Proton spin-lattice, T I , and spin-spin, Tz, relaxation times of uniaxially stretched polypropylene film were measured at 40°C using a wide line pulse spectrometer operating at 19.8 MHz. T11, the longer T I , increases almost linearly with increasing stretching ratio, and Tza, Tz of the amorphous r

The magnetic field dependence of the water-proton spin-lattice relaxation rate (1/T(1)) in tissues results from magnetic coupling to the protons of the rotationally immobilized components of the tissue. As a consequence, the magnetic field dependence of the water-proton (1/T(1)) is a scaled report o
Calculation of tissue TI in double spin-echo imaging (90"-T-I 80"-2T-1 SO0) using two repetition times (6, and b2) has entailed an approximation that ignores the two 180" pulses. The theoretical consequence of the simplification is to overestimate TI with a fractional error that increases with incre
The goal of this work is to provide regional T(1) and T(2) values at a field strength of 7 T for the normal mouse brain at 6 weeks and 1 year old. A novel segmented snapshot FLASH sequence was used to measure T(1) in the hippocampus, corpus callosum, and the retrosplenial granular (RSG) cortex; T(2)
## Abstract __T__~1~ and __T__~2~ can be rapidly determined with a combination of multiangle spoiled gradient recalled echo (SPGR) and steady‐state free precession (SSFP) imaging. Previously, we demonstrated a simple method for determining the set of SPGR and SSFP angles that provided greater __T__
1H NMR spin-lattice relaxation times (T1) of the N-CH3 proton resonances of phosphocreatine (PCr) and creatine (Cr) in water solutions were obtained using the 1,3,3,1 pulse sequence. These T1 values were equivalent to those obtained in D2O and water using either the conventional inversion-recovery e
