No side effects were observed and a low effective radiation dose of 0.01 mSv /MBq was calculated.
By comparison, an average diagnostic chest CT delivers 8 mSv effective radiation dose.
A low-dose screening chest CT without intravenous contrast will be performed, delivering on average less than 1.5 mSv effective radiation dose.
The report also said: "The increase in medical radiation has nearly doubled the total average effective radiation dose per individual in the United States".
Objective: The goal of this study was to estimate the effective radiation dose for the physicians and staff members in contrast angiocardiography.
The values of mean and maximum effective doses represent approximately 12.5% and 81% of the annual effective radiation dose limit suggested by the International Commission on Radiological Protection.
Therefore, the effective radiation dose is increased and local tumor control potentially improved.
The effective radiation dose was calculated at 0.32 to 0.40 mSv, depending on the patient's age.
The effective radiation dose may be as low as 1 mSv [18, 29, 30]. .
Using retrospective ECG-gated CT, the effective radiation dose is around 2 6 mSv for patients with CHD [11].
Therefore, triple-bolus MDCT urography provides simultaneous renovascular, corticomedullary, nephrographic and excretory imaging with a reduced effective radiation dose compared to the usual multiphasic MDCT protocols [13, 14].
