Aims and objectives
Various methods are used in the diagnosis of congenital heart disease.
Since transthoracic echocardiography (TTE) is an available and practical method,
it is generally the first choice in these methods.
However,
aortic arch,
coronary arteries,
pulmonary artery branches,
pulmonary veins and other structures cannot be fully visualized in TTE.
Therefore more advanced imaging techniques such as cardiac computed tomography angiography (CCTA) are being more widely used for diagnosis and preoperative planning.
Especially children are more susceptible to ionizing radiation than adults,
the biggest disadvantage of CT angiography is the exposure of the patient to ionizing radiation.
Therefore,
low mAs and kVp values is used to reduce radiation dose in pediatric protocols based on the ALARA principle.
Beside this,
for reduce radiation exposure while still maintaining an image of diagnostic quality many techniques,
have been developed(1-3).
The goal of this study was to evaluate the radiation doses of prospective and retrospective ECG- triggered CCTA.
