Density analysis of scintigram with flow dynamics at bolus radionuclide venography: Count correction with velocity

The authors analyse the difference in the density of dynamic scintigrams produced in radionuclide venography. The difference in density is always connected with the velocity of the radionuclide flow. The lost activity is found after multiplying the count difference calculated from the time activity curve by velocity. The importance of the investigation is that the capacity of different venous channels can be determined in radionuclide venography by this method of calculation. (orig.)
