Development and prospective evaluation of an automated software system for quality control of quantitative 99mTc-MAG3 renal studies.
UNLABELLED Quantitative nuclear renography has numerous potential sources of error. We previously reported the initial development of a computer software module for comprehensively addressing the issue of quality control (QC) in the analysis of radionuclide renal images. The objective of this study was to prospectively test the QC software. METHODS The QC software works in conjunction with st...
متن کاملSynthesis, formulation and quality control of 99mTc-MAG3, as a renal tubular 99mTc-radiopharmaceutical kit [Persian]
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...
متن کامل99mTc-MAG3: review of pharmacokinetics, clinical application to renal diseases and quantification of renal function.
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...
متن کاملAdministered activity optimization in 99mTc-MAG3 renography for adults.
OBJECTIVE The objective of this work was to determine the minimum administered activity of (99m)Tc-mercaptoacetyltriglycine (MAG3) needed both to estimate effective renal plasma flow (ERPF) with adequate precision and to obtain good image quality. METHODS Three groups of 10 patients each were injected with 45, 71, or 132 MBq of MAG3. Renograms and perfusion and clearance images were obtained....
متن کاملFactors affecting the hepatobiliary excretion of 99mTc-MAG3: its clinical significance in routine renography.
OBJECTIVE Since the approval of mercaptoacetyltriglycine (MAG3) for routine clinical use, reports have appeared about hepatobiliary excretion deleteriously affecting available diagnostic and quantitative information. The purpose of this study was to evaluate gallbladder (GB) uptake of MAG3 in the clinical setting and its effect on the evaluation of relative renal function and imaging. METHODS...
