↵* Injected dose of 99mTc-radiocolloid for SPECT and 68Ga-nanocolloid for PET.
SLNs were found both in classic sites of regional spread and in aberrant sites (boldface font). First 3 patients underwent 99mTc-radiocolloid SPECT/CT, and next 5 underwent 68Ga-nanocolloid PET/CT. Scans were obtained about 45 and 100 min after tracer injection.
