OBJECTIVE The practice of regular dose measurement helps to ascertain the level of occupational dose delivered to the staff involved in diagnostic procedures. This study was carried out to evaluate the dose exposed to the hands of radiologists and a radiologic technologist carrying out HSG and radionuclide bone scan examinations in several hospitals in Nigeria. METHODS Radiation doses exposed...

Data have been collected and physical and statistical models have been constructed to estimate unknown occupational radiation doses among 90,000 members of the U.S. Radiologic Technologists cohort who responded to a baseline questionnaire during the mid-1980s. Since the availability of radiation dose data differed by calendar period, different models were developed and applied for years worked ...

magnetic resonance imaging (mri) uses a constant magnetic field and radio waves, a non-invasive method for examining tissues, organs and the skeletal system. the advantages and disadvantages of mri is not fully understood. in the computerized tumor (ct) scan, as an invasive method, the x-rays of the body is used for tomography; which different x-ray attenuation coefficient in tissues as well as...

Technical innovation in radiation therapy (RT) such as stereotactic irradiation, intensity modulated RT, image-guided RT, and brachytherapy using remote controlled after-loading system have made it possible to deliver ideally distributed radiation dose to the target with great accuracy, while sparing the adjacent organs at risk. As a result, tumor control rate by RT improved markedly and became...

SUMMARY Bacterial isolates were made from the intestinal tracts ofcarious species of cockroaches (Periplaneta americana, Periplaneta brunnea, Periplaneta australasiae, Neostylopyga rhombifolia, Nauphoeta cinerea) trapped from hitchens and stor...

The PET procedure involves the administration of short-lived positron emitting radioisotopes to the body. The choice of PET as diagnostic method is increasing and the inclusion of PET systems as part of an imaging center is becoming more widespread. In our PET center, the number of clinical 18F-FDG PET scans has increased almost to 5000 studies per year. The increasing demand of PET studies for...
