FIG 1. Various MR images are shown for comparison.
A, Sagittal MR image shows outlines of multisection (two upper boxes) and PRESS (lower box) volumes of interest.
B, Axial T1-weighted MR image shows defined PRESS volume (inner box), field of view (outer box), and positions of the individual voxels extracted for data analysis (circles).
C, Ventricular proton density–weighted axial MR image displaying positions of selected voxels for multisection data analysis (circles).
D, Supraventricular proton density–weighted axial MR images displaying positions of selected voxels for multisection data analysis (circles).
FIG 2. Spectrum selected in normal-appearing white matter (left) and spectrum from a white matter signal hyperintensity (right) show evident reduction in the NAA peak amplitude at 2.02 ppm in the latter
FIG 3. Scatter plot displays the correlation between white matter signal hyperintensity and ventricular volumes for patients with lacunes. FIG 4. Scatter plot displays the correlation between cortical and ventricular volumes for patients with lacunes. FIG 5. Scatter plot displays the correlation between frontal cortical NAA and supratentorial lacune count for all patients with lacunes
