Administered 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 کاملA Bayesian 3-compartment model for 99mTc-MAG3 clearance.
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...
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 کاملThe impact of 177Lu-octreotide therapy on 99mTc-MAG3 clearance is not predictive for late nephropathy
Peptide Receptor Radionuclide Therapy (PRRT) for the treatment of neuroendocrine tumors may lead to kidney deterioration. This study aimed to evaluate the suitability of 99mTc-mercaptoacetyltriglycine (99mTc--MAG3) clearance for the early detection of PRRT-induced changes on tubular extraction (TE). TE rate (TER) was measured prior to 128 PRRT cycles (7.6±0.4 GBq 177Lu-octreotate/octreotide eac...
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...
