Estimation of patient organ doses from CT examinations in Tanzania
Although the use of computed tomography (CT) in medical diagnosis delivers relatively higher radiation doses to patients than other radiological procedures, lack of optimized protocols could be an additional source of increased dose in developing countries. The aim of this study was to determine the magnitude of radiation doses received by selected radiosensitive organs of patients from CT exam...
متن کاملEthanol Concentration and Its Correlation with CNS Suppressor Drugs in Postmortem Subjects
Background: Many studies have been done in order to interpret correctly the results of ethanol analysis and its related problems. Unfortunately, it was not easy to determine BAC rate, due to postmortem different conditions or personal and clinical differences in metabolism and excretion of ethanol. The time between death and autopsy, the environmental conditions (temperature and humidity) are i...
متن کاملCT measurements of cranial growth: normal subjects.
Growth patterns of the cranium measured directly as head circumference have been well documented. With the availability of computed tomography (CT), cranial dimensions can be obtained easily. The objective of this project was to establish the mean values and their normal variance of CT cranial area of subjects at different ages. Cranial areas and its long and short axes were measured on CT scan...

متن کاملThe Monte Carlo Assessment of Photon Organ Doses from 222Rn Progeny in Adult ORNL Phantom
Introduction The potential hazards posed by exposure to radiation from radon have been of great concern worldwide, since it is especially associated with increased risk of lung cancer. Some radioisotopes of radon progeny deposited in the human lungs emit β particles followed by the γ rays. While γ rays are comparatively less damaging to the respiratory system than α and β particles, it is the p...
