Immunolymphoscintigraphy for Metastatic Sentinel Nodes: Test of a Model

Table 2

Mean percentages of activity in rabbit inguinal lymph nodes and liver as a ratio of activity at injection site at different times after injection, calculated from ROIs of the gamma camera images.

Percentage of injected activity (right + left foot)		Injection site	Inguinal lymph nodes	Liver
^99mTc-HIG: mean values from 4 rabbit extremities	15 min p.i.	100%	0 %	0%
	5 hours p.i.	53%	6%	4%
	22 hours p.i.	5%	2%	1%
^99mTc-nanocolloid: mean values from 4 rabbit extremities	15 min p.i.	100%	1%	0%
	5 hours p.i.	77%	9%	4%
	22 hours p.i.	42%	14%	3%
