Korte Samenvatting
Current radiology practice is based on the digital intperetation of volumetric multi-slice (MS) images (like CT and MR images), however assessment of radiological skills in undergraduate medical education is still based on two-dimensional (2D) images. Consequently, the assesment lacks authenticity, which negatively impacts validity.The researcher hypothesized that the quality of assessing radiological skills can be increased using MS images. In 2010 233 medical students, trained with MS images took a digital radiology test (version A and B) containing eleven 2D and ten MS image items (CT-scans). Participants filled out a questionnaire concerning authenticity of the assessment as an indication for validity. Mean scores and reliabilities of the 2D and MS image subtests were compared.

Inzichten
Assessment of MS images increases authenticity, which can contribute to validity. reliabilities were higher for items with MS images compared to items with 2D images. This might indicate that MS image items are more difficult than 2D image items, and therefore more discriminating.

Review
Neat and clear study, which is part of the SURF-project Toetsing in Beeld

Toepasbaarheid
Study underlines the importance of authenticity in digital assessment. Further it shows the possibility of assessment with MS-images, which is innovative.
