Summary
Two new accelerated MRI protocols, GOBrain and Deep Resolve Swift Brain, offer fast pediatric brain imaging. These methods enable quick, diagnostically sufficient scans for emergency settings, improving patient care.
Area of Science:
- Radiology
- Medical Imaging
- Neuroimaging
Background:
- Pediatric brain MRI is challenged by patient motion, uncooperative behavior, and sedation needs, especially in emergencies.
- There is a clinical need for rapid MRI protocols that maintain diagnostic image quality for pediatric neuroimaging.
- Existing turbo spin-echo (TSE) protocols use parallel imaging (PI) and simultaneous multi-slice (SMS) for faster scans.
Purpose of the Study:
- To evaluate two accelerated MRI protocols, GOBrain and Deep Resolve Swift Brain, for pediatric brain imaging at 3 Tesla.
- To assess the clinical feasibility of these protocols in diverse pediatric neurological cases.
- To determine if these protocols can provide diagnostically sufficient images in reduced scan times for emergency and triage situations.
Main Methods:
- Evaluation of Siemens Healthineers' GOBrain (DL-based reconstruction) and Deep Resolve Swift Brain (multi-shot EPI with DL reconstruction) protocols.
- Application of protocols to clinically relevant pediatric cases, including various pathologies.
- Utilizing advanced techniques like 3D volumetric encoding, compressed sensing, and deep learning (DL) for accelerated imaging.
Main Results:
- Both GOBrain and Deep Resolve Swift Brain protocols demonstrated potential for rapid, comprehensive multi-contrast pediatric brain MRI examinations.
- Scans suitable for triage and emergency imaging can be completed in minutes.
- The protocols showed clinical feasibility across cases like leukemia-related leukoencephalopathy, brain abscess, and traumatic injury.
Conclusions:
- Accelerated MRI protocols like GOBrain and Deep Resolve Swift Brain offer valuable supplementary options for pediatric neuroimaging.
- These protocols can significantly reduce examination time, benefiting emergency and triage scenarios.
- Further comparative studies are needed, and high-resolution protocols may still be required for subtle findings.

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
