Axial MR Images at Basal Ganglia in 63-Year-Old Woman With Subjective Cognitive Impairment

Caption

Conventional 3D T1W image (A) without segmentation, (B) with segmentation by Neuroquant, and (C) with segmentation by Freesurfer; ultrafast 3D-EPI T1W image (D) without segmentation, (E) with segmentation by Neuroquant, and (F) with segmentation by Freesurfer. Pallidum (asterisks) appears larger for Freesurfer (C, F) than for NeuroQuant (B, E), but appears similar in size between two sequences for each software package. For both software packages, bilateral frontal and occipital cortices (B, C) at bone-tissue interface appear more color-coded for conventional than for ultrafast sequence, contributing to larger cortical gray matter for conventional sequence.
