Journal ArticleDOI
Combining MRI and MRS to distinguish between Alzheimer's disease and healthy controls.

TL;DR: Adding MRS measures to a multivariate analysis of MRI measures resulted in significantly better classification than using MRI measures alone, and the OPLS method shows strong potential for discriminating between AD and controls.
Journal ArticleDOI

TL;DR: The findings suggest that the strongest neuroanatomic effect of APOE ɛ4 on the hippocampus is observed in AD and groups most at risk of developing the disease, whereas hippocampi of old and young healthy individuals remain unaffected.
Journal Article
Effects of three different doses of a bolus injection of gadodiamide: assessment of regional cerebral blood volume maps in a blinded reader study.
Roland Bruening,Christian Berchtenbreiter,Nicolaus Holzknecht,Marco Essig,Ren Hua Wu,Andrew Simmons,Andreas Heuck,Anne Maschek,Monika Meusel,Steve C.R. Williams,Tim C. S. Cox,Michael V. Knopp,Maximilian F. Reiser +12 more
TL;DR: A dose of 0.2 mmol/kg of gadodiamide is recommended for reconstruction of rCBV maps if data are acquired with the T2*-weighted protocol described.
Journal ArticleDOI
Effects of estrogen therapy on age-related differences in gray matter concentration.
David J. Robertson,Michael C. Craig,T. van Amelsvoort,Eileen Daly,C J Moore,Andrew Simmons,Malcolm Whitehead,Robin G. Morris,Declan G. Murphy +8 more
TL;DR: In this article, the long-term effects of estrogen therapy (ET) on the structural integrity of neural tissue in postmenopausal women were investigated using magnetic resonance imaging and voxel-based morphometry.
Journal ArticleDOI
The functional anatomy of the McCollough contingent colour after-effect.
TL;DR: Data confirm the critical role of the fusiform gyrus in actual and illusory colour perception as well as revealing localized frontal cortical activation associated with the ME, which would suggest that a 'top-down' mechanism is implicated in this illusion.
