In spite of the hazard due to the radiation exposure, preparation of 90Y- and 177Lu-labelled radiopharmaceuticals is still mainly performed using manual procedures. In the present study the performance of a commercial automatic synthesizer based on disposable cassettes for the labelling of 177Lu- and 90Y-DOTA-conjugated biomolecules (namely, DOTATOC and PSMA-617) was evaluated and compared to a...
This prospective pilot study provides a dynamic whole body PET/MR image database, clinical safety, biodistribution profile and dosimetry of 68Ga-DOTATOC in healthy subjects, to establish a baseline and standard reference for its use in diagnosis and treatment response evaluation among patients with somatostatin receptor expressing neoplastic diseases. Dynamic whole body PET/MR imaging was perfo...
The aim of this study was to assess the efficacy of PRRT in patients with advanced neuroendocrine tumors (NETs). Patients and Methods. From January 2007 to August 2011, we enrolled 65 patients (m/f 38/27; mean age 65 years, range 33-83) with advanced NETs having enhanced SSTR expression, treated with PRRT. The enhanced expression of SSTR was assessed using (68)Ga-DOTATOC/DOTATATE PET/CT. Among ...
objective(s): gallium-68 dota-dphe1-tyr3-octreotide (68ga-dotatoc) has been applied by several european centers for the treatment of a variety of human malignancies. nevertheless, definitive dosimetric data are yet unavailable. according to the society of nuclear medicine and molecular imaging, researchers are investigating the safety and efficacy of this radiotracer to meet food and drug admin...
A 39 years old male patient with a history of an unresectable thymoma and synchronous liver metastases was referred tor our position. The patient had been originally treated with systemic chemotherapy followed by imatinib (Glivec) and sunitinib (Sutent). Since the therapeutic response was unsatisfactory, a gallium-68 ((68)Ga)-Dotatoc-positron emission tomography (PET) was performed and demonstr...
Abstract Introduction: Ectopic ACTH syndrome is rare but frequently a severe condition because of the intensity hypercortisolism. Patient management complex and demands both strategies: diagnosis treatment Cushing syndrome, specific neuroendocrine tumors. Therefore, should be performed ideally by experienced endocrinology teams in collaboration with surgeons, oncologists, nuclear medicine, spec...
UNLABELLED A novel radioguided surgery (RGS) technique for cerebral tumors using β(-) radiation is being developed. Checking for a radiotracer that can deliver a β(-) emitter to the tumor is a fundamental step in the deployment of such a technique. This paper reports a study of the uptake of (90)Y-DOTATOC in meningiomas and high-grade gliomas (HGGs) and a feasibility study of the RGS technique ...
AIMS Cardiac affection constitutes a major limiting condition in systemic sarcoidosis. The primary objective of this study was to investigate the persistence rate of cardiac sarcoid involvement by cardiovascular magnetic resonance (CMR) imaging in patients diagnosed with cardiac sarcoidosis (CS). Moreover, we examined the additional insights into myocardial damage's characteristics gained by so...
BACKGROUND The aim of this study was to assess the efficacy and safety of targeted radionuclide therapy with [90Y-DOTA0, Tyr3]-octreotide (90Y-DOTATOC) in patients with metastatic neuroendocrine tumors. PATIENTS AND METHODS One hundred and sixteen patients with metastatic neuroendocrine tumors were included. All patients were pre-therapeutically staged with morphological imaging procedures an...
