Significant decreases in [11C]ABP688 binding after a mismatch negativity paradigm - Brain PET Poster Sessions PP01-M01 to PP02-N07
BrainPET 2019, YokohamaYokohama, Japan, 4 Jul 2019 - 7 Jul 20192019-07-042019-07-07 () [10.1177/0271678X19851018]
The present work explores a novel estimation method based on a Markov-Chain Monte-Carlo (MCMC) sampling in a Bayesian context. This new methodology allows the integration of prior knowledge on parameters that constrain the available solutions, which alleviates the identifia-bility problem. [...]

RESampling between Projection SpACEs (RESPACE) using Bayse’ Theorem
2018 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC), SydneySydney, Australia, 10 Nov 2018 - 17 Nov 20182018-11-102018-11-17 [10.1109/NSSMIC.2018.8824431]
Abstract:In order to simplify the Point-Spread-Function (PSF) reconstruction framework, resolution modelling can be decoupled from the iterative reconstruction process by an additional data resampling step previous to reconstruction. We call the proposed algorithm RESampling between Projection spACEs (RESPACE). [...]

Attenuation Correction of Cerebellum in PET/MR Data
2017 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC), AtlantaAtlanta, GA, 21 Oct 2017 - 28 Oct 20172017-10-212017-10-28 [10.1109/NSSMIC.2017.8532870]
Abstract:Most approaches of modelling neuroreceptor PET studies apply the cerebellum as reference area. Therefore, it is mandatory that the respective attenuation correction (AC) method for reconstructing the emission data is most appropriate regarding cerebellar areas. [...]

Multimodal PET/MRI radiomics and clinical parameters for overall survival prediction in patients with IDH wildtype glioblastoma
60. Jahrestagung der Deutschen Gesellschaft für Nuklearmedizin, LeipzigLeipzig, Germany, 27 Apr 2022 - 30 Apr 20222022-04-272022-04-30 [10.1055/s-0042-1746120]
Ziel/Aim Currently, most radiomics studies on survival prediction in brain tumor patients are based on MRI only. The goal of our study was to evaluate multimodal radiomics derived from amino acid PET and MRI and clinical parameters for survival prediction in patients with newly diagnosed IDH wildtype glioblastoma.Methodik/Methods Sixty-three patients with newly diagnosed IDH wildtype glioblastoma were evaluated retrospectively.

Topological quantum materials have attracted enormous attention since their discovery due to the observedanomalous transport properties, which originate due to the non-zero Berry curvature. Mn3Ge has gainedspecial attention because of its large anomalous Hall and Nernst effects that persist starting from Néeltemperature (365 K) down to 2 K [1, 2]. [...]
