Fig. 3From: Comparative research on 99mTc-Rituximab and 99mTc-sulfur colloid in sentinel lymph node imaging of breast cancerThe mean injection site clearance rates of 99mTc-Rituximab and fTcSC. The clearance rate constant (kc) for each tracer was calculated from the slope of the corresponding graph line. The (kc) for 99mTc-Rituximab (solid triangle) was 0.193 ± 0.057 h− 1, and for fTcSC (solid square) was 0.021 ± 0.007 h− 1Back to article page
