UNLABELLED There has been no consensus on a standard calculational approach regarding the concept of administered activity in ventilation studies involving inhaled radioisotope gas or radioaerosols. This is caused in part by a lack of knowledge regarding the actual activity that enters the lung space (as opposed to activity introduced into the delivery system) and to the extended administration...
There is a long history of absorbed dose calculations being performed to evaluate the risks involved in the application of radiopharmaceuticals to medical studies. In the 1940s, Marinelli, Quimby, and Hine (1–3) published a set of articles that presented a summary and approach to radionuclide dosimetry. In 1956 Loevinger et al. (4) summarized the field at that point, and then in 1968 the newly ...
مقدمه: تخمین صحیح میزان دوز جذبی رادیوداروها در کاربردهای تشخیصی و درمانی در پزشکی هسته ای، به منظور ارزیابی سود و زیان رسیده به بیمار ضروری می باشد. روش mird (medical internal radiation dosimetry)، روشی معمول جهت تخمین دوز جذبی اندام ها از گسیل کننده های پرتوی داخلی است. هدف از انجام این مطالعه، تخمین دوز جذبی اندام ها ناشی از رادیوداروی mdp- 99m tc ( 99m tc-methylene diphosphonate) در بیماران...
background: therapeutic radiopharmaceuticals are designed to deliver high doses of radiation to selected target organs with an aim of minimizing unwanted radiation to surrounding healthy tissue. due to the potential of targeted radiotherapy to treat a wide range of malignant conditions, [153sm]-samarium maltolate was developed for possible therapeutic applications. materials and methods: the or...
Boron Neutron Capture Therapy (BNCT) is a relatively safer technology for killing cancer cells, one of which the Glioblastoma multiforme. One main components BNCT equipment collimator functions as an exit point epithermal neutron particles that hit cells. In addition to experimental method, research can be carried out by modeling, including using MCNPX software based on Monte Carlo Method. This...
Introduction: Nano radio-pharmaceutical therapy (NRPT) is a new method for solid tumor therapy. The treatment uses a radioactive form of radionuclide encapsulated in the poly amido amine dendrimers. The poly (amidoamine) (PAMAM) dendrimers have attracted attentions for cancer treatment by their characteristics of targeted drug carriers, delivery agents, and imaging agents in hu...
A brief overview is provided of the history of the development of internal dose methods for use in nuclear medicine. Basic methods of internal dosimetry and the systems that have been developed for use in nuclear medicine are described. The development of the MIRD system and the International Radiopharmaceutical Dosimetry Symposium series is outlined. The evolution of models and tools for calcu...

Abstract Background Patients with metastatic, castration-resistant prostate cancer (mCRPC) present an increased tumor burden in the skeleton. For these patients, Lutetium-177 (Lu-177) radioligand therapy targeting prostate-specific membrane antigen (PSMA) has gained increasing interest promising outcome data. Patient-individualized dosimetry enables improvement of success aim minimizing absorbe...
