A combined analytical solution for chemical exchange saturation transfer and semi-solid magnetization transfer.
Off-resonant RF irradiation in tissue indirectly lowers the water signal by saturation transfer processes: on the one hand, there are selective chemical exchange saturation transfer (CEST) effects originating from exchanging endogenous protons resonating a few parts per million from water; on the other hand, there is the broad semi-solid magnetization transfer (MT) originating from immobile pro...
متن کاملAnalytical determination of the chemical exchange saturation transfer (CEST) contrast in molecular magnetic resonance imaging
Magnetic resonance based on molecular imaging allows tracing contrast agents thereby facilitating early diagnosis of diseases in a non-invasive fashion that enhances the soft tissue with high spatial resolution. Recently, the exchange of protons between the contrast agent and water, known as the chemical exchange saturation transfer (CEST) effect, has been measured by applying a suitable pulse ...

The baseline and the magnetization transfer (MT) line were omitted from Figure 1a during the typesetting of the Article. The correct Figure 1 appears below.
متن کاملUniform magnetization transfer in chemical exchange saturation transfer magnetic resonance imaging
The development of chemical exchange saturation transfer (CEST) has led to the establishment of new contrast mechanisms in magnetic resonance imaging, which serve as enablers for advanced molecular imaging strategies. Macromolecules in tissues and organs often give rise to broad and asymmetric exchange effects, called magnetization transfer (MT) effects, which can mask the CEST contrast of inte...
متن کاملSimplified and scalable numerical solution for describing multi-pool chemical exchange saturation transfer (CEST) MRI contrast.
Chemical exchange saturation transfer (CEST) imaging is sensitive to dilute labile proton and microenvironment properties such as pH and temperature, and provides vital information complementary to the conventional MRI methods. Whereas the Bloch equations coupled by exchange terms (i.e., Bloch-McConnell equations) have been utilized to quantify 2-pool CEST contrast, it is tedious to extend the ...
