Abstract:Positron emission tomography/computed tomography (PET/CT) scanner is an irreplaceable instrument in clinical diagnosis. The exposure dose that a patient receives is the sum of the doses caused by PET and CT examination. This stu...
As mentioned, patients do incur risks from the x-rays and radiopharmaceutical in PET/CT scans.One metrics of risk from exposure to radiation is the probability of getting cancer.The probability of getting cancer is known as the stochastic r...
In conclusion, this large-scale study was designed to directly evaluate cancer risk from pediatric and young adult CT radiation exposure. The results of this study, in which much effort has gone into considering and accounting for possible biases that could affect the risk estimates, strengthen the...

We have estimated the radiation exposure to the physicians and technologists working in our PET/CT facility based on the dose rate measurement with calibrated survey meter and pocket dosimeter. The mean dose measured at the chest level per PET/CT procedure was 3.24 mu Sv and 0.62 mu Sv for ...
Radiation exposure to the patient The radiation dose with FDG PET/CT is the combination of the radiation exposure from the radiopharmaceutical (Table 1) and the CT study. The radiation dose of diagnostic CT is a matter of concern, particularly for paediatric examinations. The mean dose for a ...
However, the appropriate radiation dose remains an important issue in cardiac CT. On one hand, a too low radiation dose may result in a high level of image noise and therefore in non-evaluable images. On the other hand, using higher radiation exposure levels may put patients at unnecessary ...
Willingness to allow their child to undergo both a CT that their child's doctor recommended and one the doctor hypothetically thought was marginally indicated was also surveyed. Final surveys also assessed parents' perceived change in level of concern after reading the brochure. At the time of ...
Measurements of radiation exposure during routine CT scanning were found to average 4.2 R at the level of the ocular lens. This data was combined with CT scanning rate data from a sample of 100 patients followed in the myelomeningocele clinic. The number of scans averaged 7.75/patient with a...
