Clearance of radioactivity (kBq/ml) from the blood for all individual patients. The mean curve represents the calculated mean clearance from the blood according to a two-compartment model. Activities are decay corrected to the time of injection. A distribution half-life of 1.2 h (SD 1.5) and an elimination half-life of 26.9 h (SD 2.7) were estimated
