Abstract :
Milestones are the predicted points at which a child is expected to reach a certain developmental stage, like talking or walking. In the case when a child does not achieve a significant stage by the predicted age, it is known as a delayed milestone. Delayed milestones might have a variety of causes, including issues throughout pregnancy or delivery, genetic issues, and premature birth. Delays in milestones might result from issues that arise in infancy or early, like infections or head injuries. Frequently, no clear cause is found. This study aims to search in main causes that lead to increase developmental delay in pediatric and to confirm the MRI is superior modality that use to give true diagnosis. A prospective study was conducted on 65 individuals who had their developmental delay assessed using brain magnetic resonance imaging (MRI). The research was carried out at Children's Central Teaching Hospital and Medical City from August to October of 2022 G.C. In all, 65 patients have been included in the study; of these, 28 had 43.1% female patients and 37 had 56.9% male patients. A total of fifty individuals had abnormal brain MRI results, while fifteen patients had normal results. In children who have not reached their developmental milestones, MRI is a valuable investigative tool; in our study, a significant percentage of brain MRI abnormalities were found. Because of its ability to resolve soft tissues, MRI has frequently aided in the diagnosing process.
