AI super-resolution erases, not hallucinates, small brain lesions

A new research paper investigates the impact of super-resolution (SR) techniques on the detection of small white-matter hyperintensities (WMH) in brain scans. The study found that SR methods, while generally improving lesion detection compared to raw thick slices, predominantly cause the erasure of small, real lesions rather than hallucinating absent ones. The erasure effect was more pronounced with thicker slices, and one specific method, ECLARE, showed the best performance in recovering small lesion signals. AI
