In 1925, Hermann Blumgart performed the first diagnostic procedure using radioactive indicators on humans; this first is well recognized. Less well recognized is the fact that Blumgart and his coworker Otto C. Yens, then a medical student, developed the first instrumentation used in a diagnostic procedure involving radioactive indicators. The instrumentation, a modified Wilson cloud chamber, tu...

introduction: active personal dosimeters (apds) are well accepted as useful and reliable instruments for individual dosimetry measurements. apds have many advantages compared with passive dosimeters for individual external radiation dose assessments. in routine monitoring, occupational exposure is carried out for verification and demonstration of compliance with the regulatory dose limits. so, ...

background: due to volatility of radioactive iodine solutions, usually internal exposure would occur in personnel that are working in nuclear medicine centers. the activities in the thyroid of individual s who work in nuclear medicine centers of north west provinces of iran were measured using nai (sodium iodide) detectors. in every center, nearly 40 - 500 mci of 131 i and 50 - 600 μ ci of 125 ...

With these codes, basic dose calculations could be made in seconds instead of hours. Another purpose of these codes was to help standardize dose calculations using recognized models, phantoms, and dosimetry techniques. In nuclear medicine community, the aim is to perform calculations to obtain dose estimates for various organs of the body once the kinetics of a radiopharmaceutical agent is esta...

introduction: this study was conducted to evaluate prevalence and risk factors for diagnostic discordance for osteoporosis due to different t-scores of lumbar spine and femoral neck. methods: in this cross sectional study demographic, anthropometric and risk factors for osteoporosis were derived from a database on 3,039 post-menopausal women who underwent bone densitometry for the first time i...

The importance of personalized medicine has been growing, mainly due to a more urgent need to avoid unnecessary and expensive treatments. In nuclear medicine, the theranostic approach is an established tool for specific molecular targeting, both for diagnostics and therapy. The visualization of potential targets can help predict if a patient will benefit from a particular treatment. Thanks to t...

Medicine is now undertaking a paramount revolution that will alter the nature of healthcare from reactive to proactive. It is imperative to integrate experimental and computational investigation in order to appreciate complex biological systems in the era of precision medicine. In light of this revolution, we necessitate to precision medicine means such as systems approaches (genomics, radiogen...
