A research team from the University of Pennsylvania has reported creating a high-resolution dataset by scanning 135 ex vivo human brain tissue specimens using a 7 Tesla MRI, which provides high-resolution imaging at high magnetic field strength. The team also performed segmentation using a deep learning pipeline. Ex vivo MRI offers advantages over in vivo MRI in that it allows for high-resolution examination of brain structures and enables linking pathological measurements with morphometric measurements. However, automatic segmentation for ex vivo MRI brain mapping has not been sufficiently developed due to reasons such as lack of datasets and heterogeneity in scanning … Continue reading University of Pennsylvania’s 7-Tesla High-Res MRI Study: How UPenn’s 135 Brain Scans Uncover New Dementia and Alzheimer’s Insights
