Quantitative diffusion tensor fiber tracking of age-related changes in the limbic system.
Stadlbauer A, Salomonowitz E, Strunk G, Hammen T, Ganslandt O. Stadlbauer A, et al. Eur Radiol. 2008 Jan;18(1):130-7. doi: 10.1007/s00330-007-0733-8. Epub 2007 Aug 15. Eur Radiol. 2008. PMID: 17701181
Thirty-eight healthy subjects aged 18-88 years were examined at 3 Tesla using a 1.9-mm isotropic DTI sequence. Quantitative fiber tracking was performed for 3D-segmentation of the fornix and the cingulum to determine fractional anisotropy (FA), mean diffusivity (MD), eigen …
