12	26	F	Abdominal wall	L groin, aberrant uptake	−	Unclear	L groin	+ (?) parailiac nodes, aberrant uptake	Unclear	−	Negative (parailiac nodes and aberrant uptake not examined)

↵* Including images obtained with ⁵⁷Co flood source.
↵^† Additional nodes detected on SPECT/CT only. Hidden = hidden by scatter radiation of injection site; IT = in-transit.
↵^‡ SPECT/CT added data were considered clinically relevant if they guided surgeon to SNs that were undetected on planar images or to SNs in another basin.
