[Possibilities of using citon for examining the kidneys].

To determine the area of application of citon, a radiopharmaceutical produced in Hungary, a study was made of its major pharmacokinetic properties with relation to the nature and rate of its release from the blood, selective renal excretion, the time of diffusing from the plasma and the time of passing through the kidneys. A total of 45 patients were examined with the help of a computerized gamma-chamber and renograph in the course of dynamic scintigraphy and renography. Analysing the data obtained on the basis of a chamber model of the indicator behavior, using appropriate processing of the recorded curves one can conclude that the behavior of citon differed little from that of other filtrating agents, such as 99mTc-DTPA.
