To take the effect into account that the relaxation length decreases with increasing slip, the longitudinal relaxation length [[sigma]*.sub.x] is calculated from the initial longitudinal relaxation length [[sigma].sub.x0], the slip stiffness [C.sub.[lambda]], the longitudinal force and the slip [lambda] [32]:
The longitudinal relaxation time (T1, ms) and transverse relaxation time (T2, ms) of the synthesized PEG contrast agent solutions were characterized by NMR measurements, and the T1-weight images were obtained by 1.5 T MRI.
In light of a recent report of Longitudinal Relaxation Enhancement (LRE) phenomena ex vivo [2], this study utilizes a similar technique to measure [T.sub.2] relaxation of selectively excited metabolites relevant to stroke in combination with high field MRS to investigate their potential to serve as stroke biomarkers.
