Radiology resident MR and CT image analysis skill assessment using an interactive volumetric simulation tool – the RadioLOG project

Published in: European Radiology | Issue 2/2017

Abstract

Objective

Assess the use of a volumetric simulation tool for the evaluation of radiology resident MR and CT interpretation skills.

Material and methods

Forty-three participants were evaluated with a software allowing the visualisation of multiple volumetric image series. There were 7 medical students, 28 residents and 8 senior radiologists among the participants. Residents were divided into two sub-groups (novice and advanced). The test was composed of 15 exercises on general radiology and lasted 45 min. Participants answered a questionnaire on their experience with the test using a 5-point Likert scale. This study was approved by the dean of the medical school and did not require ethics committee approval.

Results

The reliability of the test was good with a Cronbach alpha value of 0.9. Test scores were significantly different in all sub-groups studies (p < 0.0225). The relation between test scores and the year of residency was logarithmic (R² = 0.974). Participants agreed that the test reflected their radiological practice (3.9 ± 0.9 on a 5-point scale) and was better than the conventional evaluation methods (4.6 ± 0.5 on a 5-point scale).

Conclusion

This software provides a high quality evaluation tool for the assessment of the interpretation skills in radiology residents.

Key Points

• This tool allows volumetric image analysis of MR and CT studies.

• A high reliability test could be created with this tool.

• Test scores were strongly associated with the examinee expertise level.

• Examinees positively evaluated the authenticity and usability of this tool.
