While the introduction of radioactive tracers in the study of metabolic pathways has been well-documented in clinical thyroidology as early as 1924, the widespread utilization in other clinical specialties has been hampered by slow developments in radiation-detecting devices and in the production of appropriate radiopharmaceuticals, in addition to the morbid fear of radiation. In the Philippine...

as described in the first part of this article, evidence based medicine (ebm) is a growing part of medical practice which emphasizes on the best evidence. finding this evidence by formulating an answerable question and searching strategies were described in the first part of this review. in this part, appraising the retrieved article (with the main focus on the diagnostic studies) and applying ...

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 ...

introduction: one of the major problems in the development of nuclear medicine images is the presence of noise. the noise level in nuclear medicine images is usually reduced by the analysis of imaging data in a fourier transform environment. the main drawback of this environment belongs to low signal to noise ratio in high frequencies because removing noise frequencies may remove data and times...

today, nuclear medicine has rapidly been developed so that in some cases, plays a unique role in diagnosis but unfortunalty in spite of diagnostic and therapeutic advantages, the term “nuclear” can induce worries in patients and society. in this article, base on new documents, we intend to show that this worries has no scientific basis. to produce a realistic view, regarding to radiation protec...

In 1955, the first nuclear medicine division was established in Thailand by Professor Romsai Suwannik in the Department of Radiology, Siriraj Hospil, Mahidol University in Bangkok. In 1959 four years later, the second nuclear medicine division was established in the Department of Radiology, Chulalongkorn Hospital in Bangkok. The third nuclear medicine division was started in Rajvithi Hospital i...

the production and application of pet tracers has been a unique step in the progress of nuclear medicine in last two decades. the most important pet tracers include f-18, c-11 and n-13 radioisotopes and many nuclear medicine centers throughout the globe are using them. however some new tracers are under their way to the mass administration, currently being in the clinical trials or preliminary ...
