Detection of Nanoliter-Scale Cortical Perivascular Spaces using Heavily T2-weighted MRI at 7T

This dataset contains the MRI scans of 17 healthy individuals for the study of perivascular spaces at 7T. A high resolution T2-weighted 3D TSE was optimized to enhance cerebrospinal fluid (CSF) contrast with minimal contribution from tissues. A high resolution MP2RAGE (INV1, INV2 and UNI) was acquired to segment white matter, gray matter and various cortical areas with a high accuracy. A FLAIR acquisition was also performed to detect potential white matter hyperintensities and lacunes that may be confounded with perivascular spaces. In addition, TSE CSF rescan was collected for 7 subjects and are included in this dataset.
