Imaging cerebral tryptophan metabolism in brain tumor-associated depression
Springer Science and Business Media LLC - Tập 5 - Trang 1-9 - 2015
Edit Bosnyák, David O. Kamson, Michael E. Behen, Geoffrey R. Barger, Sandeep Mittal, Csaba Juhász
Depression in patients with brain tumors is associated with impaired quality of life and shorter survival. Altered metabolism of tryptophan to serotonin and kynurenine metabolites may play a role in tumor-associated depression. Our recent studies with alpha[11C]methyl-L-tryptophan (AMT)-PET in brain tumor patients indicated abnormal tryptophan metabolism not only in the tumor mass but also in norm...... hiện toàn bộ
Feasibility of equivalent performance of 3D TOF [18F]-FDG PET/CT with reduced acquisition time using clinical and semiquantitative parameters
Springer Science and Business Media LLC - Tập 11 - Trang 1-11 - 2021
Julia Pilz, Lukas Hehenwarter, Georg Zimmermann, Gundula Rendl, Gregor Schweighofer-Zwink, Mohsen Beheshti, Christian Pirich
High-performance time-of-flight (TOF) positron emission tomography (PET) systems have the capability for rapid data acquisition while preserving diagnostic image quality. However, determining a reliable and clinically applicable cut-off of the acquisition time plays an important role in routine practice. This study aimed to assess the diagnostic equivalence of short acquisition time of 57 with rou...... hiện toàn bộ
Syndecan-1 antigen, a promising new target for triple-negative breast cancer immuno-PET and radioimmunotherapy. A preclinical study on MDA-MB-468 xenograft tumors
Springer Science and Business Media LLC - - 2011

Abstract Background Overexpression of syndecan-1 (CD138) in breast carcinoma correlates with a poor prognosis and an aggressive phenotype. The objective of this study was to evaluate the potential of targeting CD138 by immuno-PET imaging and radioimmunotherapy (RIT) using the antihuman syndecan-1...... hiện toàn bộ
Quantitative and clinical impact of MRI-based attenuation correction methods in [18F]FDG evaluation of dementia
Springer Science and Business Media LLC - Tập 9 - Trang 1-12 - 2019
Silje Kjærnes Øen, Thomas Morten Keil, Erik Magnus Berntsen, Joel Fredrik Aanerud, Thomas Schwarzlmüller, Claes Nøhr Ladefoged, Anna Maria Karlberg, Live Eikenes
Positron emission tomography/magnetic resonance imaging (PET/MRI) is a promising diagnostic imaging tool for the diagnosis of dementia, as PET can add complementary information to the routine imaging examination with MRI. The purpose of this study was to evaluate the influence of MRI-based attenuation correction (MRAC) on diagnostic assessment of dementia with [18F]FDG PET. Quantitative difference...... hiện toàn bộ
99mTc-HYNIC-IL-2 scintigraphy to detect acute rejection in lung transplantation patients: a proof-of-concept study

A guideline proposal for mice preparation and care in 18F-FDG PET imaging
Springer Science and Business Media LLC - Tập 12 - Trang 1-9 - 2022
F. M. Ribeiro, P. M. M. Correia, A. C. Santos, J. F. C. A. Veloso
The experimental outcomes of small-animal positron emission tomography (PET) imaging with 18F-labelled fluorodeoxyglucose (18F-FDG) can be particularly compromised by animal preparation and care. Several works intend to improve research reporting and amplify the quality and reliability of published research. Though these works provide valuable information to plan and conduct animal studies, manusc...... hiện toàn bộ
Long-term Ashtanga yoga practice decreases medial temporal and brainstem glucose metabolism in relation to years of experience
Springer Science and Business Media LLC - Tập 10 - Trang 1-8 - 2020
June van Aalst, Jenny Ceccarini, Georg Schramm, Donatienne Van Weehaeghe, Ahmadreza Rezaei, Koen Demyttenaere, Stefan Sunaert, Koen Van Laere
Yoga is increasingly popular worldwide with several physical and mental benefits, but the underlying neurobiology remains unclear. Whereas many studies have focused on pure meditational aspects, the triad of yoga includes meditation, postures, and breathing. We conducted a cross-sectional study comparing experienced yoga practitioners to yoga-naive healthy subjects using a multiparametric 2 × 2 de...... hiện toàn bộ
18F-fluoride-PET for dynamic in vivo monitoring of bone formation in multiple myeloma

Anti PD-1 treatment increases [18F]FDG uptake by cancer cells in a mouse B16F10 melanoma model
Springer Science and Business Media LLC - Tập 8 - Trang 1-8 - 2018
Mayu Tomita, Hironobu Yasui, Kei Higashikawa, Kohei Nakajima, Hideo Takakura, Tohru Shiga, Yuji Kuge, Mikako Ogawa
Programmed cell death 1 (PD-1) inhibitors act as immune checkpoint inhibitors and are more effective for improving survival time with less toxicity as compared with conventional chemotherapies. In anti PD-1 therapy, it is important to evaluate metabolism in the cancer microenvironment, as this helps to clarify the pathological conditions. Herein, we investigate the early effects of PD-1 therapy on...... hiện toàn bộ
Characteristics of immunoglobulin G4-related aortitis/periaortitis and periarteritis on fluorodeoxyglucose positron emission tomography/computed tomography co-registered with contrast-enhanced computed tomography
Springer Science and Business Media LLC - Tập 7 - Trang 1-9 - 2017

We aimed to assess the positivity, distribution, quantitative degree of vessel inflammation, and clinical characteristics of IgG4-related aortitis/periarteritis and periarteritis (IgG4-aortitis), and to examine the difference in these characteristics between cases with and without IgG4-aortitis, using fluorodeoxyglucose positron-emission tomography/computed tomography (FDG-PET/CT) co-registered wi...... hiện toàn bộ
