摘要
Background: This study investigates how T-1-weighted MRI can be used to evaluate brain anatomical changes. We investigated these changes in Alzheimer's disease (AD) and normal aging. Methods: A semiquantitative brain atrophy and lesion index (BALI) was constructed by adapting existing visual rating scales and validated in 3 datasets. Results: The T-1- and T-2-weighted-imaging-based scores were highly correlated. They were both closely associated with age and with cognitive test scores. Conclusion: The T-1-based BALI helps describe brain structural variability in AD, mild cognitive impairment and normal aging. Copyright (C) 2010 S. Karger AG, Basel
