متن کاملNormalization of Magnetization Transfer Ratio MRI For Multicentre Clinical Trials
Introduction Magnetization transfer ratio (MTR) magnetic resonance (MR) imaging is a promising technique for measuring in vivo demyelination and remyelination, providing a more direct measurement of activity in diseases like multiple sclerosis (MS). Incorporation of MTR in multicentre imaging protocols is feasible using stock sequences and MT pulses. However, such MTR values are sequence and sc...
متن کاملMagnetization Transfer Prepared Gradient Echo MRI for CEST Imaging
Chemical exchange saturation transfer (CEST) is an emerging MRI contrast mechanism that is capable of noninvasively imaging dilute CEST agents and local properties such as pH and temperature, augmenting the routine MRI methods. However, the routine CEST MRI includes a long RF saturation pulse followed by fast image readout, which is associated with high specific absorption rate and limited spat...

متن کاملMRI of the human eye using magnetization transfer contrast enhancement.
PURPOSE To determine the feasibility of using magnetization transfer contrast-enhanced magnetic resonance imaging (MRI) to track cataractous lens changes. METHODS A fast spin-echo sequence was modified to include a magnetization transfer contrast (MTC) preparation pulse train. This consisted of twenty 8.5-msec sinc pulses, 1200 Hz upfield from the water resonance and 1.2-Hz power. The MTC pre...
