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...

1. The spectrum of transit times of sodium o-iodohippurate (Hippuran) through the kidney can be derived from an 131I- (or 123I-) labelled Hippuran renogram by deconvolution. In the rabbit and pig, as has previously been shown in man, the frequency distribution curve for the transit times was bimodal. Since the transit time is likely to be proportional to the nephron length, the area of the firs...

Dynamic MR renography has broad clinical applications, but suffers from respiratory motion that limits analysis and interpretation. Since each examination yields at least 10-20 serial 3D images of the abdomen, manual registration is prohibitively labor-intensive [1]. An effective framework for registration and segmentation is necessary to analyze these data sets. Our purpose was to develop and ...

introduction: urinary obstructive disease is one of the most common disorders in urinary system. dilatation which is detected by sonography, is a key finding in obstruction in most of the cases, also could be found following surgery, lithotripsy and vesico–urethral reflux. radioistope diuretic washout renography is a useful method to differentiate mechanical and non mechanical obstruction. mate...

introduction: it has been suggested that calculation of differential renal function (drf) using 99mtc-dmsa may lead to overestimation of the function of an obstructed kidney. the aim of this study was to evaluate the effect of diuretic administration on the determination of drf using 99mtc-dmsa scintigraphy in patients with dilated pelvis. methods: thirty three patients, aged from 2 months to 6...

Objective: To evaluate the improvement of renal function after pyeloplasty measured by 99mTc-DTPA renography. Materials and Methods: This hospital based quasi experimental study was done in department urology, National Institute Kidney Diseases Urology (NIKDU) Bangladesh Research Rehabilitation for Diabetes, Endocrine Metabolic Disorders (BIRDEM) from July 2014 to December 2020. Sixty patients ...
