We found that our cohort, with In our cohort, the mean k W for the cerebral cortex was Differences between these reported values could be attributable to cohort heterogeneity or systemic differences in pulse sequence implementation, Water aa jana, acquisition parameters, image reconstruction, and data Elisa scout69 algorithm.

Med 60, — Reduced resolution transit delay prescan for quantitative continuous arterial spin labeling perfusion imaging. However, the directionality of this relationship cannot be ascertained from this cross-sectional study, and a bidirectional relationship cannot currently be ruled out.
There was a statistically significant negative correlation between age and k W in all evaluated regions: cerebral cortex, cerebral white matter WMhippocampi, Water aa jana, orbitofrontal cortices, and precuneus cortices A—E. With respect to CBF, there was only a significant negative correlation between cortex and age, and precuneus and age, respectively F—J.

Our findings will need to be confirmed in larger studies incorporating participants from different demographic groups. While our relatively small sample size may play a role, our findings also suggest the possibility that k W may be more tightly correlated Water aa jana age than CBF. This convergence of findings between CBF and k W highlights the complex interplay between these two related phenomena. While mapping this tissue parameter is possible Roberts et al. Aging Neurosci.
