Comprehensive SPECT/CT system characterization and calibration for 177Lu quantitative SPECT (QSPECT) with dead-time correction
EJNMMI Physics - Tập 7 - Trang 1-22 - 2020
Andrea Frezza, Corentin Desport, Carlos Uribe, Wei Zhao, Anna Celler, Philippe Després, Jean-Mathieu Beauregard
Personalization of 177Lu-based radionuclide therapy requires implementation of dosimetry methods that are both accurate and practical enough for routine clinical use. Quantitative single-photon emission computed tomography/computed tomography (QSPECT/CT) is the preferred scanning modality to achieve this and necessitates characterizing the response of the camera, and calibrating it, over the full ...... hiện toàn bộ

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
Distortion correction of MR data in whole-body small animal PET-MR using 3D thin-plate splines
EJNMMI Physics - Tập 1 - Trang 1-2 - 2014

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
Impact of segmentation and discretization on radiomic features in 68Ga-DOTA-TOC PET/CT images of neuroendocrine tumor
EJNMMI Physics - Tập 8 - Trang 1-21 - 2021
Virginia Liberini, Bruno De Santi, Osvaldo Rampado, Elena Gallio, Beatrice Dionisi, Francesco Ceci, Giulia Polverari, Philippe Thuillier, Filippo Molinari, Désirée Deandreis
To identify the impact of segmentation methods and intensity discretization on radiomic features (RFs) extraction from 68Ga-DOTA-TOC PET images in patients with neuroendocrine tumors. Forty-nine patients were retrospectively analyzed. Tumor contouring was performed manually by four different operators and with a semi-automatic edge-based segmentation (SAEB) algorithm. Three SUVmax fixed thresholds...... hiện toàn bộ
Quantitative validation of Monte Carlo SPECT simulation: application to a Mediso AnyScan GATE simulation
EJNMMI Physics - Tập 10 - Trang 1-25 - 2023
Sophia Pells, David M. Cullen, Daniel Deidda, Ana M. Denis-Bacelar, Andrew Fenwick, Kelley M. Ferreira, David Hamilton, Warda Heetun, Peter Julyan, George Needham, Ben Pietras, Emlyn Price, James Scuffham, Jill Tipping, Andrew P. Robinson
Monte Carlo (MC) simulations are used in nuclear medicine imaging as they provide unparalleled insight into processes that are not directly experimentally measurable, such as scatter and attenuation in an acquisition. Whilst MC is often used to provide a ‘ground-truth’, this is only the case if the simulation is fully validated against experimental data. This work presents a quantitative validatio...... hiện toàn bộ
