Periodic review of imaging protocols for different modalities is an essential part of continuous radiological quality assurance.
CT examinations in the thoracic region are currently considered as a gold standard for the evaluation of various diseases. Therefore,
it is particularly important to minimize patients’ exposure,
which can be achieved by modifying and optimizing scanning parameters.
Multidetector CT protocols can be directly modified in a variety of ways.
These include using an automated exposure control system or modifying individual acquisition parameters such as the field of view,
the number of
peak voltage (kVp setting),
tube current–time product or the pitch.
The purpose of our study is to present the effect of modifying certain parameters of a routine chest protocol on the effective dose received by the patient.
