Methods and materials
A literature search was carried out in Pubmed8 the 16th April 2018 with the terms “anatomy”,
“interventionalist”,
“surgeon”,
“need”,
“quantification”,
“report”,
“standard”,
“stenosis”,
“measurement”,
“computer tomography”,
“CT angiography”,
“head”,
“neck”.
Studies between 1995 and 2018 in English language were identified.
Articles not referring to humans were excluded.
The studies were hand- selected; the literature of the selected articles was further searched for relevant publications.
We gathered evidenced- based anatomic findings and grading schemes that would guide therapeutic decision making for clinicians who order CTA of the head and neck.
We created a questionnaire on Surveymonkey (http://www.surveymonkey.com; SurveyMonkey,
Palo Alto,
CA,
USA). It was subdivided in four sections: first,
demographic (calibration) questions; second,
opinion questions about the current status of the reports; third,
comparative questions between the current report and proposed granular concepts (standardized contents); and fourth,
free text responses regarding additional requests that may not have been addressed in the survey questions.
Before the Questionnaire was used for a large- scale survey,
it was evaluated with a small- scale pilot survey at our institution.
For the large- scale survey,
translations in French and English from the original German version were made to meet different language needs in our country.
Before launching the questionnaire,
we informed the chairs of our institution’s clinical services to which we intended to send the questionnaires.
The clinicians then received an email invitation with the survey link.
For the outside hospitals,
we sent the invitation email to the chairs of the stroke centers in our country with a request to forward to their team9.
Several reminder emails were sent in weekly intervals.
The clinicians had one month to complete the survey.
