Abstract

Overview

Current research in radiological safety is intensely focused on assessing the risks associated with imaging technologies. This study specifically addresses the safety of MRI imaging in pediatric patients.

Findings

  • Biological Effects of EMF: The study reviews the biological impacts of the non-ionizing electromagnetic fields used in MRIs, highlighting potential risks such as polarization, induced current, and thermal heating.
  • Acoustic Noise: Concerns are raised about the noise generated during MRI scans, which could pose risks to young patients.
  • Ferromagnetic Risks: There is a higher likelihood of incidents involving ferromagnetic materials brought into MRI settings inadvertently, particularly affecting children more than adults.
  • Sedation and Anesthesia: The necessity for sedation or general anesthesia due to the prolonged duration of MRI exams in very young patients introduces additional risks.
  • Gadolinium-based Contrast Agents: A special focus on the risks from these agents, especially considering recent findings on brain deposition.

Conclusion

This comprehensive review strongly points to the inherent risks in pediatric MRI examinations, urging for a cautious approach and calling for thorough investigations on the long-term effects of such exposures.
