A researcher developed an AI assistant to detect hemorrhages in head CT scans using Google Colab and a free Nvidia T4 GPU. While the initial model achieved an AUC of 0.963 on one fold, further testing revealed a lower AUC of 0.86 even when the model was restricted to viewing only bone windows, where brain details are minimal. The article delves into the reasons behind these figures and analyzes the masks used by medical professionals. AI
