Scar Tissue, Synthetic Data: Teaching AI to See the Invisible
Synthetic data has a seductive sales pitch: when real data is scarce, expensive, or ethically awkward to collect, generate more of it. Simple. Almost too simple. Which, in AI, usually means the invoice has not arrived yet. The paper behind this article, LGESynthNet: Controlled Scar Synthesis for Improved Scar Segmentation in Cardiac LGE-MRI Imaging, is interesting because it refuses that easy story.1 It does not merely ask whether a model can generate plausible cardiac MRI images. It asks a more operational question: can generated scar tissue help a downstream model detect and segment real scar tissue better? ...
