SPECT image segmentation for estimation of tumour volume and activity concentration in 177Lu-DOTATATE radionuclide therapy
BACKGROUND Dosimetry in radionuclide therapy has the potential to allow for a treatment tailored to the individual patient. One therapeutic radiopharmaceutical where patient-specific dosimetry is feasible is 177Lu-DOTATATE, used for the treatment of neuroendocrine tumours. The emission of gamma photons by 177Lu allows for imaging with SPECT (single photon emission computed tomography). One impo...
متن کاملAccuracy and precision assessment for activity quantification in individualized dosimetry of 177Lu-DOTATATE therapy
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...
متن کاملDose response of pancreatic neuroendocrine tumors treated with peptide receptor radionuclide therapy using 177Lu-DOTATATE.
UNLABELLED Peptide receptor radionuclide therapy (PRRT) is a promising treatment for patients with neuroendocrine tumors, giving rise to improved survival. Dosimetric calculations in relation to PRRT have been concentrated to normal organ dosimetry in order to limit side effects. However, the relation between the absorbed dose to the tumor and treatment response has so far not been established....
متن کاملNephrotoxicity after PRRT - still a serious clinical problem? Renal toxicity after peptide receptor radionuclide therapy with 90Y-DOTATATE and 90Y/177Lu-DOTATATE.
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 ...
متن کاملMethod dependence, observer variability and kidney volumes in radiation dosimetry of 177Lu-DOTATATE therapy in patients with neuroendocrine tumours
BACKGROUND Radionuclide therapy can be individualized by performing dosimetry. To determine absorbed organ doses in (177)Lu-DOTATATE therapy, three methods based on activity concentrations are currently in use: the small volume of interest (sVOI) method, and two methods based on large VOIs either on anatomical CT (aVOI) or on thresholds on functional images (tVOI). The main aim of the present w...
