Magnetization transfer contrast imaging of hepatic neoplasms.
A method of performing magnetization transfer contrast (MTC) using a pulse sequence based on a series of on-resonance binomial pulses preceding a conventional spin-echo sequence has been recently described. We investigated this technique in the evaluation of circumscribed hepatic neoplasms on a 0.5 T imager. Conventional spin-echo imaging was performed in 18 patients with hepatic neoplasms, 15 ...
متن کاملDiffusion-weighted EPI with magnetization transfer contrast.
Capabilities of diffusion-weighted (DW) and magnetization transfer (MT) imaging are well established for tissue characterization in various pathologies individually. However, the effect of suppression of macromolecules on applying MT pulse on signals associated with DW imaging and resulting change in the apparent diffusion coefficient (ADC) of water molecules has not been demonstrated previousl...

متن کاملChimera Averaging for Robust SSFP Magnetization Transfer Contrast Imaging (MT-Chimera)
Introduction Recent studies [1] revealed that balanced SSFP shows a pronounced magnetization transfer (MT) contrast, which can be altered via the RF pulse duration and thus allows for quantitative MT imaging [2]. It is thereby assumed that changes in signal intensity are due to the MT effect alone. However, elongated RF pulses entail a prolonged TR, which may introduce signal variations due to ...
متن کاملMagnetization transfer imaging of the pituitary gland.
Magnetization transfer (MT) techniques provide tissue contrast which depends mainly on the concentration of macromolecules. The magnetization transfer phenomenon is determined by the restricted macromolecular protons and is quantified by the magnetization transfer ratio (MTR). Since many macromolecular structures are implicated in the secretory activity of the pituitary gland, this imaging tech...
