[Determination of glomerular filtration in children using 99mTc-DTPA and the sequential gammagraphy method]. / Urcovanie glomerulárnej filtrácie u detí 99mTc-DTPA metódou sekvencnej gamagrafie.

ABSTRACT

The method of sequence scintigraphy of the kidney with 99mTc-DTPA (diethylene triamine pentacetic acid) and subsequent determination of glomerular filtration rate by means of a gamma camera and computer were applied in examining 160 children with different diseases of the kidneys and urinary tract. By modifying the commercial computer program a study with quantitative evaluation of some functional parameters was designed, involving also the determination of the overall and of separate values of GF 99mTc-DTPA according to G. Gates. The main advantages of the applied method are its noninvasiveness, speed, safety, low radiation load, and its relatively broad use in diagnostic nephrological practice particularly in children.
