Magnetization Transfer Mri. Mt can be used to improve lesion contrast of gadolinium enhanced brain lesions on t1 weighted spin echo images. Magnetization transfer mt is a unique contrast mechanism enabling detection and quantification of otherwise mrinvisible macromolecules.
A qualitative description of how mt works is provided along with experimental evidence that leads to a quantitative model for mt in tissues. Magnetization transfer mr imaging is a technique that increases the contrast of enhancing and non enhancing lesions by suppressing background signal and is achieved by selectively saturating the signal from the immobile water protons. Does not affect fluids lcr blood urine containing no bound protons.

Typically mri exploits water protons to form images and the contrast between tissue types is driven largely by. There is some ambiguity regarding the precise definition of magnetization transfer however the general definition given above encompasses all more specific notions. Magnetization transfer a new technique for improving image contrast in magnetic resonance mr imaging is based on application of off resonance radio frequency pulses and observing their effects on mr images as well as measuring the signal intensity with and without application of the pulses ie magnetization transfer ratio mtr.
