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

Key Points

Four distinct classes of cortical pvs were identified, providing a clear classification method for future research.
Cortical pvs density was measured at three times lower than white matter, indicating significant morphological differences.
Using heavily T2-weighted MRI at 7T allowed precise identification and quantification of pvs across brain regions.
This research suggests that examining cortical pvs could enhance understanding of changes linked to neurological disorders.

Abstract

Motivation: Cortical PVS have received limited attention because of detection challenges due to their small size. However, they may hold valuable insights into neurological disorders. Goal(s): This work aims to classify and quantify cortical PVS detected in healthy participants. Approach: Using optimized 7T heavily T2-weigthed MRI, we classified PVS morphologies based on their location related to intraparenchymal arteries in connection with the cortex and quantified their density throughout the whole brain. Results: Four characteristic classes of PVS associated with the cortex were consistently identified. Cortical PVS density was highest in the insula and 3 times lower compared to white matter in the whole brain. Impact: This study lays the groundwork for assessing the diagnostic utility of detecting cortical PVS changes as well as understanding the mechanisms for structural changes in cortex due to neurological disorders.
