Transient Global Amnesia (TGA): A Radiology Guide

A microlearning app designed to support the learning of imaging findings in transient global amnesia (TGA).
While many online resources are available for radiology learning, they often fail to cover conditions which are less common, yet clinically significant and “spot-diagnoses” on radiological imaging. Additionally, existing resources frequently lack accessibility and user interaction. Therefore, we aimed to create a platform for learning radiology that enhances accessibility and promotes active learning in the form of a mobile application.

The app seeks to offer an intuitive and interactive approach to the radiology of transient global amnesia (TGA), a condition that presents unique imaging features for medical students/interns.It includes a hands-on tutorial that guides users in analysing radiological images of brain regions affected by TGA. The tutorial guides users from foundational concepts to pathophysiology, and differential diagnoses.

Functionality

Users interact by touch to proceed through the app. Users are presented with real clinical case images of TGA and highlighted radiological findings.  
Differential diagnosis

Example case study

Case Scenario
You are seeing a 71 year old female, admitted for sudden-onset anterograde amnesia and hyponatraemia.
History of presenting complaint
Suddenly felt confused after doing housework alone at home this morning. Brought to the AED by daughter.
Past history
No history of ischemic stroke, seizures or diabetes.Not on sedatives. Non-drinker non-smoker.

Self-test

A built-in self-test using 3D MRI models follows each learning module, enabling knowledge checks. After completion, users receive a certificate and can submit in-app feedback to guide further improvements.
Interactive

Multimedia Learning

The app integrates image, illustration, video and text content. Interactive tabs shows the user their progress, but also allow for non-linear access of the content, so that the user easily jump to specific sections which they would like to review.
The UI was programmed into touch-based formats compatible with release on the iOS platforms.
