Planar = SPECT/CT	236
Planar < SPECT/CT	5^c
Extra-axillary nodes		1
Extra-axillary nodes		95% CI 1.00–1.00

CI confidence interval

^aUsing the number of detected nodes on planar images and SPECT/CT, Cohen’ κ was calculated to evaluate the agreement between the two methods. There was an outstanding agreement between planar images and SPECT/CT

^bSPECT/CT in this patient showed concordance with surgical results. In this patient, planar imaging showed 3 hot nodes and SPECT/CT showed 2 hot nodes. Two hot nodes were found during surgery

^cIn two patients SPECT/CT showed concordance with surgical results, in two patients planar imaging showed concordance with surgical results, and one patient could not be judged. Each patient showed one more hot node on SPECT/CT compared with planar images.
