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...

UNLABELLED Because recent reports have questioned the traditional 2-compartment model for calculating tracer clearance after a single intravenous injection, a 3-compartment model was evaluated in this study. METHODS Bayesian statistics were used, which facilitated curve fitting by treating all subjects simultaneously. (99m)Tc-Mercaptoacetyltriglycine clearance data from 154 adults and 109 chi...

BACKGROUND Experimental models are essential tools in the development and evaluation of novel treatment options, but the preclinical model of renal ischemia-reperfusion injury is limited to the retrieval of (very) early functional data, leaving the pivotal long-term outcome unknown. The present study applies technetium-99m-mercapto-acetyl-tri-glycine [99mTc-MAG3] scintigraphy for the longitudin...

OBJECTIVE: The 24-hour creatinine clearance is the standard clinical technique to measure renal function; however, this measurement is cumbersome and inconvenient for patients. We hypothesized that a camera-based Tc-99m mercaptoacetyltriglycine (MAG3) clearance obtained simultaneously with a standard MAG3 scan would correlate well with the 24-hour creatinine clearance and could serve as a simpl...

UNLABELLED 99mTc-DMSA late static planar imaging or SPECT is being used for the investigation of focal acute pyelonephritis (APN), especially in children with urinary tract infection (UTI). Diuretic 99mTc-mercaptoacetyltriglycine (MAG3) dynamic scintirenography has been applied in the evaluation of kidney function and structure, frequently to exclude obstruction. However, in children and adults...

Aim: To assess the outcomes of anatrophic nephrolithotomy in terms stone clearance and change renal function. Study design: Observational study Place duration study: Department Urology Sindh Institute & Transplantation, Karachi from 1st January 2016 to 31st December 2021. Methodology: Fifty patients who underwent were enrolled. Outcomes measured clearance, pre post procedure eGFR, serum cre...

We quantitatively evaluated total and individual renal function by technetium-99m mercaptoacetyltriglycine (Tc-99m MAG3) renal scintigraphy before and after radiofrequency ablation (RFA) of renal tumors. Eleven patients who underwent Tc-99m MAG3 renal scintigraphy 1 week before and after RFA were evaluated (7 men and 4 women; age range: 23-83 years; mean age: 60.6 years). Five patients had soli...

UNLABELLED It has been routine at the University of Alabama Medical Center to obtain a radionuclide renal function study immediately after transplantation (usually within 3 d) that includes estimation of effective renal plasma flow (ERPF) from a single plasma sample in addition to imaging. We present here the correlation between baseline measurements and the 1-y graft survival. METHODS Two co...

Contrast-enhanced ultrasound (CEUS) is an emerging technique to evaluate tissue perfusion. Promising results have been obtained in the evaluation of renal perfusion in health and disease, both in human and veterinary medicine. Renal scintigraphy using 99mTc-Mercaptoacetyltriglycine (MAG3) is another non-invasive technique that can be used to evaluate renal perfusion. However, no data are availa...
