Spin‐echo and gradient‐echo epi of human brain activation using bold contrast: A comparative study at 1.5 T
Abstract
In this study, Blood Oxygenation Level Dependent (BOLD) contrast in the detection of human brain activation was compared between spin‐echo and gradient‐echo echo‐planar sequences at 1.5 T. Time course series of spin‐echo and gradient‐echo images containing the primary motor cortex were collected during rest (no finger movement) and activation (finger movement). Each time course series was collected using a different TE. Resting and active state signal intensities at each TE were measured in identical regions in the motor cortex. From these data, resting and active state R2 (1/T2) and R (1/T) values were obtained. Across four subjects, brain activation produced an average R2 change of −0.16±0.02/s (±SE), and an average R change of −0.55±0.08/s. The average Δ R/Δ R2 ratio was 3.52±0.56. The average gradient‐echo/spin‐echo ratio of activation‐induced signal changes at the TE for maximal BOLD contrast for each sequence (TE≈T and T2) was calculated to be 1.87±0.40.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
