BACKGROUND: To study the value of periareolar intra-dermal injection of Tc-99m sestamibi (MIBI) for sentinel node mapping in breast carcinoma. MATERIAL AND METHODS: Fifty patients with early-stage breast cancer were included in our study. 17.5 MBq Tc-99m-MIBI was injected intradermally to 25 patients and the remainders were injected with the same dose of Tc-99m-antimony sulphide col-loid. Anterior and lateral static images were taken at 2 minutes. If sentinel lymph node was not detected, delayed imaging by up to 180 minutes was carried out. The patients were operated on The efficacy of Tc-99m sestamibi for sentinel node mapping in breast carcinomas: comparison with Tc-99m antimony sulphide colloi
