To determine the diagnostic accuracy of native magnetic resonance imaging (MRI) regarding different ligamentous lesions of the wrist and to analyze the influence of technical characteristics, such as field strength, application of fat saturation, 3-dimensional sequences, and wrist coils. A systematic search was performed using MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases. Studies that were published before February 12, 2024, were included. All studies comparing the diagnostic accuracy of native wrist MRI with that of wrist arthroscopy for suspected ligamentous lesions were included. Results were analyzed by anatomic localization and technical aspects of the MRI. To assess the quality of included studies, we used the revised Quality Assessment of Diagnostic Accuracy Studies tool. The systematic search revealed 5,181 articles. Thirty-seven studies, reporting 3,893 ligamentous lesions, were eligible for inclusion. The studies displayed heterogeneity in terms of technical conditions, such as field strength, the use of wrist coils, the application of 3-dimensional sequences, and fat saturation. Research methods also varied. Overall sensitivity and specificity were 0.78 (0.66-0.86) and 0.81 (0.70-0.89) for 1.5-T MRI, whereas sensitivity was 0.73 (0.68-0.78) and specificity was 0.90 (0.59-0.98) for 3-T MRI. There was no significant difference between the 2 subgroups (P = .3807 and P = .4248). Sensitivity was 0.82 (0.75-0.87) for triangular fibrocartilage complex lesions, 0.63 (0.50-0.74) for scapholunate ligament tears, and 0.41 (0.25-0.60) for lunotriquetral ligament lesions. Specificity for triangular fibrocartilage complex lesions was 0.82 (0.73-0.89), for scapholunate ligament tears was 0.86 (0.73-0.93), and for lunotriquetral ligament lesions was 0.93 (0.81-0.98). The sensitivity and specificity of MRI are influenced by the anatomic location of the lesion and technical conditions. In terms of diagnostic accuracy, no significant difference was found between 1.5-T and 3-T MRI. Level III, systematic review of Level II-III studies.
