Abstract Background PSMA-TO-1 (“Tumor-Optimized-1”) is a novel PSMA ligand with longer circulation time than PSMA-617. We compared the biodistribution in subcutaneous tumor-bearing mice of PSMA-TO-1, PSMA-617 and PSMA-11 when labeled with 68Ga an

Small-scale dosimetry for alpha particle 241Am source cell irradiation and estimation of γ-H2AX foci distribution in prostate cancer cell line PC3

Autor: Emma Mellhammar, Magnus Dahlbom, Oskar Vilhelmsson-Timmermand, Sven-Erik Strand

Publikováno v: EJNMMI Physics, Vol 9, Iss 1, Pp 1-20 (2022)

Abstract Background The development of new targeted alpha therapies motivates improving alpha particle dosimetry. For alpha particles, microscopic targets must be considered to estimate dosimetric quantities that can predict the biological response.

Publikováno v: EJNMMI Physics, Vol 8, Iss 1, Pp 1-13 (2021)

Abstract Background Regular and precise inspection of the realization of the local nuclear medicine standard operation procedures (SOPs) is very complex and time-consuming, especially when large amount of patient data is obtained from a wide scale of

Activity painting: PET images of freely defined activity distributions applying a novel phantom technique.

Autor: Attila Forgacs, Piroska Kallos-Balogh, Ferenc Nagy, Aron K Krizsan, Ildiko Garai, Lajos Tron, Magnus Dahlbom, Laszlo Balkay

Publikováno v: PLoS ONE, Vol 14, Iss 1, p e0207658 (2019)

The aim of this work was to develop a novel phantom that supports the construction of highly reproducible phantoms with arbitrary activity distributions for PET imaging. It could offer a methodology for answering questions related to texture measurem

A Study on the Basic Criteria for Selecting Heterogeneity Parameters of F18-FDG PET Images.

Autor: Attila Forgacs, Hermann Pall Jonsson, Magnus Dahlbom, Freddie Daver, Matthew D DiFranco, Gabor Opposits, Aron K Krizsan, Ildiko Garai, Johannes Czernin, Jozsef Varga, Lajos Tron, Laszlo Balkay

Publikováno v: PLoS ONE, Vol 11, Iss 10, p e0164113 (2016)

Textural analysis might give new insights into the quantitative characterization of metabolically active tumors. More than thirty textural parameters have been investigated in former F18-FDG studies already. The purpose of the paper is to declare bas

Automated movement correction for dynamic PET/CT images: evaluation with phantom and patient data.

Autor: Hu Ye, Koon-Pong Wong, Mirwais Wardak, Magnus Dahlbom, Vladimir Kepe, Jorge R Barrio, Linda D Nelson, Gary W Small, Sung-Cheng Huang

Publikováno v: PLoS ONE, Vol 9, Iss 8, p e103745 (2014)

Head movement during a dynamic brain PET/CT imaging results in mismatch between CT and dynamic PET images. It can cause artifacts in CT-based attenuation corrected PET images, thus affecting both the qualitative and quantitative aspects of the dynami
