For this meeting, we invite presentations on the topic of sample size and power in imaging studies. The session would be particularly suitable for imaging studies that have atypical designs or other complexities that mean standard methods for sample size and power calculation cannot be used.

We are currently looking for expressions of interest for 20-30 minute presentations. There may be some flexibility in timing depending on the preference of the presenter.

Please email Tom Fanshawe with the following information (be brief, 1-2 sentences per section):

  • Name and institution
  • Clinical application area (for proposed presentation)
  • Objective of study
  • Description of design of study
  • Description of data collected (or planned)
  • Description of method used in sample size or power calculation

Details of how to register for the meeting will be announced at a later date. There will be no charge for this event.
