文摘
- •
fMRI with CBV-mapping is combined with a simultaneous multi-slice readout.
- •
FOV is increased up to a factor of 4 to enable near whole-brain coverage.
- •
High SNR allows high-resolution imaging up to 1 × 1 × 1.2 mm3.
- •
Higher specificity to GM tissue of CBV-fMRI compared to GE-BOLD is confirmed.
