Comparison of the dosimetry of scandium-43 and scandium-44 patient organ doses in relation to commonly used gallium-68 for imaging neuroendocrine tumours [PDF]

EJNMMI Physics
Background Several research groups have explored the potential of scandium radionuclides for theragnostic applications due to their longer half-lives and equal or similar coordination chemistry between their diagnostic and therapeutic counterparts, as ...

Folate-Based Radiotracers for PET Imaging—Update and Perspectives

Molecules, 2013
The folate receptor (FR) is expressed in many tumor types, among those ovarian and lung cancer. Due to the high FR affinity of folic acid, it has been used for targeting of FR-positive tumors, allowing specific delivery of attached probes to the ...

Assessing the influence of prostate tissue traits on Gallium-68 prostate-specific membrane-antigen positron-emission tomography/computed tomography: predictive factors for image positivity and locoregional recurrence in prostate cancer patients treated with radical prostatectomy and without prior or salvage treatment

Prostate International
Background: Gallium-68 prostate-specific membrane-antigen positron emission tomography/computed tomography (68Ga-PSMA-11 PET/CT) has recently emerged as a novel imaging modality, potentially improving oncologic outcomes for prostate cancer patients. This

Chemical radioanalysis of production of positron-emitting radioisotope Gallium-68 via (p,n) and (p,2n) reactions using compact cyclotron for tomography applications

Heliyon
In this study, the proton-induced reactions of 68Zn and 69Ga aimed at generating 68Ga were simulated and modeled using Talys code and neural network software. In the first step, both targets were simulated under different proton energies and at different bombardments times to generate a total of six thousand data. Then, the obtained data from the Talys,
