ALB and neoplasm: A prospective consecutive study for SLN identification with preoperative SPECT/CT and planar images (technetium-99 m colloid albumin injection around the tumor) and posterior intraoperative detection with both blue dye and a handheld or laparoscopic gamma probe was reported by Díaz-Feijoo et al. A total of 35 SLN were detected with planar images and 40 SLN were identified and well-located by SPECT/CT lymphoscintigraphy (median 2.0 nodes per patient).
