［摘 要］ 目的：探讨三维可变翻转角快速自旋回波（sampling perfection with application optimized contrast using different flip
angle evolution，SPACE）序列联合压缩感知（compressed sensing，CS）技术在肩锁关节损伤诊断中的应用价值。方法：前瞻性地
纳入2023年5月—2024年2月在南京医科大学第一附属医院就诊的有肩部外伤史、临床怀疑肩锁关节损伤的患者34例，对患
者分别进行常规二维（two⁃dimension，2D）磁共振序列和基于CS的3D CS⁃SPACE序列扫描。分别在两组图像上测量肱二头肌
长头腱和肱骨骨髓腔的信号强度和标准差，并计算出信噪比（signal to noise ratio，SNR）、对比噪声比（contrast to noise ratio，
CNR）；3位医生分别通过两组图像评估肩锁关节的损伤情况并给出其诊断信心评级。比较两组图像骨髓腔、肱二头肌长头腱
的SNR、CNR以及诊断信心评级；分别分析3位医生在常规2D图像中的诊断一致性和3D CS⁃SPACE图像中的诊断一致性，最
后评估两组图像之间的诊断一致性。结果：图像质量的客观评价中，3D CS⁃SPACE图像的SNR和CNR均明显优于常规2D图
像；两组图像诊断信心的评级，2位医生的3D CS⁃SPACE图像评级明显高于常规2D图像，1位医生评级差异无统计学意义；3位
医生在常规2D图像和3D CS⁃SPACE图像上对肩锁关节损伤的评估均具有较高的一致性（κ均>0.6），两组图像对肩锁关节的损
伤评估具有较高的一致性（κ均>0.6）。结论：对于肩锁关节损伤的诊断，3D CS⁃SPACE图像与常规2D图像具有较高的一致性，
且3D CS⁃SPACE序列能够在缩短扫描时间的同时获得更好的图像质量。

［Abstract］ Objective： To assess the value of sampling perfection with application optimized contrast using different flip angle
evolution（SPACE）sequence combined with compressed sensing（CS）technique in the diagnosis of acromioclavicular joint injury.
Methods：Total 34 patients with a history of shoulder trauma and suspected acromioclavicular joint injury in the First Affiliated
Hospital of Nanjing Medical University were prospectively included form May，2023 to February，2024. Conventional 2D magnetic
resonance sequence and 3D CS⁃SPACE sequence scanning based on CS were performed on the patients. Signal intensity and standard
deviation of long head tendon of biceps and bone marrow cavity of humerus were measured on two sets of images，and SNR and CNR
were calculated. Three doctors assessed the injuries of the acromioclavicular joint through two sets of images and gave their diagnostic
confidence rating. The SNR，CNR of bone marrow cavity and biceps long tendon，and diagnostic confidence ratings were compared
between the two groups. The diagnostic consistency of the three doctors in conventional 2D images and 3D CS⁃SPACE images was
analyzed respectively，and the diagnostic consistency between the two sets of images was evaluated. Results：In the objective
evaluation of image quality，SNR and CNR of 3D CS⁃SPACE image were obviously better than that of conventional 2D image. For the
two groups of images，two doctors’ratings of 3D CS⁃SPACE images were significantly higher than those of conventional 2D images，and
