Mesolimbic Functional Magnetic Resonance Imaging Activations during Reward Anticipation Correlate with Reward-Related Ventral Striatal Dopamine Release
- B. Schott, L. Minuzzi, +9 authors A. Bauer
- Psychology, Medicine
- The Journal of Neuroscience
- 24 December 2008
The dopaminergic mechanisms that control reward-motivated behavior are the subject of intense study, but it is yet unclear how, in humans, neural activity in mesolimbic reward-circuitry and its… Expand
O-(2-[18F]fluoroethyl)-L-tyrosine PET combined with MRI improves the diagnostic assessment of cerebral gliomas.
MRI is commonly used to determine the location and extent of cerebral gliomas. We investigated whether the diagnostic accuracy of MRI could be improved by the additional use of PET with the amino… Expand
Hemispheric Shape of European and Japanese Brains: 3-D MRI Analysis of Intersubject Variability, Ethnical, and Gender Differences
- K. Zilles, R. Kawashima, A. Dabringhaus, H. Fukuda, T. Schormann
- Psychology, Medicine
- 1 February 2001
Hemispheric shape is studied using magnetic resonance imaging and 3-D reconstructions in right-handed, male and female, European and Japanese subjects. Japanese hemispheres are relatively shorter,… Expand
A new method for fast quantitative mapping of absolute water content in vivo
We present a method for the localized and quantitative measurement of absolute water content based on the combination of two fast multi-slice and multi-time point sequences QUTE and TAPIR for mapping the T(2)* and T(1) relaxation times, respectively. Expand
Multimodal metabolic imaging of cerebral gliomas: positron emission tomography with [18F]fluoroethyl-L-tyrosine and magnetic resonance spectroscopy.
OBJECT The purpose of this study was to determine the predictive value of [18F]fluoroethyl-L-tyrosine (FET)-positron emission tomography (PET) and magnetic resonance (MR) spectroscopy for tumor… Expand
Statistics of deformations in histology and application to improved alignment with MRI
An exact registration of magnetic resonance images with histological sections is impeded by local deformations resulting from histological preparation procedures. Expand
Comparison of spatial normalization procedures and their impact on functional maps
- F. Crivello, T. Schormann, N. Tzourio-mazoyer, P. Roland, K. Zilles, B. Mazoyer
- Mathematics, Medicine
- Human brain mapping
- 1 August 2002
The alignment accuracy and impact on functional maps of four spatial normalization procedures have been compared using a set of high resolution brain MRIs and functional PET volumes acquired in 20… Expand
Comparison of fluorotyrosines and methionine uptake in F98 rat gliomas.
- K. Langen, M. Jarosch, +5 authors H. Coenen
- Chemistry, Medicine
- Nuclear medicine and biology
- 1 May 2003
The transport mechanisms of O-(2-[(18)F]fluoroethyl)-L-tyrosine (FET) and 2-[(18)F]fluoro-L-tyrosine (FTyr) were compared to those of [(3)H]-Methyl-L-methionine (MET) in F98 rat glioma cells in vitro… Expand
Fully-automated detection of cerebral water content changes: Study of age- and gender-related H2O patterns with quantitative MRI
We present a simple and robust method for the automated image analysis of quantitative cerebral water content maps acquired with MRI. Expand
Imaging of copper, zinc, and other elements in thin section of human brain samples (hippocampus) by laser ablation inductively coupled plasma mass spectrometry.
- J. Becker, M. Zoriy, C. Pickhardt, N. Palomero-Gallagher, K. Zilles
- Medicine, Chemistry
- Analytical chemistry
- 7 April 2005
Laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) was used to produce images of element distribution in 20-microm thin sections of human brain tissue. The sample surface was… Expand
