Abstract Spin-lock based functional magnetic resonance imaging (fMRI) has the potential for direct spatially-resolved detection of neuronal activity and thus may represent an important step for basic research in neuroscience. In this work. the corresponding fundamental effect of Rotary EXcitation (REX) is investigated both in simulations as well as in phantom and in vivo experiments. ... https://safeersappliancers.shop/product-category/faber-high-light-rad-brs-wh-matt-a91-matt-white-91cm-110-0456-206-cooker-hood/
