Semi-automatic 3D-volumetry of liver metastases from neuroendocrine tumors to improve combination therapy with 177Lu-DOTATOC and 90Y-DOTATOC.
PURPOSE Patients with neuroendocrine tumors (NET) often present with disseminated liver metastases and can be treated with a number of different nuclides or nuclide combinations in peptide receptor radionuclide therapy (PRRT) depending on tumor load and lesion diameter. For quantification of disseminated liver lesions, semi-automatic lesion detection is helpful to determine tumor burden and tum...
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...
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 کاملTwo and Three Dimensional Monte Carlo Simulation of Magnetite Nanoparticle Based Ferrofluids
We have simulated a magnetite nanoparticle based ferrofluid using Monte Carlo method. Two and three dimensional Monte Carlo simulations have been done using parallel computing technique. The aggregation and rearrangement of nanoparticles embedded in a liquid carrier have been studied in various particle volume fractions. Our simulation results are in complete agreement with the reported experim...
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...
