Effect of image registration on 3D absorbed dose calculations in 177Lu-DOTATOC peptide receptor radionuclide therapy.
Peptide receptor radionuclide therapy (PRRT) is an effective MRT (molecular radiotherapy) treatment, which consists of multiple administrations of a radiopharmaceutical labelled with 177Lu or 90Y. Through sequential functional imaging a patient specific 3D dosimetry can be derived. Multiple scans should be previously co-registered to allow accurate absorbed dose calculations. The purpose of thi...
متن کاملThe comparison of serial SPECT-CT imaging to estimate absorbed dose to the organ at risk from peptide receptor radionuclide therapy dosimetry
Introduction: In Peptide Receptor Radionuclide Therapy (PRRT), the administration of radionuclide such as Lu-177 label with a pharmaceutical agent useful to destroy the lesion. The amount of Lu-177 radioactivity administered to the patients is still not standardize and generally not more than 7.4 GBq per session due to the patient’s safety issues. The first cycle of Lu-177 is a...
متن کاملPeptide receptor radionuclide therapy.
On their plasma membranes, cells express receptor proteins with high affinity for regulatory peptides, such as somatostatin. Changes in the density of these receptors during disease, for example, overexpression in many tumors, provide the basis for new imaging methods. The first peptide analogues successfully applied for visualization of receptor-positive tumors were radiolabeled somatostatin a...
متن کاملTargeted radionuclide therapy with 90Y-DOTATOC in patients with neuroendocrine tumors.
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...
متن کاملBiokinetic and Dosimetry of 90y-dotatoc Therapy for Neuroendocrine Tumours
Biokinetic model is a mathematical model which describes the behavior of the Y in human body during the treatment of neuroendocrine tumours. This paper presents calculation of absorbed doses in human organs in biokinetic model Y for DOTATOC therapy. For this purpose, the human body is represented by five compartments: blood, kidneys, urinary bladder, tumour and liver. The input file was develop...
