introduction: many radiotracers have been used for sentinel node mapping with acceptable results. the main difference between these radiotracers is the particle size. in the current study, we reported defective labeling of tc-99m antimony sulfide colloid which resulted in large particle size. methods: tc-99m-antimony sulfide colloid was used for axillary sentinel node mapping of 45 breast cance...

introduction: sentinel lymph node biopsy is the standard procedure for lymph node staging in intermediate thickness melanoma. in iran, this procedure has not been addressed sufficiently. in this study, we report our experience in this area. methods: ten consecutive patients with intermediate thickness melanoma where included in our study. 1.5 mci of tc-99m antimony sulfide colloid in two divide...

introduction: there is a consensus in the literature that sentinel lymph node biopsy is the standard procedure for axillary staging in early stage (i and ii) breast cancer patients. usually during lymphoscintigraphy, the location of the sentinel lymph node is marked on the skin by an indelible ink. in this study we evaluated this issue in our patients. methods: 40 patients with the clinical dia...

introduction: in the current study, we evaluated the feasibility of body outlining using tc-99m filled flood source for lymphoscintigraphy imaging. methods: 80 patients were included in the study. sentinel node mapping was done using tc-99m antimony sulfide colloid. for outlining the body a tc-99m filled flood source was used which was placed behind or lateral to the patients for anterior and ...

UNLABELLED Colloidal particle size is an important characteristic to consider when choosing a radiopharmaceutical for mapping sentinel nodes in lymphoscintigraphy. METHODS Photon correlation spectroscopy (PCS) and transmission electron microscopy (TEM) were used to determine the particle size of antimony trisulfide and rhenium sulfide colloids, and membrane filtration (MF) was used to determi...

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 colloid. Anteri...
