The findings of this review underscore the pivotal role of cardiac MRI in the diagnostic and prognostic evaluation of patients following SCA. By providing detailed tissue characterization and functional assessments, cardiac MRI complements standard diagnostic pathways and informs treatment decisions. However, significant challenges remain in its clinical application. The variability in imaging protocols, timing of MRI post-SCA, and reporting standards across studies underscores the need for standardized guidelines. The heterogeneity observed in this review highlights the necessity for consensus-driven research to address existing gaps. Future studies should incorporate comparator groups, standardized imaging protocols, and robust follow-up data to enhance the interpretability and reliability of findings. Moreover, the development of multicenter, randomized controlled trials could provide more definitive evidence for the role of cardiac MRI in this context.

Cardiac MRI represents a valuable tool for both diagnostic clarity and prognostic assessment in patients following SCA. Its ability to detect myocardial abnormalities, guide therapeutic interventions, and predict adverse outcomes positions it as an indispensable modality in modern cardiology. However, the challenges identified in this review emphasize the need for standardization and further research to optimize its use. Addressing these issues will not only improve patient outcomes but also strengthen the evidence base for integrating cardiac MRI into routine clinical practice.
