pet (positron emission tomography) is a powerful imaging technique that can provide quantitative information on the distribution of positron emitter labeled radiopharmaceuticals (pet radiopharmaceuticals) in the body. positrons (ß+) are positively charged beta particles. they are emitted when the atom is proton rich. a positron has only a transient existence. after losing all of its kinetic ene...

bangladesh is one of the smaller states in asia. but it has a long and rich history of nuclear medicine for over sixty years. the progress in science and technology is always challenging in a developing country. in 1958, work for the first nuclear medicine facility was commenced in dhaka in a tin-shed known as ‘radioisotope centre’ and was officially inaugurated in 1962. since the late 50s of t...

background: people who have been administrated radiopharmaceuticals could be a source of radiation to their relatives, medical nurses, and people who are in contact with them. the aim of this work was to estimate radiation dose received by nuclear medicine nurses. materials and methods: in this study, the dose rates at various distances of 5 – 100 cm from 70 patients, who were administered diag...

Aim: The aim of this study is to find an optimum material to protect garment for protection against 99Tcm radionuclide.Materials and Methods: Monte Carlo simulation code was applied to investigate radiation attenuation of 13 shielding materials including: Ba, gray Sn, white Sn, Sb, Bi, Bi2O3, BaSO4, Sn/W, Sb/W, Pb and W with thicknesses of 0.5 and 1 mm to determine an optimum protective garment...

Quality assurance in nuclear medicine refers collectively to all aspects of a nuclear medicine service. It would include patient scheduling, radiopharmaceutical preparation and dispensing, radiation protection of patients, staff and general public, preventive maintenance and the care of instruments, methodology, data interpretation and records keeping, and many other small things which contribu...

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 tothe morbid fear of radiation. in the philippines...

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...

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 ...

UNLABELLED Radiation doses to the fingers of occupational workers handling 99mTc-labeled compounds and 131I for diagnostic and therapeutic procedures in nuclear medicine were measured by thermoluminescence dosimetry. METHODS The doses were measured at the base of the ring finger and the index finger of both hands in 2 groups of workers. Group 1 (7 workers) handled 99mTc-labeled radiopharmaceu...
