Gustafsson J, Ljungberg M, Alm Carlsson G, Larsson E, Warfvinge C, Asp P, et al.
Med Phys
. 2023 Jun;
50(10):6600-6613.
PMID: 37272586
Background: Dosimetry in radionuclide therapy often requires the calculation of average absorbed doses within and between spatial regions, for example, for voxel-based dosimetry methods, for paired organs, or across multiple...

Okuda K, Nakajima K, Kitamura C, Ljungberg M, Hosoya T, Kirihara Y, et al.
J Nucl Cardiol
. 2023 Feb;
30(4):1630-1641.
PMID: 36740650
Purpose: We developed a method of standardizing the heart-to-mediastinal ratio in I-labeled meta-iodobenzylguanidine (MIBG) images using a conversion coefficient derived from a dedicated phantom. This study aimed to create a...

EJNMMI Phys
. 2022 May;
9(1):35.
PMID: 35526172
Background: Semiconductor gamma-camera systems based on cadmium zinc telluride (CZT) detectors present new challenges due to an energy-response that includes effects of low-energy tailing. In particular, such energy tails produce...

Kalaitzidis P, Gustafsson J, Hindorf C, Ljungberg M
Heliyon
. 2022 May;
8(4):e09316.
PMID: 35520630
The study aimed to create a pipeline from Monte Carlo simulated projections of a Gate PET system to reconstructed images. The PET system was modelled after the GE Discovery MI...

Sundlov A, Sjogreen Gleisner K, Tennvall J, Ljungberg M, Warfvinge C, Holgersson K, et al.
Eur J Nucl Med Mol Imaging
. 2022 Apr;
49(11):3830-3840.
PMID: 35451612
Purpose: Radionuclide therapy with Lu-DOTATATE is well established for patients with advanced somatostatin receptor-positive neuroendocrine tumors with a standard schedule of 7.4 GBq at four occasions. However, this approach does...

Morphis M, van Staden J, du Raan H, Ljungberg M
EJNMMI Phys
. 2021 Aug;
8(1):61.
PMID: 34410539
Purpose: The quantitative accuracy of Nuclear Medicine images, acquired for both planar and SPECT studies, is influenced by the isotope-collimator combination as well as image corrections incorporated in the iterative...

Tran-Gia J, Denis-Bacelar A, Ferreira K, Robinson A, Calvert N, Fenwick A, et al.
EJNMMI Phys
. 2021 Jul;
8(1):55.
PMID: 34297218
Purpose: Patient-specific dosimetry is required to ensure the safety of molecular radiotherapy and to predict response. Dosimetry involves several steps, the first of which is the determination of the activity...

Heliyon
. 2021 Jun;
7(6):e07196.
PMID: 34141944
Purpose: Monte Carlo (MC) modelling techniques can assess the quantitative accuracy of both planar and SPECT Nuclear Medicine images. It is essential to validate the MC code's capabilities in modelling...

Heliyon
. 2021 Mar;
7(2):e06097.
PMID: 33659726
Purpose: Monte Carlo (MC) modelling techniques have been used extensively in Nuclear Medicine (NM). The theoretical energy resolution relationship ( ), does not accurately predict the gamma camera detector response...
