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 attachment footprint width on the clavicle and coracoid process of the trapezoid ligament，the distance from attachment footprint center of the trapezoid ligament to the outer edge of the clavicle and coracoid process，and the distance from attachment footprint center of the conoid ligament to the outer edge of the clavicle and coracoid process all showed statistical differences between males and females（all P ＜ 0.05）. There was no correlation between age and various anatomical parameters（all P ＞ 0.05）. Except for the length of the conoid ligament，the anatomical quantitative parameters of the trapezoid ligament and conoid ligament exhibited varying degrees of correlation with the size of the coracoid process（all P ＜ 0.05）. Conclusion：The 3D CS - SPACE sequence clearly displays the anatomical structures of the trapezoid ligament and conoid ligament，and obtains quantitative anatomical parameters of them，providing a basis for individualized surgical treatment of patients with acromioclavicular joint injuries and reducing the occurrence of complications.
