… RF R(t), we derive universal two-sided estimates for the RF by means of RC shifts (1.5),
and several variants of the methods for determining the relaxation function of the CE (1.1) with …

… with very different time constants, the estimation of T, or T2 is … relaxation, the estimation of
time constants is a nontrivial problem. Nevertheless, the quantitative interpretation of NMR relax…

… In this paper, we have proposed a new way to estimate T 1 relaxation times retroactively
that only requires the acquisition of four or fewer conventional MR images. The “QuEEN maps” …

Magnetic resonance (MR) relaxation time constants T1 and T2 were estimated in frontal and …
estimates were obtained with 0.02-T and 0.8-MHz MR imaging. T1 values were estimated …

… All curve fitting was performed with Kaleidagraph software (Abelbeck Software, Reading,
Pa). Estimates of T1 and T2 relaxation times were obtained from the nonlinear least square fit …

… Different approaches can be applied in order to evaluate the relaxation coefficient from
the decay curve, such as mono-exponential fit for highly homogeneous samples, or for …

… determined by both the MUNIN-based and the conventional approach, yielding relaxation
times and their errors. The uncertainties in T 1 values were in all cases carefully estimated by …

… between the τ estimates from both methods and to decide for the more reliable estimate. The
effect of presetting a zero asymptote on the τ estimate was investigated mathematically and …

… Monte Carlo simulations of proton random walks have been used by several groups to
estimate transverse relaxation enhancement caused by diffusion through inhomogeneous …

… We have measured the relaxation times of protons in paramagnetic solutions containing …
The estimated error in these times is about 20 percent. These results show a ratio o/p= —', . …
