Computation of relative function of kydney at dynamic scintigraphy - influence of time period applied for computation.
 HRTÁŇOVÁ, Jana
The topic of my bachelor thesis is a computation of relative renal function at dynamic scintigraphy and an influence of the time period applied for computation. The main aim of the thesis is to establish if the usage of two different time periods for computation of relative function of kidneys at dynamic scintigraphy of kidneys has any influence on computed function. Precisely, whether the choice of time period affects the result of processing the study is acquired by dynamic scintigraphy of kidneys. Expressed hypothesis assumes that time periods between 60s and 180s which were chosen for the calculation have not the influence on calculated relative function. Dynamic scintigraphy of kidneys enabling to display function of kidney´s ability to clean blood from the observed substance and consider possible defect of kidney excretion, it is the important method of examination mainly by children patients which are the vast majority of examined patients. For the hypothesis confirmation, there was created a reference file. This file consists of children patients who were examined by dynamic scintigraphy of kidneys in the Department of Nuclear Medicine Hospital in Czech Budejovice. With a help of program of dynamic scintigraphy the relative function of kidney was computed and defined by the percentage portion of each kidney on the whole renal function. The different time periods were used for the function curve for the computation. The function curve is designed like a graph from the marked region of interest and it is the result of computer processing data which were obtained from the scintigraphic study. From obtained values, the tested criteria are subsequently determined by statistical calculations they are confirmed and given as a zero hypothesis.
