Abstract
Background: Contrast-enhanced mammography (CEM) is an emerging alternative to breast magnetic resonance imaging (MRI) for detecting breast cancer, offering lower cost and shorter acquisition time. However, comparative diagnostic accuracy remains uncertain.

Objective: To compare the diagnostic performance of CEM versus breast MRI for breast cancer detection using a systematic review and meta-analysis.

Methods: We searched PubMed, Scopus, and Web of Science up to January 2026 for studies reporting sensitivity and specificity of both CEM and MRI in the same population, using histopathology or follow-up as reference standard. We calculated pooled sensitivity, specificity, diagnostic odds ratio (DOR), and area under the summary receiver operating characteristic curve (AUC). Quality was assessed using QUADAS-2.

Results: Fifteen studies (2,148 patients) met inclusion criteria. Pooled sensitivity was 94% (95% CI: 91–96%) for CEM and 96% (95% CI: 93–98%) for MRI (p=0.12). Pooled specificity was 87% (95% CI: 83–90%) for CEM and 84% (95% CI: 80–88%) for MRI (p=0.09). DOR was 118 (95% CI: 72–194) for CEM and 132 (95% CI: 78–223) for MRI. AUC was 0.97 for CEM and 0.98 for MRI. No significant heterogeneity was found (I²<50% for most analyses).

Conclusion: CEM demonstrates comparable diagnostic accuracy to breast MRI for breast cancer detection, with slightly lower sensitivity but similar specificity. CEM may serve as an accessible alternative where MRI is unavailable or contraindicated.
