Introduction: Nowadays, science mapping is considered an excellent technique for decision-makers to find solutions for problems in research planning and development. In this work, we aimed to depict a science map of “radiology, nuclear medicine, and medical imaging” in Iran. Methods: All publications indexed in Thomson Reuters Web of Science database in the fields mentioned above with at least...
Introduction: whole body bone scan is one of the most useful procedures of nuclear medicine. Accurate distribution of radiopharmaceutical is yielded by using SPECT-CT. There are concerns about the radiation dose of CT part. The present study aimed to evaluate the patients’ dose in bone nuclear medicine imaging. Methods and Materials: First of all, the dose report of CT console was calibrated u...
Background and Objective: In nuclear medicine, lung perfusion scintigraphy is performed by radiolabeled particles, 99 mTc-albumin macroaggregated. Synthesizing of the particles has some difficulties. In order to resolve this problem, chitosan microparticles were used as an alternative choice. Materials and Methods: The qualitative control tests including: the determining particles size...
Introduction: Myocardial perfusion SPECTby 99mTc-Sestamibi and 99mTc-Tetrofosmin radiopharmaceuticals usually presents a false significant increase in the radiotracer uptake in the inferior myocardium due to the uptake in organs such as liver, bowel, stomach and biliary system. The present study evaluated a suitable Slit angle for differentiating extra-car...
introduction: lymphoscintigraphy is imaging of the lymphatic system and has been integrated into the sentinel node mapping procedures. lymphoscintigraphy usually encompasses early or delayed static images. however, immediate dynamic imaging of the lymphatic basins and tumors has also been used as an adjunct lymphoscintigraphy imaging. the aim of this study was to assess the role of early dynami...
