Focused Abbreviated Survey MRI Protocols for Brain and Spine Imaging

Area of Science:

• Radiology
• Medical Imaging
• Neuroradiology

Background:

• Magnetic Resonance Imaging (MRI) is a powerful diagnostic tool, but long scan times limit its use in emergencies.
• Rapid and abbreviated MRI protocols aim to reduce imaging times and improve efficiency for specific clinical questions.

Purpose of the Study:

• To review focused abbreviated survey techniques (FAST) MRI protocols.
• To provide a practical overview of FAST MRI for neuroradiologists, covering techniques, institutional protocols, and future directions.

Main Methods:

• Review of accelerated imaging techniques used to reduce MRI scan times.
• Description of specific FAST MRI protocols employed at the authors' institution.
• Discussion of the clinical application of FAST protocols for screening emergent or urgent conditions.

Main Results:

• FAST protocols provide adequate diagnostic image quality with significantly reduced imaging times.
• These protocols enable efficient confirmation or exclusion of actionable findings in emergent settings.
• FAST MRI serves as a critical diagnostic screening tool, enhancing clinical workflow.

Conclusions:

• FAST MRI protocols are effective alternatives to standard MRI for specific clinical scenarios, particularly in emergent situations.
• The review provides a comprehensive guide to FAST MRI for practicing neuroradiologists.
• Accelerated MRI techniques are crucial for expanding the utility of MRI in time-sensitive clinical environments.
