BACKGROUND In order to obtain a reliable 177Lu-DOTATATE therapy dosimetry, it is crucial to acquire accurate and precise activity measurements with the radionuclide calibrator, the SPECT/CT camera, and the NaI(Tl) well counter. The aim of this study was to determine, in a clinical context, the accuracy and the precision of their activity quantification over a range of activities and time. Ninet...
Peptide receptor radionuclide therapy (PRRT), developed over the last two decades, is carried out using radiopharmaceuticals such as 90Y-DOTA-Tyr3-octreotide and 177Lu-DOTA-Tyr3-octreotate (177Lu-Dotatate). These radiocompounds are obtained by labeling a synthetic somatostatin analog with a β-emitting radioisotope. The compounds differ from each other in terms of their energetic features (due t...
OBJECTIVES Lutetium-177 can be made with high specific activity and with no other isotopes of lutetium present, referred to as "No Carrier Added" (NCA) 177Lu. We have radiolabelled DOTA-conjugated peptide DOTA-(Tyr3)-octreotate with NCA 177Lu ("NCA-LuTATE") and used it in nearly 40 therapeutic administrations for subjects with neuroendocrine tumours or meningiomas. In this paper, we report on o...
Fifteen dogs were referred because of a spontaneous bone tumor, lameness, and local pain. The osteosarcoma diagnosis was established by clinical examination, X-ray, bone scintigraphy, and histological examination of biopsy material. The tumors were located in the extremities (n = 12), scapula (n = 1), maxilla (n = 1), and the frontal bone (n = 1). The dogs were given one to four i.v. injections...
BACKGROUND Radiation-induced nephropathy is still dose limiting in radionuclide therapy of neuroendocrine tumors. We investigated the nephroprotective potential of the angiotensine converting enzyme inhibiting drug enalpril after [177Lu]-DOTATATE therapy in a murine model of radiation-induced nephropathy by renal scintigraphy. At first, the appropriate therapy activity to induce nephropathy was...
177Lu-labeled PSMA-617 is a promising new therapeutic agent for radioligand therapy (RLT) of patients with metastatic castration-resistant prostate cancer (mCRPC). Initiated by the German Society of Nuclear Medicine, a retrospective multicenter data analysis was started in 2015 to evaluate efficacy and safety of 177Lu-PSMA-617 in a large cohort of patients. METHODS One hundred forty-five pati...
introduction: rheumatoid arthritis (ra) is the most common autoimmune disease, leading to the destruction of the joints and causing pain, disability, and immobility in the patients. radiosynovectomy (rsv) has been applied as an effective treatment for the patients with resistant synovitis after failure of long-term pharmacotherapy and intra-articular steroid injection for more than 50 years. se...
Coastal bermudagrass hay was labeled with Cr by the Cr-mordant procedure and with 177Lu applied to the same fiber. Neutral detergent fiber prepared from the same Coastal bermudagrass hay was labeled with Yb, 169Yb, Tb and 160Tb by soaking overnight following by thorough washing and drying. Wood chips were similarly labeled with Sm or La, and Solka Floc was labeled with 147Nd and 141Ce. The carr...
UNLABELLED The aim of this study was to introduce a new quantification method for 153Sm-ethylenediaminetetramethylenephosphonate (EDTMP) and 186Re-(tin)1,1-hydroxyethylidene diphosphonate (HEDP) to separately measure bone uptake and soft-tissue retention of these radiopharmaceuticals. METHODS Studies were performed on 23 men and 6 women undergoing radionuclide therapy for palliation of bone p...
PURPOSE Computational simulation is a simple and practical way to study and to compare a variety of radioisotopes for different medical applications, including the palliative treatment of bone metastases. This study aimed to evaluate and compare cellular effects modelled for different radioisotopes currently in use or under research for treatment of bone metastases using computational methods. ...
