The 67Ga has somewhat long physical and biological half livies with 78 hours and 600 hours respectively so we can get 67Ga-scan images for 3 or more days after once injection of 67Ga. Furthermore 67Ga Scan would be useful to search some residual tumors after surgical removal of the tumors trapped with 67Ga. However 67Ga bound with plasma proteins would be delayed in plasma clearance as approximately 10% of the dose remains in the plasma at 24 hours. If the remained 67Ga in the plasma is redistributed into the surgical wound, we wouldn't evaluate the degree of the tumor remained after surgery. So the authors examined the amounts of the remained blood 67Ga and the redistribution of the blood 67Ca into the artificial wound with 5 or more centimeters in the diameter at the neck and chest of the rabbits. The results were as follows; 1) The 67Da remained in the plasma were 12%, 5.7%, 4.2% at 24, 48 and 72 hours after 67Ca injection respectively. 2) The blood 67Ca were redistributed into the artificial wound with 5.9% at 48 hours and 6.9% at 72 hours after 67Ca injection.
