Aims and objectives
CT examinations are the valuable diagnostic tools with the increasing role in medical practice.
Nowadays,
the number of the CT examinations performed and the associated exposure of patients seems to be the challenge from the radiation protection point of view.
In some countries,
the overalldose related to CT examinations makesmajor or even the largest share in the populationdose arising from the sources of the artificial ionising radiation [1].
To keep the patients doses on the reasonable level two actions have been undertaken: first,
establishment of...
Methods and materials
The main task of the survey was to get reliable information on the doses obtained during most-frequent CT examinations performed on the selected adult population.
The types of the examinations were obtained from the database maintained by the National Health Fund (NHF) inPoland.
The NHF collects the statistical data which are used to reimburse for the medical protocols executed.
While the CT exams are reimbursed separately,
it is easy to mine the information on their number grouped by the types of exams.
The following types...
Results
In the year 2014 the questionnaire was sent to all,
1822,
X-ray departments in Poland.
They were asked to fill appropriate data for the year 2013.
The feedback was receivedfrom 238 X-ray departments (13.1%).
Sixty-four of these departments reported CT examinations (27% of all answers).
The distribution of the CT answers by the regions is presented in Fig. 1 .
There are 2regions (Podlaskie,
Warmińsko-mazurskie) that did not respond.
The total number of examinations performed by respondents equals 267,700.
The detailed data are presented in...
Conclusion
The survey carried out in CT departments in Poland give the up-to-date snapshot of the doses obtained by patients during their CT examinations.
The returned questionnaires contained 520 values of DLP obtained during different CT examinations in Poland.
The selection of the CT examinations covers all examinations which are important for the population dose.
The annual average dose in the population (per caput) was calculated and equals 0.53 mSv.
Five examinations: head,
neck,
chest,
abdomen and pelvis share as much as 80% of the total...
