↵* Correlation between counting rates measured 2 h after each injection (could be calculated only in patients with > 2 SNs).
Study 1 = first examination, using ^99mTc-nanocolloid; study 2 = second examination, using ICG–^99mTc-nanocolloid; SN = sentinel node; R² = correlation of sentinel node counting rates in both studies.
