title: Evaluation of a computer program ('disect') to consolidate anatomy knowledge: a randomised-controlled trial.
abstract: BACKGROUND
  The teaching of anatomy to medical undergraduates continues to develop. Medical imaging can accurately demonstrate anatomy. 'disect' is a computer program which manipulates and reconstructs real CT images in 3-D.
  
  
  OBJECTIVE
  To implement and assess a novel computer-based imaging resource.
  
  
  METHODS
  Third-year undergraduate medical students at the University of East Anglia were randomised to different methods of delivering the program - either self-directed use or guided use with worksheets. Knowledge of gastro-intestinal anatomy was assessed using a 20-item test. Attitudes to using 'disect' were evaluated using Likert scales.
  
  
  RESULTS
  Most students reported the program was easy to use and a valuable resource for learning anatomy. There was no difference in scores between guided use and self-directed use (10.7 marks versus 10.6 marks, p = 0.52). Students who undertook the anatomy special study module, which involved dissection of the digestive system, performed best (12.8 marks versus 9.9 marks, p = 0.005).
  
  
  CONCLUSIONS
  Students can adequately use a computer program to see major anatomical structures derived from CT scans. Students reported that learning anatomy can be aided by the imaging-based resource. Learning anatomy is a multi-modal activity and packages like 'disect' can enhance learning by supplementing current teaching methods.
