UNLABELLED The purpose of the study was to compare diuresis renography scan interpretation generated by a renal expert system with the consensus interpretation of 3 expert readers. METHODS The expert system was evaluated in 95 randomly selected furosemide-augmented patient studies (185 kidneys) obtained for suspected obstruction; there were 55 males and 40 females with a mean age +/- SD of 58...

Technetium-99m MAG3, a technetium-labeled analog of hippuran, was compared with [131I] hippuran using a simultaneous dual isotope study in 20 patients. The plasma clearance for MAG3 was lower than that of hippuran, but its plasma concentration was higher, resulting in similar rates of excretion and similar renal time-activity curves. Apart from better statistics with the technetium-labeled agen...

About 14 years have passed since Fritzberg et al. developed 99mTc-MAG3 in 1986. The biological properties of this radiopharmaceutical are somewhat different from radioiodine labeled hippurate: it exhibits higher protein binding, slower blood clearance, higher extraction efficiency by tubular cells and larger excretion into the bile than the latter. Nonetheless, it has been widely used as the ag...

OBJECTIVE To assess the evolution of individual renal function during the maturation process in terms of single kidney glomerular filtration rate (SKGFR) and split function in children with unilateral complex renal duplication. STUDY DESIGN We retrospectively reviewed the records of 44 children with unilateral complex duplex kidney. All affected kidneys had a poor or nonfunctioning dysplastic...

The authors present a comparison of the findings for thallium-201 (Tl-201), Tc-99m MAG3 and Tc-99m MDP in subacute and chronic radiation nephritis in a 9-yr-old boy who was treated by radiation therapy for alveolar rhabdomyosarcoma of the left chest wall by a radiation port that partially included the left kidney. Tl-201 imaging three and six months later showed a cortical defect in the left ki...

radionuclidic techniques may provide assessment of glomerular filtration rate (gfr) effective renal plasma flow (erpf) or individual renal function. several agents were available for determination of these parameters such as ¹³¹i-oih (o-iodohippurate) and different derivatives of dads (diamidodisulfur). oih has the disadvantage of imparting a relatively high absorbed radiation dose to the patie...

RATIONALE AND OBJECTIVES The purpose of this study was to evaluate the influence of hydration status upon renogram patterns and renal physiological parameters and clarify the differences between DTPA and MAG3 studies in normal volunteers. MATERIAL AND METHODS The study populations were 22 kidneys of 11 volunteers with no history of hypertension or renal disease with normal serum creatinine le...

PURPOSE To evaluate (99m)Tc-mercaptoacetyltriglycine diuretic renograms for diagnosing stomal obstruction in tubeless cutaneous ureterostomy. MATERIALS AND METHODS Cutaneous ureterostomy was performed in 29 patients (56 renal units) with a minimum follow-up period of 12 months. Stomal obstruction was evaluated with (99m)Tc-mercaptoacetyltriglycine diuretic renography 3 months after surgery. R...
