Fig. 1 (a) Sentinel node (SN) procedure in a prostate cancer patient: planar and single-photon emission computed tomography (SPECT) imaging with lead shielding of the prostate, 2h after transrectally injecting 120 MBq of technetium-99m nanocolloid. (b) To facilitate anatomic localization of the SNs, SPECT images were fused with the pelvic staging computed tomography scan.

Fig. 2 (a) Sentinel nodes were isolated and mapped separately on a standardized lymph node (LN) template. (b) Lymphadenectomy specimens were laid out on a second LN map.

Fig. 4 (a) Number of sentinel nodes (SNs) scintigraphically detected per region and (b) number of SNs removed per region. Dimensions of the circles correlate with the numbers.

Fig. 5 (a) Number of positive lymph nodes (LN+) per region and (b) percentage of LN+ of the total number of removed lymph nodes per region in 74 patients. Dimensions of the circles correlate with the numbers. European Urology 2013 63, 450-458DOI: (10.1016/j.eururo.2012.06.057) Copyright © 2012 European Association of Urology Terms and Conditions
