Spiral K‐space MR imaging of cortical activation
Abstract
Brain function can be mapped with magnetic resonance (MR) imaging sensitized to regional changes in blood oxygenation due to cortical activation. Several MR imaging methods, including conventional imaging and echo‐planar imaging, have been successfully used for this purpose. The authors investigated spiral k‐space MR imaging, implemented with an unmodified 1.5‐T clinical imager, for imaging of cortical activation. A gradient‐echo, spiral k‐space imaging method was used to measure activation in the primary visual cortex (number sequence task), primary motor cortex (fist‐clenching task), and prefrontal cortex (verbal fluency task). Comparison of conventional and spiral k‐space imaging in the visual and motor cortex, in which signal‐to‐noise ratio, voxel size, and imaging time were matched, showed that artifacts were reduced with the spiral k‐space method, while the area and degree of activation were similar. The number of sections that could be imaged in a fixed time interval was increased by a factor of four with this implementation of spiral k‐space imaging compared with conventional imaging.

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.
