background: measurement of absolute or differential renal function using radiotracers plays an important role in the clinical management of various renal diseases. gamma camera quantitative methods in approximation of renal clearance may potentially be as accurate as plasma clearance methods. however some critical factors such as kidney depth and background counts are still troublesome in the u...

objective(s): the ability to measure cellular proliferation non-invasively in renal cell carcinoma may allow prediction of tumour aggressiveness and response to therapy. the aim of this study was to evaluate the uptake of 18ffluorothymidine (flt) pet in renal cell carcinoma (rcc), and to compare this to 18f-fluorodeoxyglucose (fdg), and to an immunohistochemical measure of cellular proliferatio...

  The common use of maternal ultrasonography has increased the apparent incidence of neonatal hydronephrosis. Many of these cases are found to have partial obstruction at the ureteropelvic junction (UPJ). These patients are safely managed in our institution with careful observation and only occasionally require surgical intervention. The authors present two contrastin...

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,...

A 64-year-old woman, with amyloid related kidney failure (On renal dialysis) had a bone scan because of pain in the right upper femur. The 99m Tc-MDP images revealed marked hepatic uptake. In addition, there was right proximal femoral concentration of radiotracer, which corresponded to a fracture site. As an added finding, the same femor demonstrated circumferential uptake at the lower po...

Objective(s): The ability to measure cellular proliferation non-invasively in renal cell carcinoma may allow prediction of tumour aggressiveness and response to therapy. The aim of this study was to evaluate the uptake of 18Ffluorothymidine (FLT) PET in renal cell carcinoma (RCC), and to compare this to 18F-fluorodeoxyglucose (FDG), and to an immunohistochemical measure of cellular proliferatio...

A 14 years old girl, with documented Ewing's sarcoma, was treated by both chemotherapy and surgery. An initial bone scan (TC-99m-MI)I*) did not reveal a renal lesion. However, following therapeutic irradiation, there was retention of the bone imaging agent in a portion of the kidney that had been included in the radiation field. This reflected the effects of radiation related parenchymal ...
