bilateral diffuse intense breast uptake was noted in a 40 year old female who was evaluated with tc-99m sestamibi (mibi) myocardial perfusion scan for possible ischemia. she was breast feeding her 1.5 year old child. the intense uptake in the breasts was superimposed on the apical and anteroapical regions of the myocardium and caused interpretation problem. we recommend considering tc-99m mibi ...

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: several radiotracers are being used for sentinel node mapping in patients with breast cancer. in the current study, we reported our experience with 99m-tc phytate for sentinel node mapping in mashhad university of medical sciences. methods: all breast cancer patients who underwent sentinel node mapping using 99m-tc phytate were included. all patients received intradermal peri-areo...

Technetium metal and Tc-Ru alloys were characterised to build a database of the Tc metal target for transmutation. The lattice parameters of Tc-Ru alloys including Tc and Ru metals measured by X-ray diffraction decrease with increasing Ru concentration. The thermal conductivity of Tc-Ru alloys including Tc and Ru metals was determined by the thermal diffusivity measured by the laser flash metho...

Introduction: Appendicitis is one of the most common surgical emergencies. In spite of the relatively high rate of negative appendectomy, as a result of miss diagnosis, uncertainty of diagnosis still continues to challenge physicians. The objective of this prospective study was to investigate the role of 99mTc-Ubiquicidin (UBI) scintigraphy in the diagnosis of acute appendicitis and ...
