Oscillating steady-state imaging (OSSI): A novel method for functional MRI.
Shouchang GuoDouglas C NollPublished in: Magnetic resonance in medicine (2020)
OSSI is a new acquisition method that exploits a large, oscillating signal that is T 2 ∗ -weighted and suitable for fMRI. The steady-state signal from balanced gradients creates higher signal strength than single slice GRE at varying TEs, enabling greater volumes of functional activity and higher SNR for high-resolution fMRI.
