Heterogeneous Distribution and Absorbed Dose of Radiolabeled Nanoparticles and Colloids in Sentinel Lymph Nodes
Background: For breast cancer staging, radiolabeled colloids and superparamagnetic iron oxide nanoparticles (SPIONs) are used for sentinel lymph node (SLN) imaging. This study characterized the intranodal activity distribution and absorbed dose distribution. Material and Methods: Six patients diagnosed with primary breast cancer were intradermally injected with 99mTc-Nanocoll. The SLNs were resect
