Numerous quantitatively studies have focused on the diagnosis of bursal-sided partial-thickness rotator cuff tears (RCTs); however, the accuracy of magnetic resonance imaging (MRI) and MR arthrography (MRA) remains inconclusive. This study was performed systematically to compare the diagnostic value of MRA and MRI for the bursal-sided partial-thickness RCTs.
Three electronic databases, PubMed, Embase, and Cochrane Library, were utilized to retrieve articles comparing the diagnostic value of MRA and MRI for detecting bursal-sided partial-thickness RCTs. After screening and diluting out the articles that met the inclusion criteria to be used for statistical analysis, the pooled evaluation indexes include sensitivity, specificity, positive and negative predictive values, diagnostic odds ratio (DOR), and the area under the receiver operating characteristic curve (AUC).
Twelve studies involving 1740 patients and 1741 shoulders were identified. The pooled sensitivity, specificity, DOR, and AUC of MRA to diagnose bursal-sided partial-thickness RCTs were 0.77 (95% CI, 0.67-0.85), 0.98 (95% CI, 0.95-0.99), 73.01 (95% CI, 35.01-152.26), and 0.88 (95% CI, 0.85-0.91), respectively. The pooled sensitivity, specificity, DOR, and AUC of MRI were 0.77 (95% CI, 0.66-0.86) and 0.96 (95% CI, 0.81-0.99), and 37.12 (95% CI, 8.08-170.64) and 0.82 (95% CI, 0.78-0.85), respectively.
This meta-analysis reveals that MRA and MRI have similar diagnostic value for the diagnosis of bursal-sided partial-thickness rotator cuff tears.
大量定量研究集中在肩峰下滑囊侧部分厚度肩袖撕裂（RCT）的诊断上；然而，磁共振成像（MRI）和磁共振关节造影（MRA）的准确性仍不确定。本研究系统地比较了 MRA 和 MRI 对肩峰下滑囊侧部分厚度 RCT 的诊断价值。
利用三个电子数据库，PubMed、Embase 和 Cochrane Library，检索比较 MRA 和 MRI 对肩峰下滑囊侧部分厚度 RCT 诊断价值的文章。筛选出符合纳入标准并用于统计分析的文章后，汇总评估指标包括敏感性、特异性、阳性和阴性预测值、诊断比值比（DOR）和受试者工作特征曲线下面积（AUC）。
共纳入 12 项研究，涉及 1740 例患者和 1741 个肩部。MRA 诊断肩峰下滑囊侧部分厚度 RCT 的汇总敏感性、特异性、DOR 和 AUC 分别为 0.77（95%CI，0.67-0.85）、0.98（95%CI，0.95-0.99）、73.01（95%CI，35.01-152.26）和 0.88（95%CI，0.85-0.91）。MRI 的汇总敏感性、特异性、DOR 和 AUC 分别为 0.77（95%CI，0.66-0.86）和 0.96（95%CI，0.81-0.99）、37.12（95%CI，8.08-170.64）和 0.82（95%CI，0.78-0.85）。
本荟萃分析表明，MRA 和 MRI 对肩峰下滑囊侧部分厚度 RCT 的诊断具有相似的诊断价值。
