Evaluation of a computer program (‘disect’) to consolidate anatomy knowledge: A randomised-controlled trial

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.Aim: 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...
