BACKGROUND With the increasing utilization of (68)Ge-(68)Ga radionuclide generators, (68)Ga labelled peptides like DOTATATE are receiving more attention in nuclear medicine. On the one hand, the long half-life of the parent nuclide (68)Ge is an enormous advantage for routine applications, but the question of the long-term stability of the (68)Ge breakthrough arises, which up to now has scarcely...
BACKGROUND Absorbed doses for α-emitters are different from those for β-emitters, as the high linear energy transfer (LET) nature of α-particles results in a very dense energy deposition over a relatively short path length near the point of emission. This highly localized and therefore high energy deposition can lead to enhanced cell-killing effects at absorbed doses that are non-lethal in low-...
BACKGROUND Glioblastoma multiforme (GBM) is the most common primary brain tumor in adults. Tumor-associated macrophages (TAM) have been shown to promote malignant growth and to correlate with poor prognosis. [1,4,7,10-tetraazacyclododecane-NN',N″,N'″-tetraacetic acid]-d-Phe1,Tyr3-octreotate (DOTATATE) labeled with Gallium-68 selectively binds to somatostatin receptor 2A (SSTR2A) which is specif...
Neuroendocrine tumor (NET) occurring in association with other endocrine syndromes forms a distinct entity. The aim was to assess the therapy response profile of the routine peptide receptor radionuclide therapy (PRRT) in this relatively uncommon but clinically challenging subgroup of patients. A retrospective analysis was undertaken from the case records from those who were treated with 177Lu-...
objective(s): gallium‐68 (ga‐68) is an ideal research and hospital‐based pet radioisotope. currently, the main form of ga‐68 radiopharmaceutical that is being synthesised in‐house is ga‐68 conjugated with dota based derivatives. the development of automated synthesis systems has increased the reliability, reproducibility and safety of radiopharmaceutical productions. here we report on our three...
INTRODUCTION The kidneys play an essential role in PRRT. The infusion of amino acids could reduce uptake in the kidney of radiolabelled peptides. The purpose of this study was to determine the extent of kidney damage post PRRT. MATERIAL AND METHODS 53 patients, with disseminated neuroendocrine tumours (NET), received 3-5 cycles of up to a maximum 7.4 GBq/m2 calculated dose of 90Y-DOTATATE (n ...
