Benchmarking 3D U-Net Variants for Volumetric Segmentation of the Substantia Nigra and Brain Ageing related Analysis using 7T MRI

Accurate segmentation of the substantia nigra (SN) is essential for assessing its structural integrity and volumetric changes in Parkinson’s disease and brain aging. However, it remains challenging due to SN’s small size, deep location, and low contrast on conventional MRI. This...
