Methods and materials
The performance of the study was made possible by developing an appropriate questionnaire (fig.
1) consisting of 3 parts with a total of 10 questions.
The questionnaire was shared in public and private facilities in Athens,
while the research did not include paediatric hospitals.
The questionnaire was in a printed and electronic form.
The electronic form was available on the social media (via Facebook) of the Hellenic Association of Radiologic Technologists.
The first part of the questionnaire,
the general one,
concerned equipment-related questions,
such as which coil was used to carry out the MRCP and the intensity of the magnetic field.
It,
also,
included general questions,
such as whether to use or not oral contrast media before screening.
The second part concerned the main protocol used to perform a MRCP examination.
At this part,
they were requested to provide information about the basic sequences performed,
as well as some technical parameters such as slice thickness,
interval,
plane level,
use of breath hold or respiratory technique,
use of parallel imaging technique and fat suppression.
In addition,
it was asked whether their department's protocol included or not,
additional sequences.
The third and final part of the questionnaire consists of questions that provide supplementary information.
The information concerns the administration of hepatobiliary contrast agent,
the implementation of dynamic MRCP with secretin (secretin-enhanced MRCP),
and the Maximum Intensity Projection (MIP).
All public hospitals and private diagnostic centres in Athens were thoroughly recorded.
Participants were assured that their details are confidential and that they will not be correlated in any way with their replies.
The questionnaires were distributed and collected in October and November of 2016.
The SPSS program was used in order to analyse the data.
