Cerebral Magnetic Resonance Angiography (MRA) Learning: A Methodological Framework to Develop a Web-Based Interactive 3D Application for Indonesian Medical Education

Cerebral magnetic resonance angiography (MRA) is an economical and minimally invasive imaging method utilised to diagnose various neurological disorders. Nevertheless, MRA images are two-dimensional and require a solid grasp of cerebral vascular anatomy for interpretation. In modern medical education, technology-enhanced learning approaches, such as interactive applications and digital 3D models, have been embraced to improve learning outcomes. However, in Indonesia, conventional 2D illustrations in textbooks, lecture slides and anatomical specimens remain prevalent in the learning process. Recognising this disparity, the research presented here is dedicated to developing a web-based interactive 3D application for learning about cerebral MRA and exploring its potential as a supplementary learning tool for Indonesian medical students. Patient MRA data were digitally reconstructed into 3D models depicting normal cerebral vascularization, which were subsequently refined and integrated into a game engine platform to produce eight interactive 3D anatomy models. These models were then combined with relevant medical information and made available on itch.io as a web-based application to ensure broad accessibility. The application’s evaluation was completed through an online survey aimed at Indonesian medical professionals. Responses from 23 participants indicated a high usability rating (average SUS score = 72), positive comments on its usefulness as a learning aid and a significant learning motivation among the participants. While further enhancements are necessary, this research possesses the potential to serve as a valuable supplementary learning approach for integration into Indonesian medical education. Furthermore, it represents an initial step in fostering awareness towards the implementation of technology-enhanced education in the medical field in Southeast Asian countries.
