Global developmental delay (GDD) is a significant challenge faced by the pediatric population. Early identification and intervention are crucial for a better outcome. Magnetic resonance imaging (MRI) is a non-invasive imaging modality that can be used to evaluate children with GDD. This paper aims to review the role of MRI in the evaluation of children with GDD. Aim: This study aimed to evaluate MRI imaging features in children with developmental delay. The current study was a cross-sectional study conducted in the Department of Radio-diagnosis at SMS Hospital, Jaipur, Rajasthan. Results: In our study, a total of 80 children who were clinically suspected of global development delay were evaluated between the age group of 3 months to 18 years using 3T MRI It was found that 71% of cases had abnormal MRI findings. This study provides a systematic approach to the causes of developmental delay in children and the importance of MRI investigation. Conclusion: We conclude from our study that MRI is the most useful investigation in patients clinically suspicious of developmental delay and can help in diagnosing the underlying aetiology.
