Summary
Echo Planar Imaging (EPI) offers rapid human imaging under 100 ms. Recent advances include EPISTAR for perfusion imaging and EPSI for faster spectroscopic imaging, enhancing brain functional imaging applications.
Area of Science:
- Magnetic Resonance Imaging (MRI)
- Neuroimaging techniques
Context:
- Echo Planar Imaging (EPI) is a fast MRI sequence enabling rapid image acquisition (<100 ms).
- EPI is widely used for functional imaging, diffusion imaging, T2 imaging, and perfusion imaging.
- Recent developments focus on advanced EPI applications for brain imaging.
Purpose:
- To review recent advancements in Echo Planar Imaging (EPI) for neuroimaging.
- To highlight novel EPI techniques like EPISTAR and EPSI.
- To discuss the applications and benefits of these new EPI methods.
Summary:
- EPI enables rapid human imaging, crucial for dynamic physiological processes.
- EPISTAR (spin targeting perfusion imaging) isolates inflow changes during brain activation, differentiating from BOLD imaging.
- EPSI (high-speed spectroscopic imaging) significantly reduces signal acquisition time.
Impact:
