摘要：


文题释义：
实影渲染：该技术是通过模拟光线在虚拟场景中的传播、反射、折射、阴影等物理行为，利用计算机算法和图形处理能力，将三维模型转化为具有逼真光影效果的二维图像，让重建出来的图像更为逼真，更具立体感，能显示更多的毗邻细节。
多平面重建技术：是一种基于CT获取的原始横断面图像数据进行后处理运算的医学影像技术。其核心原理是利用扫描获得的、由体素(Voxel)组成的三维容积数据，通过计算机软件算法，按照操作者指定的任意平面方向重新进行图像切片和重组。


摘要
背景：髋关节的解剖结构复杂，通过参数指标量化评估困难，实影渲染技术对于髋关节细微结构精准显示及疾病检出具有重要帮助。
目的：通过CT多平面重建技术及实影渲染技术三维数字化测量评估髋关节解剖形态参数指标，并进行差异性比较和相关性分析，为髋关节相关疾病的诊断评估及髋关节置换提供精准解剖参数依据。
方法：纳入年龄≥18岁、无髋关节创伤及疾病受试者的髋关节螺旋 CT 资料 156 例(312侧)，按10岁一个年龄段，分为6组。对CT图像进行实影渲染和多平面重建技术处理，测量双侧髋关节髋臼外展角、股骨头中心距离、髋臼覆盖率、髋臼深度、颈干角、股骨偏心距、中心边缘角、髋臼前断面角、髋臼后断面角、髋臼前倾角。运用SPSS统计软件比较不同年龄段双侧髋关节解剖参数的差异，分析不同解剖指标之间以及与临床基线资料的相关性。
结果与结论：①髋关节解剖参数指标按左右侧比较，两侧颈干角、股骨偏心距差异有显著性意义(P < 0.05)；②按性别比较，髋臼外展角、股骨偏心距、髋臼前倾角女性大于男性(P < 0.05)；③按不同年龄段分组比较，青年组在髋臼最大深度、髋臼覆盖率、髋臼前断面角、髋臼后断面角、中心边缘角小于老年组(P < 0.05)；④髋臼覆盖率传统法与革新法、髋臼最大深度冠状位与横轴位比较，差异无显著性意义，但存在显著相关性(r=0.76，0.95，P < 0.01)；髋臼外展角与体质量指数、髋臼覆盖率、髋臼最大深度、中心边缘角、髋臼前断面角、髋臼后断面角呈负相关(P < 0.05)，且后5个指标彼此之间存在正相关(P < 0.01)；⑤提示实影渲染及多平面重建技术有利于髋关节解剖参数指标的精准测量和评估，不同性别、不同年龄段受试者的参数指标存在明显差异，并呈现一定特征趋势，且不同解剖参数指标之间存在显著相关性。

Abstract: BACKGROUND: The complexity of hip joint anatomy makes it difficult to quantitatively assess by parameter indexes, and real-image rendering technology is important for the accurate display of hip joint microstructure and detection of diseases.
OBJECTIVE: To evaluate the anatomical and morphological parameters of the hip joint through three-dimensional digital measurement by CT multi-planar reconstruction and cinematic rendering, compare the differences and analyze the correlation, so as to provide a precise anatomical parameter basis for the diagnosis and evaluation of hip-related diseases and hip arthroplasty.
METHODS: Spiral CT images of the hip joints of 156 subjects (312 sides) aged 18 years or older without hip trauma or disease were collected and divided into six groups, each 10 years old. The CT images were processed with cinematic rendering and multi-planar reconstruction. Sharp angle, femoral head distance, acetabular coverage, acetabular depth, Cape verde, femoral offset, center edge angle, acetabular anterior section angle, posterior acetabular section angle, and acetabular anteversion were measured bilaterally. SPSS statistical software was used to compare the differences in anatomical parameters of bilateral hip joints in different age groups, and to analyze the correlation between different anatomical indexes and clinical baseline data. 
RESULTS AND CONCLUSION: (1) Comparison of the anatomical parameters of the hip joint by left and right sides exhibited that the difference between Cape verde and femoral offset was statistically significant (P < 0.05). (2) Compared by gender, the sharp angle, femoral offset, femoral head distance and anterior acetabular tilt were greater in women than in men (P < 0.05). (3) Compared by different age groups, the values of the young group in the indexes of acetabular depth, acetabular coverage, acetabular anterior section angle, posterior acetabular section angle, anterior acetabular tilt, and center edge angle were smaller than those of the old group (P < 0.05). (4) When acetabular coverage-traditional method was compared with acetabular coverage-innovative method and acetabular depth-coronal with acetabular depth-axial position, the differences were not statistically significant, but there was a significant correlation (r=0.76, 0.95, P < 0.01). Sharp angle was negatively correlated with body mass index, acetabular coverage, acetabular depth, center edge angle, acetabular anterior section angle, and posterior acetabular section angle (P < 0.05), and acetabular coverage, acetabular depth, center edge angle, acetabular anterior section angle, and posterior acetabular section angle were positively correlated with each other (P < 0.01). (5) It is indicated that cinematic rendering and multi-planar reconstruction technology facilitates accurate measurement and assessment of hip joint anatomical parameter indexes, and there are obvious differences in parameter indexes between different genders and age groups, with certain characteristic trends, and there are significant correlations between different anatomical parameter indexes.
