［摘 要］ 目的：使用三维可变翻转角快速自旋回波（three⁃dimensional sampling perfection with application optimized contrast
using different flip angle evolution，3D⁃SPACE）序列联合压缩感知（compressed sensing，CS）技术，在健康人群中定量测量喙锁韧
带的两个组成部分，斜方韧带与锥状韧带各自的长度、附着点宽度、附着点位置等解剖学参数。方法：收集无肩部外伤行肩关
节磁共振（magnetic resonance imaging，MRI）检查的志愿者64例，进行冠状位T1加权像（T1⁃weighted image，T1WI）3D CS⁃SPACE
序列的扫描。两名放射科医师分别对图像进行多平面重建，在斜冠状位图像上测量斜方韧带与锥状韧带的长度、锁骨上附着
处宽度以及附着处中心点距锁骨外侧缘的距离，在斜矢状位图像上测量两者在喙突上附着处宽度，在斜轴位图像上测量斜方
韧带与锥状韧带在喙突附着处中心点距喙突外侧缘的距离以及喙突的大小。当两名医师测量结果具有一致性时，取平均值用
于统计学分析。按性别分组，比较各参数组间一致性，并将喙锁韧带各解剖定量数据与年龄、喙突大小进行相关性分析。结
果：斜方韧带长度、在锁骨及喙突上的附着处宽度、附着处中心点距锁骨、喙突外侧缘的距离以及锥状韧带附着处中心点距锁
骨、喙突外侧缘的距离在男女组间的差异均有统计学意义（P均< 0.05）。年龄与各解剖参数间均不具有相关性（P均> 0.05）。
除锥状韧带长度外，其余斜方韧带及锥状韧带解剖学定量参数均与喙突大小具有不同程度的相关性（P 均< 0.05）。结论：
3D CS⁃SPACE序列能够清晰显示斜方韧带与锥状韧带的解剖学结构，通过其获得斜方韧带与锥状韧带的定量解剖学参数，为
肩锁关节损伤患者的个体化手术治疗提供依据，有利于减少并发症。

［Abstract］ Objective：Using the three⁃dimensional sampling perfection with application optimized contrast using different flip angle
evolution（3D ⁃ SPACE）sequence combined with compressed sensing（CS）technology，the anatomical parameters of the trapezoid
ligament and the conoid ligament（the two components of the coracoclavicular ligament），such as the length，the attachment footprint
width，and the position of attachment footprint center，were quantitatively measured in a healthy population. Methods：Sixty ⁃ four
volunteers without shoulder trauma who underwent shoulder joint magnetic resonance imaging（MRI）examination were enrolled. The
coronal T1⁃weighted image（T1WI）3D CS⁃SPACE sequence scans were performed on them. Two radiologists performed multiplanar
reconstruction on these images，measuring the length of the trapezoid and conoid ligaments，the attachment footprint width on the
clavicle，and the distance from the attachment footprint center to the outer edge of the clavicle on the oblique coronal image. The
attachment footprint width on the coracoid process was measured on the oblique sagittal image. The distance from the attachment
footprint center of these two ligaments to the outer edge of the coracoid process and the size of the coracoid process were measured on
the oblique axial image. When the measurement results of two physicians were consistent，the average was taken for statistical analysis.
Volunteers were grouped by sex，the consistency of each parameter was compared，and the correlation between anatomical quantitative
data of the coracoclavicular ligament and age or coracoid process size was analyzed. Results：The length of the trapezoid ligament，the
