Imaging section: Statistical issues in evaluating an intervention to improve interpretation of CT colonography images

Location: Public Health Building, University of Birmingham, Edgbaston, Birmingham B15 2TT | Date: 20 July 2017
This meeting will bring together statisticians, clinicians and other methodologists for discussion of common statistical issues in imaging studies. Challenges will be illustrated by a clinical example, the development and validation of an intervention to improve and monitor the diagnostic performance of radiologists interpreting CT colonography in the NHS Bowel Cancer Screening Programmes. We expect that the issues discussed will be widely applicable to other imaging modalities.
  • Prof Steve Halligan (Radiologist, Centre for Medical Imaging, University College London)
  • Dr Sue Mallett (Statistician, Biostatistics group, Institute of Applied Health Research)

Prof Halligan will provide an overview of the clinical challenges in this area, and Dr Mallett will introduce the statistical challenges.
The meeting will include small group discussion of statistical issues including:

  • 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
