Impact of the background region of interest in the relative renal function. Annual Congress of the European Association of Nuclear Medicine, Birmingham (UK), October 15-19, 2011. Poster.http://hdl.handle.net/10400.21/212Renal scintigraphy with 99mTc-dimercaptosuccinic acid (99mTc-DMSA) is performed with the aim of detect cortical abnormalities related to urinary tract infection and accurately quantify relative renal function (RRF). For this quantitative assessment Nuclear Medicine Technologist should draw regions of interest (ROI) around each kidney (KROI) and peri-renal background (BKG) ROI, although, controversy still exists about BKG-ROI. The aim of this work was to evaluate the effect of the normalization procedure, number and location of BKG-ROI on the RRF in 99mTc-DMSA scintigraphy.engMedicina nuclearCintigrafiaFunção renalconference object
