MRI Techniques to Decrease Imaging Times in Children

Area of Science:

• Radiology
• Medical Imaging
• Pediatric Imaging

Background:

• Long MRI acquisition times pose challenges for pediatric imaging.
• Sedation or general anesthesia is often required, increasing costs and risks.
• Reducing scan times can improve patient comfort and reduce the need for anesthesia.

Purpose of the Study:

• To review current and emerging techniques for reducing MRI scan times in pediatric patients.
• To discuss the concepts, data, applications, and products associated with these time-saving strategies.
• To explore the potential of new technologies to further decrease imaging duration.

Main Methods:

• Review of commercially available imaging techniques: parallel imaging, simultaneous multisection imaging, radial k-space acquisition, compressed sensing MRI reconstruction, and automated protocol selection.
• Discussion of emerging techniques: AI-based reconstruction, gradient-controlled aliasing sampling and reconstruction, 3D MR spectroscopy, and prospective motion correction.

Main Results:

• Several techniques are commercially available and increasingly used to shorten MRI scan times.
• Emerging technologies show promise for further significant reductions in imaging duration.
• These advancements aim to mitigate the need for sedation or anesthesia in pediatric MRI.

Conclusions:

• Advanced MRI techniques are crucial for efficient pediatric imaging.
• Ongoing research into novel methods promises to further optimize scan times.
• Reducing MRI acquisition duration enhances patient safety and diagnostic accessibility.
