Quantitative estimation of the renal tubular function with 99mTc- MAG3: comparative software approach using two methods in a pediatric population. In: EANM’19 – Annual Congress of the European Association of Nuclear Medicine, Barcelona (Spain), October 12-16, 2019. Eur J Nucl Med Mol Imaging. 2019;46 Suppl 1:S880.http://hdl.handle.net/10400.21/10751Introduction - The ability to quantify function by Effective Renal Plasma Flow (ERPF) using camera-based Technetium-99m mercaptoacetyltriglycine (99mTc-MAG3) clearance methods is an accurate and time-saving technique as compared with the standard laboratory tests. Often providing information not possible with the conventional radiological modalities, this quantitative assessment can be determined by a linear formula - Modified Gates Method (MGat) - or a quadratic approach - Modified Schlegel Method (MSch). The aim of this work was to evaluate the effect of the MGat and MSch methods on the absolute value of ERPF in 99mTc-MAG3 dynamic renography.engNuclear medicine99mTc- MAG3Effective Renal Plasma FlowModified Gates MethodModified Schlegel MethodChildrenconference object
