White matter lesions are a common finding on T2- and FLAIR-weighted MRI scans of older subjects, but their etiology and relationship to cognitive
function remains unclear. The aim of this pilot study was to characterize differences in magnetization transfer ratio and spin-lattice relaxation time between
macroscopically normal-appearing white matter and white matter lesions in a subset of a unique cohort of aging subjects, the Lothian Birth Cohort 1936.

The present study bridges the gap between midlife hypertension and late-life cognitive impairment, a relationship that has long been documented but remains
poorly understood. We demonstrate that midlife hypertension and associated arterial thickening relate to cerebral measures of neuronal health and viability
in middle-aged adults with intact cognitive performance.

With menopause, women underwent changes of overall hormones, leading to functional changes of organs. A majority of menopausal women experience
some exchanges in sexual function. Using fMRI technique, menopausal a few papers concerning differential brain activation patterns between
premenopausal and menopausal women were published. However, it is unclear how brain metabolite change in menopause affects sexual arousal.
The purpose of this study was to investigate the brain metabolic changes associated with visual sexual arousal in premenopausal and menopausal women
using functional MR spectroscopy (fMRS).
2007. Motion Detection in Healthy Young, Middle-Aged, and Elderly Adults Using a Water Signal Based

Here, we build upon our earlier work incorporating a CHESS pulse into a STEAM sequence by presenting a new method for analyzing and interpreting
motion data collected from three age groups: healthy young (HY), healthy middle-aged (HM), and healthy elderly (HE). Our results show that listed in
increasing order of motion during a 1 H MRS STEAM spectroscopy examination: HY, HM, and HE.

Quantitative assessment of 1 H-MRS metabolite concentrations has the potential to be an in-vivo marker for disease progression and treatment efficacy in
pharmaceutical trials. The present study examines cross-site reproducibility of 1 H-MRS metabolite concentrations measured on the same 5 people at 6 sites.
Average percent differences of inter and intra-site reproducibility was
