Abstract：
UNASSIGNED: To explore the early diagnostic value of superb microvascular imaging (SMI) features within the rotator cuff gap for frozen shoulder.
UNASSIGNED: This prospective study enrolled patients with acute early-stage frozen shoulder seeking treatment at Zhabei Central Hospital in Jing\'an District, Shanghai, between July 2021 and December 2022 were enrolled in this study. Healthy controls were collected in a 1:1 ratio from the same hospital\'s physical examination center. All participants underwent SMI and power Doppler ultrasound (PDUS) of the rotator cuff gap.
UNASSIGNED: The study included 79 patients with frozen shoulder and 77 healthy controls. Compared with the healthy control group, the patient group had a higher proportion of hypoechoic rotator cuff gap (81.0% vs 48.1%, P<0.001), a thicker coracohumeral ligament (2.60±1.01 vs 2.03±0.97, P<0.001), a thicker glenohumeral joint capsule (3.10±0.99 vs 2.46±1.17, P<0.001), and elevated blood grading using SMI (P<0.001) and PDUS (P=0.014). The highest area under the curve (AUC) was observed for SMI blood flow grading (AUC=0.824, 95% CI: 0.755-0.880, P<0.001), resulting in 82% sensitivity and 77% specificity when using a cutoff of 1. SMI blood flow grading was associated with external rotation <30° (P=0.007) and abduction <30° (P=0.013) but not with internal rotation <30° (P=0.630) or flexion <30° (P=0.562).
UNASSIGNED: The grading of SMI blood flow may emerge as a valuable predictive indicator for the early stages of frozen shoulder. This simple ultrasound technique holds the potential to enhance the diagnostic process, enabling early initiation of treatment and potentially improving patient outcomes.

摘要：
■探讨肩袖间隙内出色的微血管成像（SMI）特征对冻结肩的早期诊断价值。
■这项前瞻性研究招募了在静安区闸北中心医院寻求治疗的急性早期冻结肩患者，上海,2021年7月至2022年12月纳入本研究.从同一医院的体格检查中心以1:1的比例收集健康对照。所有参与者都接受了SMI和肩袖间隙的能量多普勒超声（PDUS）。
■该研究包括79名肩周炎患者和77名健康对照。与健康对照组相比,患者组低回声肩袖间隙的比例较高(81.0%vs48.1%,P<0.001)，角膜韧带较厚（2.60±1.01vs2.03±0.97，P<0.001），肱骨关节囊较厚（3.10±0.99vs2.46±1.17，P<0.001），使用SMI（P<0.001）和PDUS（P=0.014）的血液分级升高。SMI血流分级曲线下面积(AUC)最高(AUC=0.824,95%CI:0.755-0.880,P<0.001),当使用1的截止值时，灵敏度为82%，特异性为77%。SMI血流分级与外旋<30°（P=0.007）和外展<30°（P=0.013）相关，与内旋<30°（P=0.630）或屈曲<30°（P=0.562）无关。
■SMI血流量的分级可能是冻结肩早期的有价值的预测指标。这种简单的超声技术具有增强诊断过程的潜力，使治疗的早期开始和潜在的改善患者的结果。
