The sensitivities, specificities, likelihood ratios, and diagnostic odds ratio (DOR) were confirmed. The symmetric receiver operator characteristic curve (SROC) was used to assess the threshold of T2 mapping and Dixon. Fagan\u2019s nomogram was drawn. Meta-regression and subgroup analyses were applied to distinguish the sources of heterogeneity among the included studies.

The combined sensitivity of T2 mapping was 0.70 [95% CI (0.65\u20130.75)], specificity was 0.84 [95% CI (0.75\u20130.90)], area under the SROC curve (AUC) was 0.78 [95% CI (0.75\u20130.82)], and DOR was 12. The combined sensitivity of Dixon was 0.74 [95% CI (0.58\u20130.85)], specificity was 0.80 [95% CI (0.58\u20130.93)], AUC was 0.83 [95% CI (0.80\u20130.86)], and DOR was 11.66. The Deeks\u2019 funnel plot showed no existing publication bias. The prospective design, partial verification bias, and blinding contributed to the heterogeneity in specificity and sensitivity. The post-test probability of T2 mapping in TAO patients\u2019 disease activity was 75%, and the post-test probability of Dixon in TAO was 87%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Compared with T2 mapping, Dixon presented a significantly higher sensitivity and AUC for detecting TAO disease activity.
