Our goal was to characterize pathological tissues of liver by magnetic resonance (MR)-related parameters such as T1 and magnetization transfer (MT) indices and to evaluate the clinical efficacy of MT contrast (C) in diagnosis of liver diseases via bi

In spin-lattice relaxation time measurements, the relaxation time T1 is estimated from measuring the longitudinal magnetization during its return to thermal equilibrium from an initial (nonequilibrium) state. T1 estimation error depends on a number o

The role of water of hydration in proton relaxation in tissues as exemplified by hydrated collagen in beef tendon was studied as a function of temperature from -40 degrees to 37 degrees C by using cross-relaxation spectroscopy. Experimental data were

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 evalu
