BACKGROUND The purpose of this study was to clarify the value of renal drainage half-time in the evaluation of pediatric hydronephrosis after dismembered pyeloplasty. METHODS We reviewed the records of 30 children who underwent dismembered pyeloplasty for unilateral ureteropelvic junction obstruction with no other associated urological abnormality. The follow-up duration was more than 5 years...

To better understand the factors that govern the target-to-background ratios of 111In-diethylenetriaminepentaacetic acid (DTPA) polypeptides, we studied 111In-DTPA-octreotide and a model nontargeted compound, 111In-DTPA-poly(D)lysine-biotin. We evaluated the fate of 111In-DTPA-octreotide after it localizes in somatostatin receptor-positive tissues and sought to determine why such a large fracti...

Objective- To consider the use of renal scintigraphic evaluation of kidney function in Persian cat and make a comparison between 99mTechnetium ethylenedicysteine and 99mTechnetium diethylenetriaminepentaacetic in renal scintigraphy. Design- Descriptive study Animals- 6 male healthy adult Persian cats - no clinical sign of renal disorders and prior to presentation. Proce...

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...

Many volatile anesthetics have long been thought to affect pulmonary functions including lung ventilation (LV) and alveolar epithelial permeability (AEP). The purpose of this study is to examine the influence of volatile anesthetics on LV and AEP by noninvasive radionuclide lung imaging of technetium-99m labeled diethylene triamine pentaacetic acid radioaerosol inhalation lung scan (DTPA lung s...

We report a patient with DTPA and DMSA uptake on unsuspected bone metastases. He had severe pain due to grade 3 hydronephrosis of his left kidney. When Tc-99m DTPA and DMSA renal scanning were performed for preoperative evaluation, abnormal radiopharmaceutical uptake on the iliac area was noted. Pancreatic adenocarcinoma metastases to bone were subsequently defined. This patient is a very demon...

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...

background renal scintigraphy with technetium 99m labeled dimercaptosuccinic acid (99mtc-dmsa) is a traditional imaging technique commonly used to detect renal scar in patients with probable vesicoureteral reflux (vur) and/or urinary tract infection (utis). we determined whether normal results of dmsa renal scan obviate the need for voiding cystourethrography (vcug) in evaluating children with ...
