A 73-year-old male was diagnosed with clear-cell renal carcinoma in 2002. He had right nephrectomy, developing thereafter metastases in both adrenal glands and in the right gluteus region. He received immunotherapy and remained with stable diseases until august 2011, when suddenly unfold an unstable condition, developing a renal failure with elevation of creatinine levels and need of dialysis. ...

Absract ✓ Objective : To develop a Convolution Neural Network (CNN) and discuss its performance in the estimation of Glomerular Fifiltration Rate (GFR) for patients with chronic kidney disease (CKD). Methods A total 112 were enrolled this study. The GFR is measured by 99mTc-DTPA renal dynamic used as standard after normalization body surface area imaging. We established CNN model verified compa...

The objective of this study was to evaluate the Role of MRU as a single imaging modality in evaluation of Pelvi-ureteric junction obstruction. 40 patients of hydronephrosis suspected to have PUJ obstruction were enrolled for the study from May 2010 to Nov. 2012. All patients under went USG, intravenous Urography (IVU), Glomerular filtration rate (GFR) Calculation by Cockcroft-Gault formula and ...

BACKGROUND Radionuclide techniques, as direct radionuclide cystography and (99m)Tc-DMSA scintigraphy, have been used in evaluation of vesicoureteral reflux (VUR) and reflux nephropathy (RN) in children. Dynamic (99m)Tc-DTPA scintigraphy is reserved for evaluation of differential renal function and obstruction in children, where hydronephrosis is detected by ultrasonography (US) pre- or postnata...

tc-99m-ec is a new renal radiopharmaceutical introduced as an alternative for tc-99m mag3. twenty-three normal volunteers and patients in different .stages of renal disease were evaluated with te-99m ec and tc-99m dtpa. the mean initial uptake of ec was significantly higher as compared to dtpa. there was a high correlation between rectangular and hand-drawn rols for kidney and background, 0.96 ...

Introduction:Diethylenetriaminepentaacetic acid (DTPA) is a chelating agent used as a radiopharmaceutical compound, 99mTc-DTPA, for renography. Doxorubicin (DOX) on the other hand is an effective chemotherapy drug used to treat a variety of solid malignancies.  Both 99mTc-DTPA and DOX may be used in close succession in patients undergoing DOX based chemoth...

Biocompatible gold nanoparticles (AuNPs) are particularly interesting for photo-thermal therapy (PTT) of cancer treatment because their ability to convert light into heating efficiently. Nevertheless, the random accumulation AuNPs in tissues, mainly determined by retention time bloodstream, is one main limiting factors use PTT applications. For this reason, efficient targeting and monitoring se...

99m The use of Tc-DTPA is for brain imaging renal flow study, and glomerular filtration rate measurement. Following intravenous injection, 99mTc-DTPA is rapidly cleared from the blood by glomerular filtration. Renal retention is 7% of the injected dose at 1 h and 95% is excreted within 24 h. It is neither secreted nor reabsorbed by the tubules and has negligible biliary excretion and eliminatio...
