at 30 minutes after intravenous administration of the glomerular renal agent tc-99m-dtpa, both right and left lateral views were obtained. we analyzed the ratio of optical densities (behind the ureter/in front of the ureter). in patients without gross renal failure or retroperitoneal disease, the ratio was always less than 1 (range 0.38 to 0.95, mean 0.68). this represents greater perfusion of ...

BACKGROUND The gamma camera uptake method with Tc-99m-DTPA is simple and less time consuming for the determination of the glomerular filtration rate (GFR). However, its diagnostic accuracy is debated. Gates' method and predicted creatinine clearance method were compared with plasma clearance method with Tc-99m-DTPA for the measurement of GFR. MATERIALS AND METHODS Tc-99m-DTPA renography was p...

The relief of obstruction alone is frequently not sufficient to ensure renal salvage in giant hydronephrosis. We report on our experience with plication of the renal calyces used as an adjunct to dismembered pyeloplasty in patients with giant hydronephrosis. We describe the operative technique and outcomes in ten children after a follow-up period of six months. Ten patients (six girls and four ...

The synthesis of the chitosan/magnetite nanocomposites is presented. Composites were prepared by co-precipitation of iron(II) and iron(III) salts by aqueous ammonia in the 0.1 % chitosan solution. It was shown that magnetite synthesis in the chitosan medium does not affect the magnetite crystal structure. The thermal analysis data showed 4.6 % of mass concentration of chitosan in the hybrid chi...

Abstract This paper develops a novel additive for effectively recycling old corrugated container (OCC) by functionalizing nanocellulose (NC) with diethylenetriaminepentaacetic acid (DTPA) and chitosan (CS), investigate the reinforcing mechanisms effect of developed on physical properties recycled OCC pulp handsheets. The tensile, tear burst index, air permeability, tensile energy absorption (TE...

BACKGROUND Molecular imaging of thrombus within fissures of vulnerable atherosclerotic plaques requires sensitive detection of a robust thrombus-specific contrast agent. In this study, we report the development and characterization of a novel ligand-targeted paramagnetic molecular imaging agent with high avidity for fibrin and the potential to sensitively detect active vulnerable plaques. MET...

The objective of this study was to determine the diagnostic efficacy and safety of Gd-EOB-DTPA (Eovista) at 4 doses (3.0; 6.0; 12.5 and 25 pmol Gd-EOB-DTPNkg BW [body weight]) as compared to placebo (0.9% salinc) in patients with known focal liver lesion(s) A total of 171 received contrast medium injection or placebo (0.9% salinc) Thirty five patients received placebo, 33 patients receivcd 3, 3...

BACKGROUND This retrospective study was designed to determine the efficacy of broad-spectrum antibacterials combined with percutaneous renal drainage in the treatment of emphysematous pyelonephritis (EPN). METHODS From July 1992 to September 2002, 10 patients (nine females and one male) with EPN were managed at our institution. All patients had diabetes and presented with fever and chills, fl...

PURPOSE To investigate the in vivo effects of gadodiamide (Gd-DTPA-BMA) and gadopentetate dimeglumine (Gd-DTPA) on the laboratory measurements of serum calcium, magnesium, and creatinine. MATERIALS AND METHODS Medical records from 1993 to 2004 were reviewed to identify inpatients for whom laboratory data were available regarding serum calcium, creatinine, and magnesium levels before and withi...
