EllisMichele R. Aizenberg 3 mm also decreased the accuracy of motor mapping results from individual sessions to the precision maps (p < 0.001). With cluster significance thresholding, mean false positive voxel percentages remained below 5% for both methods across the tested kernel widths. Both Gaussian and constrained smoothing demonstrated a biasing effect on the resting state connectivity of nearby regions and on the graph theory metrics of the functional connectomes.ConclusionThis study showed that unconstrained Gaussian smoothing spreads activation across cortical boundaries, increases white matter activation, and biases graph theory connectivity metrics. Anatomically constrained smoothing reduced some of these smoothing artifacts while still increasing reliability and may be a reasonable alternative to unconstrained Gaussian smoothing.]]> https://www.frontiersin.org/articles/10.3389/fnimg.2026.1776934 https://www.frontiersin.org/articles/10.3389/fnimg.2026.1776934 <![CDATA[Gadolinium-based contrast agent-free (GBCA-free) versus gadolinium-based contrast agent-enhanced (GBCA-enhanced) magnetic resonance imaging as a screening tool for intracranial tumors]]> 2026-04-28T00:00:00Z Original Research Haider Faeq Hadhratee Al-RubaieeSamr Adnan Abdaljabbar Al-SalmWeronika JensenAgnieszka Monika DelektaYousef YavarianBoris Modrau https://www.frontiersin.org/articles/10.3389/fnimg.2026.1736950 https://www.frontiersin.org/articles/10.3389/fnimg.2026.1736950 <![CDATA[Comparison of commercial 1Tx32Rx vs. 8Tx32Rx head coils for routine 7T neuroimaging]]> 2026-03-25T00:00:00Z Original Research Carina GrafBelinda DingCatarina RuaKrzysztof KlodowskiChristopher T.
