Description of activity and work performed
The retrospective clinical study,
from 2012 to 2017,
included 31 pregnant women (from the 2nd to the 38th week of gestational age),
who underwent urgent radiological services.
The performances taken into consideration were of traditional radiology,
Computed tomography (CT) and interventional radiology.
Dose evaluations were performed using softwares as PCXMC for traditional radiology,
ImPACT for Dosimetry tomography,
and CODE2 for interventional radiology.
In 68% of cases,
radiological procedures were performed when the patient was not yet aware of her pregnancy,
with an average gestational age of 3/4 weeks.
In 60% of cases,
a dose greater than 1 mSv was recorded (1 mSv,
according to the law,
is the threshold that triggers the special protection during pregnancy).
The highest observed value was 50 mSv for a CT scan.

In all examined cases,
there have been no reports of malformations or other teratogenic or stochastic effects due to exposure to ionizing radiation.
