摘要：


文题释义：

股骨髋臼撞击综合征：由于股骨头以及髋臼的解剖异常导致二者在髋关节运动中产生异常接触，特别是在髋关节屈曲和旋转时，会出现软骨和盂唇损伤以及髋关节疼痛，可通过X射线片、CT、MRI等影像学检查进行量化评估，量化指标包括EE角、α角、LCE角。
MRI三维成像：MRI通常用于扫描具有高图像质量的软组织，非常适合使用质子(1H)核作为信号源的软组织扫描，其数据本身即是一个三维图像，在诊断轻微损伤，尤其是扭伤和部分撕裂方面较二维MRI更可靠。

背景：MRI作为股骨髋臼撞击综合征的主要影像学检查方法，可清晰呈现髋关节软组织的结构，借助三维可视化技术可用MRI进行骨组织三维成像，目前缺少有关髋关节MRI三维成像对股骨髋臼撞击综合征量化评估的研究报道。
目的：对股骨髋臼撞击综合征患者的MRI图像进行三维成像，并基于三维图像测量EE角与α角，量化评估骨结构变化。
方法：选取24例明确诊断为股骨髋臼撞击综合征患者，男12例，女12例；年龄36-53岁，平均43.47岁，身高158-190 cm，平均
172.46 cm；体质量62-87 kg，平均77.79 kg，采用GE Discovery MR 750，3.0T磁共振成像系统进行髋关节成像扫描，患者仰卧位，轴向三维梯度回波，厚度：0.6 mm，X / Y分辨率：0.365 mm/0.365 mm。将原始T2矢状位.dicom格式数据导入Materialise Mimics Innovation Suite 16.0 软件，采用半自动分割方式重建，将碰撞区域可视化并进行分析。

结果与结论：①使用MRI图像三维重建能够精确测量α角为(62.86±6.36)°，EE角为(13.68±3.42)°，髋关节MRI三维图像所得α角能有效反映股骨髋臼撞击综合征；②髋关节MRI三维图像能立体显示髋关节软骨和骨骼的形态，为治疗方案的选择提供参考，具有发展和应用前景。

Abstract: BACKGROUND: As the main imaging method of femoroacetabular impingement syndrome, MRI can clearly show the structure of hip joint soft tissue. With the help of three-dimensional visualization technology, MRI can be used for three-dimensional imaging of bone tissue. There is currently no report on quantitative evaluation of femoroacetabular impingement syndrome using three-dimensional hip MRI.  
OBJECTIVE: Three-dimensional imaging was performed on MRI images of patients with femoroacetabular impingement syndrome, and EE angle and α angle were measured based on three-dimensional images to quantitatively evaluate bone structure changes.
METHODS: Totally 24 cases of femoroacetabular impingement syndrome were selected. They were 12 males and 12 females, aged from 36 to 53 years (average, 43.47 years); height from 158 to 190 cm (average, 172.46 cm); weight from 62 to 87 kg (average, 77.79 kg). Each MRI was completed on a GE Discovery MR 750, 3.0T system with the patients in the supine position. An axial three-dimensional gradient-echo was performed. Thickness: 0.6 mm, X/Y resolution: 0.365 mm/0.365 mm. Raw T2 sagittal data in .dicom format were input into Materialise Mimics Innovation Suite 16.0 software. Semi-automatic segmentation method was adopted to visualize and analyze the collision area.  
RESULTS AND CONCLUSION: (1) The α angle (62.86±6.36)° and EE angle (13.68±3.42)° could be accurately measured by three-dimensional reconstruction of MRI images. The α angle obtained from three-dimensional MRI images of hip joint could effectively reflect femoroacetabular impingement syndrome. (2) The three-dimensional image of hip MRI stereoscopically displays the morphology of hip cartilage and bone, provides a reference for the choice of treatment options, and has development and application prospects.

Key words: magnetic resonance imaging, femoroacetabular impingement, visualization, EE angle, α angle, three-dimensional imaging
