DL-based reconstruction enables ultrafast, motion-robust T2-weighted single-shot brain MRI in children without increasing acquisition time.
The hybrid DL framework integrates compressed sensing with two CNNs to improve image sharpness, contrast-to-noise ratio, and artifact suppression.
This approach reduces the need for sedation in pediatric MRI by improving image quality in awake, motion-prone children.

Use DL-enhanced single-shot T2-weighted MRI sequences to improve diagnostic image quality in pediatric brain imaging.
Apply quantitative metrics such as apparent contrast-to-noise ratio and apparent signal-to-noise ratio for image quality assessment.

Implement DL-based reconstruction frameworks that combine compressed sensing and CNNs to reduce motion artifacts and acquisition time.
Prefer sedation-free imaging protocols when possible, especially in older pediatric patients, to improve safety and workflow.

Monitor image quality improvements using standardized ROI-based quantitative analysis in frontal cortex, white matter, and mastoid cells.
Assess patient compliance and motion during MRI to tailor imaging protocols accordingly.

Consider potential limitations of DL reconstruction in very young or uncooperative children where sedation may still be required.
Be aware of the need for vendor-specific DL algorithms and their validation in pediatric populations.

62 pediatric patients aged 0 to <18 years undergoing clinically indicated brain MRI, including sedated and awake subgroups.

DL-based reconstruction improved image quality in both sedated and awake children, supporting sedation-free protocols especially in older children.

Obtain informed consent from legal guardians prior to pediatric MRI with DL-based reconstruction.
Use vendor-provided DL reconstruction frameworks integrating compressed sensing and CNNs for enhanced image quality.
Customize MRI protocols based on patient age, clinical indication, and cooperation level to optimize diagnostic yield.
Incorporate quantitative image quality metrics for objective assessment and protocol optimization.
Aim to minimize sedation by leveraging motion-robust, ultrafast DL-enhanced imaging techniques.
