非O-MAR组和O-MAR组，每例患者CT数据包括4个小组数据，即120Kev/-O-MAR、120Kev/+O-MAR、140Kev/-O-MAR和140Kev/+O-MAR组。数据收集后使用Mimics软件对数据进行三维重建，对CT数据质量进行定性和定量分析。定性分析包括对伪影严重程度和数据质量评分，定量分析包括对各组金属伪影体积、感兴趣区（ROI）内平均CT值和标准差（SD）的对比。其中ROI 1和ROI2分别选择在射束硬化金属伪影（放射状高密度金属伪影）区域和光子饥饿金属伪影（条带状低密度金属伪影）区域。结果：三维测量，除120Kev/-O-MAR组与140Kev/-O-MAR组间伪影体积比较差异无统计学意义（P=0.062）外，其余各组间伪影体积比较差异均有统计学意义（P<0.05），O-MAR技术明显降低了射束硬化伪影体积。二维测量，除ROI 2中120Kev/-O-MAR组和140Kev/-O-MAR组间平均CT值比较差异无统计学意义（P=0.069）外，其余各组间平均CT值比较差异均有统计学意义（P<0.05），O-MAR技术在二维层面可去除高密度的射束硬化金属伪影和低密度的光子饥饿金属伪影。结论：O-MAR技术可以明显减少人工髋关节和人工膝关节在CT扫描时产生的金属伪影，同时明显提高CT数据的临床价值。

Abstract: Objective: To investigate the metal artifact reduction effect of orthopedic metal artifact reduction (O-MAR) techonology and its improvement effect on the image quality in CT examination in the patients with arthroplasty,and to elaborate the significance of the technology in clinical diagnosis and treatment of arthroplasty.Methods: The CT data of 20 patients with hip or knee prostheses was collected. There were two tube voltages in each group of CT data:120 and 140 Kev. There were also two groups of CT data in each tube voltage group:non-O-MAR group and O-MAR group;there were four subgroups of CT data of each case:120 Kev/-O-MAR, 120 Kev/+O-MAR, 140 Kev/-O-MAR, 140 Kev/+O-MAR. After data collection, Mimics software was applied to conduct three-dimensional(3D) reconstruction for purpose of the qualitative and quantitative analysis of CT data. Qualitative analysis mainly included the grade of severity of metal artifact and quality of data. Quantitative analysis included the volume of metal artifact,the average CT value and standard deviation(SD) in region of interest (ROI). ROI 1 and ROI 2 were chosen at the location of beam hardening artifact (radial high-density metal artifact) and photon starvation artifact (band low-density metal artifact), respectively.Results: According to the result of 3D measurement, the volumes of artifact had no significant difference between 120 Kev/-O-MAR group and 140 Kev/-O-MAR group(P=0.062),but there were siginificant differences in the volumes of artifact between other groups(P<0.05); O-MAR technology decreased the volume of beam-hardening artifact obviously(P<0.05). According to the results of two-dimensional (2D) measurement,there was no significant difference in the average CT values in ROI 2 between 120 Kev/-O-MAR group and 140 Kev/-O-MAR group(P=0.069),but there were significant differences in the average CT values between other groups(P<0.05);O-MAR technology decreased the high-density beam-hardening metal artifact and the low-density photon-starvation metal artifact in 2D measurement.Conclusion: O-MAR technology could significantly reduce the CT metal artifact of hip and knee prostheses and increase the clinical value of CT data.
