Physiological Contribution in Spontaneous Oscillations: An Approximate Quality - Assurance Index for Resting-State fMRI Signals
For validating the sensitivity of the proposed PICSO index (a new quality-assurance index for resting state fMRI) to functional connectivity, both fMRI dataset of phantom and human during resting state were acquired. The resting-state human dataset (n=12, age: 26.4 ± 2.1 y, females/males: 6/6) was acquired at four image resolutions:
- 1.3 × 1.3 × 2 mm3
- 2 × 2 × 2 mm3
- 3 × 3 × 3 mm3
- 5 × 5 × 5 mm3
Moreover, a spherical water phantom was scanned using identical imaging protocols. Besides, T1-weighted structural images and B0 field map were acquired as well.
Code and same data are included as well.
