FIGURE 2.

Neuroanatomical fidelity. Shown are representative examples of brain images collected during a single imaging session using a multi‐slice spin echo, RARE (rapid acquisition with relaxation enhancement) pulse sequence. The row on the bottom shows axial sections collected during the anatomical scan taken at the beginning of each imaging session using a data matrix of 18 slices; 0.75 mm thickness; FOV 1.8 cm²; data matrix 128 × 128. The row above shows the same images but collected for functional analysis using HASTE, a RARE pulse sequence modified for faster acquisition time. These images were acquired using the same field of view and slice anatomy but a larger data matrix of 96 × 96. Note the anatomical fidelity between the functional images and their original anatomical image. The absence of any distortion is necessary when registering the data to atlas to resolve 132 segmented brain areas.
