盆腹部MSCT扫描数据在髋关节间隙测量中的应用价值

摘要

目的：探讨盆腹部MSCT扫描数据在测量正常髋关节间隙中的再应用价值。方法：对已行盆腹部多层螺旋CT扫描而无髋关节疾患的333例病例，进行薄层骨算法重建、图像MPR后处理，测量股骨头与髋臼前唇连线延长线间距、髋关节前、后间隙并进行统计学分析。结果：薄层重建、MPR处理后的髋关节图像清晰，所测数据满足研究需求。结论：利用盆腹部MSCT扫描数据对正常髋关节间隙的研究，是对MSCT容积数据的一次再利用，无需额外扫描，无辐射产生，既节能、又环保，是一项绿色研究，对髋关节正常值的制定、髋关节疾病的普查和诊断具有较高的应用价值。%Objective:To study the application value of lower abdominal MSCT scan data in measuring normal hip joint space .Meth-ods:Lower abdominal MSCT scan data of 333 cases without hip disease have been reconstructed by bone algorithm and MPR after -treat-ment.The spaces from femoral head to the line between anterior acetabulum labra and normal hip joint spaces were measured with MPR , and the statistical analysis was made .Results:By thin layer reconstruction and MPR after -treatment, the hip joint images are distinct . All the data meet the research needs .Conclusion:It might be a recycling of volume data to study normal hip joint space with lower abdomi -nal MSCT scan data .Extra radiation scan need not carry on , so it was an energy and green study .There were higher values in measuring normal hip joint space and the census and diagnosis of hip joint disease .
