Event information

Location: University of Birmingham

Date: 20 July 2017

Working group: Imaging studies

This meeting brought together statisticians, clinicians and other methodologists for discussion of common statistical issues in imaging studies. Challenges were illustrated by a clinical example – designing an intervention to improve interpretation of CT colonography images in the NHS Bowel Cancer Screening Programme. The issues discussed will be widely applicable to other imaging modalities. Statistical issues for discussion in this meeting included:

  • Development of a radiology training intervention for use in the bowel cancer screening programme
  • Evaluation of the radiology training intervention in a cluster RCT
  • Pros and cons of design and analysis of cluster RCT
  • Sample size issues
