Image quality assessment along the one metre axial field-of-view of the total-body Biograph Vision Quadra PET/CT system for 18F-FDG
EJNMMI Physics - Tập 9 - Trang 1-17 - 2022
Ivo Rausch, Julia G. Mannheim, Jürgen Kupferschläger, Christian la Fougère, Fabian P. Schmidt
Recently, total-body PET/CT systems with an extended axial field-of-view (aFOV) became commercially available which allow acquiring physiologic information of multiple organs simultaneously. However, the nominal aFOV may clinically not be used effectively due to the inherently reduced sensitivity at the distal ends of the aFOV. The aim of this study was to assess the extent of the useful aFOV of t...... hiện toàn bộ

Abstract Background This study evaluated the physical performance of a positron emission tomography (PET) system dedicated to the head and breast according to the National Electrical Manufacturers Association (NEMA) NU2-2012 standard. ... hiện toàn bộ
Feasibility of PET/CT system performance harmonisation for quantitative multicentre 89Zr studies
EJNMMI Physics - Tập 5 - Trang 1-8 - 2018
Andres Kaalep, Marc Huisman, Terez Sera, Danielle Vugts, Ronald Boellaard
The aim of this study was to investigate the variability in quantitative performance and feasibility of quantitative harmonisation in 89Zr PET/CT imaging. Eight EANM EARL-accredited (Kaalep A et al., Eur J Nucl Med Mol Imaging 45:412–22, 2018) PET/CT systems were investigated using phantom acquisitions of uniform and NEMA NU2-2007 body phantoms. The phantoms were filled according to EANM EARL guid...... hiện toàn bộ
Human biodistribution and dosimetry of [11C]-UCB-J, a PET radiotracer for imaging synaptic density
EJNMMI Physics - - 2021
Christopher Cawthorne, Paul Maguire, Joel Mercier, David Sciberras, Kim Serdons, Guy Bormans, Jan de Hoon, Koen Van Laere, Michel Koole
[11C]-UCB-J is an emerging tool for the noninvasive measurement of synaptic vesicle density in vivo. Here, we report human biodistribution and dosimetry estimates derived from sequential whole-body PET using two versions of the OLINDA dosimetry program. Sequential whole-body PET scans were performed in 3 healthy subjects for 2 h after injection of 254 ± 77 MBq [11C]-UCB-J. Volumes of interest were...... hiện toàn bộ
Cardiac PET/CT with Rb-82: optimization of image acquisition and reconstruction parameters
EJNMMI Physics - Tập 4 - Trang 1-15 - 2017
P. Chilra, S. Gnesin, G. Allenbach, M. Monteiro, J. O. Prior, L. Vieira, J. A. Pires Jorge
Our aim was to characterize the influence of time-of-flight (TOF) and point spread function (PSF) recovery corrections, as well as ordered subset expectation maximization (OSEM) reconstruction parameters, in 82Rb PET/CT quantification of myocardial blood flow (MBF) and myocardial flow reserve (MFR). Rest and stress list-mode dynamic 82Rb PET acquisition data from 10 patients without myocardial flo...... hiện toàn bộ
Combined quality and dose-volume histograms for assessing the predictive value of 99mTc-MAA SPECT/CT simulation for personalizing radioembolization treatment in liver metastatic colorectal cancer
EJNMMI Physics - Tập 7 - Trang 1-19 - 2020
Hugo Levillain, Manuela Burghelea, Ivan Duran Derijckere, Thomas Guiot, Akos Gulyban, Bruno Vanderlinden, Michael Vouche, Patrick Flamen, Nick Reynaert
The relationship between the mean absorbed dose delivered to the tumour and the outcome in liver metastases from colorectal cancer patients treated with radioembolization has already been presented in several studies. The optimization of the personalized therapeutic activity to be administered is still an open challenge. In this context, how well the 99mTc-MAA SPECT/CT predicts the absorbed dose d...... hiện toàn bộ
Tumor dosimetry using 177Lu: influence of background activity, measurement method and reconstruction algorithm
EJNMMI Physics - Tập 10 Số 1
Peter Staanum
Abstract Background Image-based tumor dosimetry after radionuclide therapy, using the isotope 177Lu, finds application e.g., for tumor-to-organ dose comparison and for dose response evaluation. When the tumor extent is not much larger than the image resolution, and when ... hiện toàn bộ
