Logistical factors that would be necessary to implement CT colonography population screening

Test characteristics	Patient management considerations
Access and availability	Information systems to (a) send out invitations for initial screening with integrated reminders to ensure participation and (b) recall individuals for repeat screening
High diagnostic accuracy and sensitivity	Consensus population age for CTC-screening
Acceptability	Management and treatment pathways for colonic findings
Consensus quality assurance and training for reporting radiologists, including evidence-based KPIs	Integration with other screening programmes
Safety monitoring system to identify and manage adverse events	Management pathways for extracolonic findings
Cost-effective in comparison to alternative screening modalities

CTC, computed tomographic colonography; KPI, key performance indicators.
