The diagnosis is conducted for the prediction of the efficacy of specific therapeutic interventions on an individual basis as well as for treatment response monitoring. One more important aspect is pre-therapeutic individual dosimetry for the assessment of potential radiotoxicity to the essential Selleckchem Birinapant radiosensitive organs, such as bone marrow, organs with a physiological uptake of the radiopharmaceutical and healthy tissue surrounding lesions and excretory organs. Dosimetry evaluates the distribution and kinetics of an administered radiopharmaceutical [3]. In the case of peptide based agents, the kidney is often a limiting organ and the maximal tolerated absorbed dose must be determined for each individual patient. Thereby the optimal radiotherapeutic dose can be determined Megestrol Acetate and undertreatment as well as nephrotoxicity can be avoided. 177Lu-labelled somatostatin analogues have been used for peptide receptor radionuclide therapy (PRRT) of tumours overexpressing somatostatin receptors (SSTRs) such as neuroendocrine tumours resulting in symptomatic improvement without any severe side effects [4,5]. The maximum beta particle (E(��-) = 0.497 MeV; 78.7%) range in tissue is 2 mm for 177Lu and the common perception has been that the short range was relevant for the smaller tumours. However, it has been demonstrated that even 177Lu can be efficient for the treatment of larger tumours [6]. In particular, the effectiveness of 177Lu in treatment of neuroendocrine tumours and its favourable dosimetry in kidneys compared to 90Y is well documented [4,7,8]. Renal protection using lysine and Gemcitabine clinical trial arginine amino acid solutions is often required. The bone marrow is also an organ at risk. 177Lu emits also gamma radiation that can be used for the simultaneous with PRRT SPECT imaging and dosimetry. However, the accurate assessment of the therapy response might require more sensitive and quantitative technique such as 68Ga/PET-CT. Insulinomas are clinically characterized by severe symptoms of hyperinsulinism due to unregulated insulin secretion and consequently hypoglycaemia. It is a rare but potentially fatal disease. After the biochemical diagnosis, lesion localization and staging are of paramount importance for adequate patient management. Insulinomas are usually benign and curative surgery is the gold standard treatment if the lesions can be localized. However, with surgery there is always risk for complications and it might not be an option for metastasized insulinomas [9,10]. Due to the small size of the tumours (82%
