Objectives: Magnetic resonance imaging (MRI) is a non-ionizing imaging modality with excellent soft-tissue contrast, ideal for pediatric patients who are more sensitive to radiation. However, challenges such as motion, sedation risks, and anatomical differences require optimized protocols. This study aims to develop and implement pediatric-specific MRI techniques to improve image quality, reduce sedation, and enhance safety. By evaluating current practices and applying advancements like faster sequences and motion correction, the study seeks to establish evidence-based, child-centered protocols for improved diagnostic accuracy and patient outcomes. Methods: This prospective observational study, conducted in three phases, analyzed existing MRI protocols, developed optimized techniques, and assessed their impact on image quality, safety, and diagnostic accuracy in pediatric patients. Post-implementation surveys evaluated clinician satisfaction. Ethical clearance and informed parental consent were obtained before initiating the study. Results: This study included 350 pediatric patients, with 200 assessed retrospectively in phase 1 (baseline group) and 150 assessed prospectively following the implementation of optimized protocols in phase 3 (intervention group). The distribution of patients across age groups was as follows: infants (0-2 years): 30% (n=105); young children (3-6 years): 35% (n=123); older children and adolescents (7-18 years): 35% (n=122). There was no significant statistical difference in age or gender distribution between the baseline and intervention groups (p=0.76). Conclusion: This study reinforces and expands current knowledge on optimized pediatric MRI protocols, demonstrating benefits such as reduced scan duration, improved image quality, and lower sedation rates. These tailored protocols enhance patient safety and diagnostic accuracy while addressing key challenges in pediatric imaging. Incorporating motion correction, fast sequences, and non-pharmacological techniques, the protocols proved clinically effective, supported by positive feedback from radiologists and MRI technicians. Overall, this study highlights the importance of patient-centered, evidence-based pediatric MRI practices.
