- •
We optimized MRI parameters for imaging perivascular spaces (PVSs) at 7 T.
- •
We developed a semi-automatic segmentation method for delineating PVS.
- •
We found much larger numbers of PVSs in young healthy subjects than previously reported.
- •
We reported PVS morphological features in both centrum semiovale and subcortical nuclei.
