International Survey Reveals CT Scan Range Extension Driven by Caution to Avoid Repeat Imaging

57% (n=109) of surveyed CT radiographers extend scan range in chest and abdominal examinations, driven by caution to avoid repeat imaging, per an international survey (n=230, 42 countries). AI-assisted tools were available to 44% but used inconsistently.

• Patient-related factors, especially motion and cooperation, influenced boundary selection in up to 89% of respondents.
• Scan range planning was primarily governed by local institutional frameworks (57%), with radiographer-led or shared decision-making each reported by 39%.
• Among those with AI access, 58% used it for all CT exams, while 42% used it selectively.
