Exploring Age-Related Morphological Changes in Cerebral Arteries: A 7T TOF MRA Study

Published in The Organization for Human Brain Mapping Annual Meeting, 2024

We utilized 7T Time-of-Flight Magnetic Resonance Angiography (TOF MRA) to analyze age-related changes in cerebral arterial diameter and tortuosity, finding that aging is associated with increased diameter in large vessels, decreased diameter and tortuosity in small vessels, and potential implications for cerebrovascular health in older adults.

Age- and Sex-Related Morphological Changes in Cerebral Blood Vessels: a 7T TOF MRA Study

Published in The Alzheimer's Association International Conference, 2023

We investigated age- and sex-related morphological changes in cerebral blood vessels using 7T Time-of-Flight MRI, finding that older women show greater increases in small vessel tortuosity compared to men, potentially contributing to elevated risks of cerebral small vessel disease and Alzheimer's disease in women.

VesselMapper: A Robust Vessel Segmentation Algorithm for 3D Images

Published in The Organization for Human Brain Mapping Annual Meeting, 2023

VesselMapper is a noise-robust algorithm for 3D image vessel segmentation that characterizes morphological features of brain blood vessels in magnetic resonance angiography (MRA) images, enabling the detection of cerebrovascular changes associated with aging, disease, or treatment.
