Abstract:
Purpose Accurate diagnosis of triangular fibrocartilage (TFC) tear is very important for treatment. MRI is most used for diagnosing TFC tear. This paper aims to evaluate MRI and MR arthrography (MRA) for diagnosing TFC tear by meta-analysis. Materials and Methods The articles were searched in the databases such as Wanfang, VIP, CNKI, Cochrane Library, Medline, Embase and PubMed. The QUADAS items were used to evaluate the quality of the included studies. Heterogeneity of the included articles was tested. The pooled weighted sensitivity and specificity of MRI and MRA in diagnosing TFC tear were calculated, and the pooled receiver operation curve was drawn. Results Fifteen articles met the inclusion criteria, 2 were Chinese articles and 13 were English articles. The subjects and methods of the articles were different and existed heterogeneity. The sensitivity and specificity of MRI for diagnosing TFC tear were 0.66 (95% CI 0.61-0.71) and 0.75 (95% CI 0.69-0.81), and those of MRA were 0.80 (95% CI 0.73-0.87) and 0.86 (95% CI 0.74-0.93). The area under curve and Q* index of SROC of MRI were 0.8566 and 0.7875, respectively. The area under curve and Q* index of SROC of MRA were 0.9123 and 0.8446, respectively. Conclusion The accuracy of TFC tear avulsion for MRA are higher than for MRI, when there is unclear of TFC avulsion using MRI, MRA can be used for diagnosis.
