Renal cortical scintigraphy in children : estimation of differential function with MAG3 and DMSA
Calculating the split renal function and its contribution to the global function on radionuclide static scintigraphy with DMSA is widely used in children population in evaluation of renal parenchima. Dynamic tracer MAG3 is rarely used for this purpose. The aim of this study was to compare differential function obtained with DMSA and during parenchymal phase of dynamic study with MAG3. DMSA scintiscans of 39 children reffered to our department (32 girls, 7 boys, mean age 8.5, range 2-15 years), were compared to the initial phase (first 60 - 120 sec) of the MAG3 study performed in the same patient . Conditions of detection were the same for both procedures (the same gamma camera, supine position with collimator underneath) and the time elapsed between two studies did not exceed three months. Regions of interest were manually drawn over each kidney on DMSA and MAG3 scintiscans, respectively. The results showed that in 90% of cases split renal function (ratio) calculated from both procedures showed variations smaller than 5%. Moreover, in more than two thirds (69%) of the cases split renal function differed less than 2%. From the results obtained we concluded that renal parenchymal uptake in children can be succesfully measured during the initial phase of MAG3 study as well as with DMSA. The advantage of performing MAG3 study in evaluation of renal parenchima as an initial nuclear medicine procedure is in a possibility to get more information (function, collecting system), and in the same time diminish radiation exposure. Only in minor proportion of children DMSA may still be necessary.
