The Educational Impact of Web-based Platforms for Therapeutic Radiology in Sub-Saharan Africa

Methods and Materials: A 2-hour real-time video didactic lecture and demonstration of the left parotid tumor contouring on axial CT images was delivered using the ProKnow system and a video conferencing software. Participants were granted week-long access to practice contouring of the left parotid volume after the session. Effectiveness of the remote training was evaluated with a self-assessment questionnaire administered before and after the training. Areas of competence assessed included: (i) ability to identify anatomic structure on axial CT; (ii) ability to contour a parotid volume; (iii) ability to delineate tissues; (iv) dose-volume histogram evaluation (DVH); (v) plan evaluation; (vi) port film evaluation; (vii) cone-beam CT evaluation (CBCT). A comparative statistical analysis was undertaken to evaluate for significant changes in the average self-competence score for the various competency areas before and after intervention. The post-class survey also contained questions to determine the acceptability of the ProKnow system for training and imageguided radiotherapy planning among the participants and their access to the necessary internet services.
