AIM The aim of this study was to assess the degree of alterations of renal function by using 99m-technetium dimercaptosuccinic acid ((99m)Tc-DMSA) and 99m-technetium diethylenetriaminepentaacetic acid ((99m)Tc-DTPA) scintigraphy in spinal cord injury (SCI) patients. MATERIAL AND METHODS Twenty-two consecutive SCI (15 paraplegic and 7 tetraplegic) patients (mean age: 49.1±13.4 years) who had n...

INTRODUCTION The aim of this study was to investigate power Doppler ultrasonography for diagnosis and prediction of scarring compared with technetium Tc 99m dimercaptosuccinic acid scintigraphy in acute pyelonephritis. MATERIALS AND METHODS Sixty-six children, aged 2 months to 6 years old, admitted with clinical and biological signs of their first febrile urinary tract infection were studied....

Due to the high variance in available protocols on iodide-131 ((131)I) ablation in rodents, we set out to establish an effective method to generate a thyroid-ablated mouse model that allows the application of the sodium iodide symporter (NIS) as a reporter gene without interference with thyroidal NIS. We tested a range of (131)I doses with and without prestimulation of thyroidal radioiodide upt...

OBJECTIVE To evaluate and compare the usefulness of cineventriculographies, before and after nitrate use, to technetium-99m sestamibi scintigraphy for the identification of myocardial ischemia. METHODS Twenty-six patients were studied at basal conditions and 5 minutes after intravenous administration of isosorbide mononitrate (0.3 mg/kg), to evaluate the performance and regional wall motion o...

Reductive nitrosylation and complexation of ammonium pertechnetate by acetohydroxamic acid has been achieved in aqueous nitric and perchloric acid solutions. The kinetics of the reaction depend on the relative concentrations of the reaction components and are accelerated at higher temperatures. The reaction does not occur unless conditions are acidic. Analysis of the X-ray absorption fine struc...

Thyroid scintigraphy is a method that formed more than 60 years ago and retains its importance for the diagnosis assessment of risk nodular malignancy. The review examines use scintigraphic in functional metabolic goiter. Prerequisites thyroid nodes screening with short-lived 99mTc-pertechnetate are outlined. Information provided on principles preparation pharmacokinetics, as well variants acti...

In nuclear medicine, the process of labeling of cells and molecules with Technetium-99m almost always requires the use of a reducing agent, since the eluate obtained in the generator as pertechnetate ion is not easily connect to other chemical species. Since the use of products containing stannous chloride is increasingly growing by humans, has become a stimulating attempt to better understand ...

The compound (n-Bu4N)2Tc2Br8 was prepared by the metathesis of (n-Bu4N)2Tc2Cl8 with HBr (g) in dichloromethane and characterized by X-ray absorption fine structure spectroscopy and UV-vis spectroscopy. Analysis of the data gives a Tc-Tc distance of 2.16(1) A and a Tc-Br distance of 2.48(1) A. The Tc(III) oxidation state was inferred by the position of the edge absorption, which reveals a shift ...

BackgroundEarly diagnosis of transthyretin cardiac amyloidosis (ATTR-CA) is important. The aim this study was to validate the ‘Kumamoto criteria’ for prediction technetium-99m pyrophosphate (99mTc-PYP) scintigraphy positivity.MethodsOne hundred fifty patients (median age: 79.4 years, 117 males) with possibility ATTR-CA who underwent 99mTc-PYP were assessed. We divided into 4 groups (groups scor...
