Pain is the commonest clinical manifestation of bone metastases. Its treatment is palliative in nature, and consists of chemotherapy, radiotherapy, hormonotherapy, diphosphonates, and drug therapy (i. e., opiates). Radioactive isotopes represent an appealing alternative to conventional treatment modalities. Among the different types of isotopes, wide clinical experience with Sm has been obtaine...
PURPOSE OF THE STUDY With rapid development in the field of nuclear medicine therapy, radiation safety of the personnel involved in synthesis of radiopharmaceuticals has become imperative. Few studies have been done on estimating the radiation exposure of personnel involved in the radio labeling of 177Lu-compounds in western countries. However, data from the Indian subcontinent are limited. We ...
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. ...
The aim was to study the influence of temperature on the transport of the hepatobiliary contrast agent Gadobenate dimeglumine (Gd-BOPTA). Rat livers were isolated and perfused with Gd-BOPTA at 12, 25, 30, 36 and 38 degrees C. After the perfusion period, biopsies were collected and the MR signal intensity was measured. Uptake and biliary excretion were quantified with radiolabeled Gd-BOPTA. MR s...
Background The aim of this study was to evaluate the palliative efficacy of localized external radiotherapy (RT) combined with systemic radionuclide (RN) therapy in patients who had multiple painful osseous metastases of different primary origins. Methods Thirty-three patients initially local external radiotherapy was delivered to the most symptomatic region in all patients. Then they receive...
Designing ideal radiopharmaceuticals for use as bone pain palliatives require the use of a moderate energy β emitter with a stable carrier molecule. Cyclic polyaminophosphonate ligands are known to form complexes with higher thermodynamic stability and kinetic inertness. The present study therefore envisages the use of a few moderate energy β emitters, viz. Lu (T1/2 = 6.71 d, Eβmax= 497 keV), S...
تهیه و تولید عوامل تسکیندهندهی درد استخوان برای بیمارانی که در مراحل نهایی سرطان قرار دارند، به طور روز افزونی در حال گسترش است. زولدرونیک اسید ](1-هیدروکسی-2-ایمیدازول-1-ایل- فسفونواتیل) فسفریک اسید مونو هیدرات[ نشاندار شده با 153Sm و 175Yb میتواند به عنوان عوامل درمانی بالقوه جهت درمان تسکینی استخوان استفاده شود. در این مطالعه، کمپلکسهای زولدرونیک اسید-153Sm و زولدرونیک اسید-175Yb با ا...
