Conclusions and results of the 'Testing visualised' project(Publicatie)

The 'Testing visualised' research project has shown that the testing of radiological image interpretation using 3D image questions scores better in a number of quality-related areas than testing using 2D images. The project also sheds more light on the knowledge and skills required for radiological image interpretation.

Testing radiological image interpretation skills

It is currently possible to generate hundreds of consecutive cross-sectional images of the human body in a matter of seconds. Nevertheless, the testing of radiological image interpretation skills is still carried out using 2D images. The 'Testing visualised' project worked with students and medical interns to find out whether and how the quality of the testing of these skills could be raised using 3D images (volume imaging).

3D image questions result in better quality

The project demonstrated that 3D image questions outscored 2D questions in all quality aspects: superior reliability and a better correlation with an external validation measurement (dissecting room tests). Furthermore, the practicality of testing using volume imaging was good and students also expressed satisfaction with the new method of testing.

Greater insight into image interpretation skills

Greater insight was also gained into the knowledge and skills required to interpret images. Volume imaging engages more thinking processes and places greater emphasis on perception. 2D images place a greater focus on making a diagnosis. However, since students in general spend more time answering volume imaging questions, it is important to consider continuously whether the test objective justifies the added investment in time.

Test form implemented

The new digital test form has been established as a permanent part of all radiology tests administered by the medical degree programme at Utrecht University. Based on the experiences of medical students, the new method of radiological testing will be introduced nationally for the testing of trainee research assistants in radiology via the project 'Digital testing using images, an additional dimension'. A business model is also being developed for VQuest, the digital testing programme for image interpretation tests.

'Digital tool VQuest developed for image testing'

'Major technological developments have brought about radical changes to the practice of radiology, and consequently, to the complex skill of interpreting radiological images. The education sector is responding to these developments by introducing medical students to 3D scans early on in their degree programmes. The digital testing tool VQuest has been specially developed for testing using images. The first results and experiences are positive.'

Testing and Test-Driven Learning SURF grant programme

Institutions involved in the project were the Utrecht University Medical Center and Utrecht University. This project is part of the SURF programme 'Testing and Test-Driven Learning'. This programme examines the positive effects of supra-institutional collaboration in the area of digital testing on the study success of students, the workload of lecturers and the quality of tests.
