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...

Renal scintigraphy is a physio-functional exploration permitting the exploration and assertion of unilateral renal agenesis. We report the case of a patient followed for a right hydronephrosis having revealed an agenesis of the contralateral kidney confirmed by 99mTc-DMSA scintigraphy. Also 99mTc-DTPA scintigraphy allowed the evaluation of the permeability of the urinary tract of the single rig...

OBJECTIVE Dynamic renal scintigraphy complemented by late gravity assisted postvoid images to 60 minutes is a frequently used diagnostic test in the evaluation of hydrone¬phrosis. The objective of this study is to evaluate the effectiveness in acquiring images at 180 minutes to calculate the late output fraction (LOF) of 99mTc-DTPA in the diagnosis of ureteropelvic junction obstruction (UPJO). ...

PURPOSE: The suitability of 99mTc-diethylenetriaminepentaacetic acid (DTPA) and 99mTc-sulphur colloid (99mTc-SC) as tracers in gamma Scintigraphy for the evaluation of colon-specific drug delivery systems was assessed in healthy volunteers. METHOD: Sodium chloride core tablets containing either 99mTc-DTPA or 99mTcSC were prepared and compression coated with two different quantities of guar gum....

Introduction: The selection of   optimal treatment of obstructive nephrouropathy requires information about the functional status of each kidney. Nuclear renal scanning objectively measure differential renal function, multiple studies have demonstrated the role of assessment of renal perfusion and GFR with triphasic CT. The aim of this study is to assess the role of CT based on renal parenchyma...

nuclear medicine methods have important role in the evaluation of transplanted kidney. in this study 58 99mtc-dtpa scans were performed in 38 patients. this method has 90% sensitivity and 96% specificity. in the cases of normal transplanted kidneys, function correlation between doppler sonography and scanning was more than dysfunctioning kidneys.

Angiotensin converting enzyme (ACE) inhibitor-induced renal failure has been reported in bilateral renal artery stenosis and in stenosis in solitary kidneys, but not in unilateral renal artery stenosis. In these patients, however, a functional impairment of the kidney ipsilateral to the stenosis can often be detected after ACE inhibition by scintigraphic techniques employing glomerular radionuc...

BACKGROUND Two 99mTc-DTPA attached estrone derivatives were synthesized and their radiopharmaceutical potential was determined using female albino Wistar rats. MATERIALS AND METHODS Two novel radiolabeled estrone derivatives, 99mTc-2,2',2"2"'-(2,2'-(2-(3-methoxy-13-methyl-17-oxo-7, 8, 9, 11, 12, 13, 14, 15, 16, 7-decahydro-6H- cyclopenta[a]phenanthren-2-ylamino)-2- oxoethylazanediyl) bis(etha...
