Introduction High doses of ionizing radiation can lead to adverse health outcomes such as cancer induction in humans. Although the consequences are less evident at very low radiation doses, the associated risks are of societal importance. This study aimed at assessing entrance skin doses (ESDs) in patients undergoing selected diagnostic X-ray examinations at public hospitals of Akwa Ibom State,...

Background: Breast cancer is the most frequent among female population globally. Therefore, early detection helpful for effective treatments and to reduce mortality rate. Mammography a radiological examination done with low-energy X-rays detect abnormalities in breast tissue. This study aims review literature evaluate techniques, protocols, conversion factors used determine diagnostic reference...

objective(s): diagnostic nuclear medicine is being increasingly employed in clinical practice with the advent of new technologies and radiopharmaceuticals. the report of the prevalence of a certain disease is important for assessing the quality of that article. therefore, this study was performed to evaluate the quality of published nuclear medicine articles and determine the frequency of repor...

Background It has been shown that blood oxygen level dependent (BOLD) cardiac magnetic resonance imaging (CMR) is able to detect myocardial perfusion differences. However, validation of BOLD CMR against myocardial perfusion reserve (MPR) and fractional flow reserve (FFR) is lacking. We sought to analyze the potential diagnostic accuracy of BOLD CMR in comparison to invasively measured FFR which...

International standards are necessary to ensure that the diagnostic tests used by trading partners meet a minimum standard of diagnostic performance. The tests that are used to qualify animals for international movement must provide a degree of confidence that those animals which give negative test results (and therefore qualify for movement) are free of a particular infectious disease agent. W...

The application of molecular diagnostic methods may improve the timeliness and accuracy with which fungi are identified. A total of 76 well-characterized reference strains of clinically relevant Candida species and 61 clinical Candida isolates were tested by repetitive sequence PCR (rep-PCR) and PCR followed by electrospray ionization mass spectrometry (PCR/ESI-MS) and results compared against ...
