Introduction: 99mTc–Dimercaptosuccinic Acid (DMSA) as evaluation of pediatric genitourinary abnormalities has an important role in pediatric nuclear medicine. The aim of this study was to estimate organs absorbed dose for children injected by 99mTc DMSA using MIRDOSE software and hybrid planar/SPECT method. Methods: After injection of 99mTc-DMSA, ten children with genitourinary abnorma...

Objective(s): According to the unique properties of magnetic nanoparticles, their usages in medicine and industry have increased in the last decade. Due to the vital role of liver in the body, the accumulation of CoFe2O4 and CoFe2O4@DMSA was studied. Materials and Methods:The nanoparticles were synthesized by co-precipitation method and were coated with DMSA. The techniques XRD, TEM, DLS, FTIR,...

Secure determination of the binding of 99mTc-radiopharmaceuticals to plasma (P) and blood cell (BC) constituents can help to understand the biodistribution of radiophamaceuticals. The reported precipitation studies of blood with radiopharmaceuticals have shown that the results can not be easily compared between studies. We decided to determine the "gold standard" concentration of trichloroaceti...

OBJECTIVE To apply a semiquantitative method for analysis of technetium-99m-dimercaptosuccinic acid ((99m)Tc-DMSA) renal scintigraphy for monitoring the effect of extracorporeal piezoelectric lithotripsy (EPL) in patients with calyceal stones on regional kidney function and to check whether EPL had caused any deleterious effect on the target calyceal renal parenchymal function. PATIENTS AND M...

Long-term in vivo studies in murine models have shown that DMSA-coated nanoparticles accumulate in spleen, liver and lung tissues during extended periods of time (at least up to 3 months) without any significant signs of toxicity detected. During that time, nanoparticles undergo a process of biotransformation either by reducing the size or the particle aggregation or both. Using a rat model, we...

In this study, dimercaptosuccinic acid-functionalized magnetic chitosan (Fe3O4@CS@DMSA) was synthesized via in situ coprecipitation process and amidation reaction, aiming to eliminate cadmium (Cd(II)) ions from an aqueous environment. The structure, morphology, particle size of the Fe3O4@CS@DMSA adsorbent were investigated using FTIR, TEM, EDX, TGA, zeta potential, XRD techniques, obtained resu...

OBJECTIVE To report our experience with silent ureteral stones and expose their true influence on renal function. METHODS We analyzed 506 patients who had undergone ureterolithotripsy from January 2005 to May 2010. Silent ureteral stones were calculi found in the absence of any specific or subjective ureteral stone-related symptoms. Of the 506 patients, 27 (5.3%) met these criteria (global co...

Water and life are closely linked. This has been recognized throughout history by civilizations and religions and is still the case with scientists today. Water properties are found to be very effected by magnetic and electric field. The aim of this work was to study to what extend magnetic treated water can enhance the chelation rate in cases of heavy metal ions intoxications. Thirty New Zeala...

The effect of several chelating agents (diethyldithiocarbamic acid, DDC; nitrilotriacetic acid, NTA; 2,3-dimercaptopropanol, BAL; d,l-penicillamine, PEN; 2,3-dimercaptosuccinic acid, DMSA; ethylenediaminetetraacetic acid, EDTA; and diethylenetriaminepentaacetic acid, DTPA) on the toxicity, distribution and excretion of cadmium (Cd) was determined in mice. When chelators were administered immedi...

UNLABELLED Renal length measurements are used in evaluating several abnormalities of the pediatric genitourinary tract. This study assesses reproducibility of renal length measurements obtained with 99mTc-dimercaptosuccinic acid (DMSA) SPECT. METHODS The lengths of 98 kidneys of 51 children (age range, 1-16 y; mean age, 5.4 y) who underwent 99mTc-DMSA SPECT were measured independently by 2 ob...
