- Influence of the resolution mode on mean and maximum SUV for PET images acquired by a LabPET SOLO 4 scanner J. V. C. Barbosa G. C. A. Souza R. M. G. Gontijo B. M. Mendes A. V. Ferreira Biología LabPET SOLO 4 Resolution Mode Standardized Uptake Value In preclinical PET, SUV (standardized uptake value) is a robust quantifier that can be used to analyze PET images. Several factors – biological or technical – can affect SUV determination. Among technical factors, it is possible to cite the reconstruction protocols of PET images. This work evaluated the influence of two resolution modes – standard and high – on mean and maximum SUVs. The PET image of a mouse with a tumor in left flank was chosen from a PET image bank and reconstructed using two different protocols varying the resolution mode. The post-processing of images was performed using AMIDE software and eight volumes of interest (VOIs) were defined. Qualitatively, there was light improvement in structures definition in high-resolution image compared to standard resolution image. At the semiquantitative analysis, image reconstruction protocols using high-resolution mode did not significantly improve the recuperation of radiopharmaceutical uptake into analyzed tissues. 2023 artículo científico 2319-0612 https://www.redalyc.org/articulo.oa?id=722277920004 https://www.redalyc.org/journal/7222/722277920004/ https://www.redalyc.org/journal/7222/722277920004/html/ https://www.redalyc.org/journal/7222/722277920004/722277920004.epub https://www.redalyc.org/journal/7222/722277920004/movil https://doi.org/10.15392/2319-0612.2023.2273 en http://www.redalyc.org/revista.oa?id=7222 Brazilian Journal of Radiation Sciences application/pdf Sociedade Brasileira de Proteção Radiológica - SBPR Brazilian Journal of Radiation Sciences (Brasil) Num.3 Vol.11
