Talk Title: Noncontrast Perfusion MRI and Dynamic MR Angiography

Series: Department of Biomedical Engineering: Systems Cellular-Molecular Bioengineering Distinguished Speaker Series

Abstract: Arterial spin labeling (ASL) is an emerging noninvasive MRI technique to measure cerebral blood flow (CBF) by utilizing magnetically labeled arterial blood water as an endogenous tracer. While in the past ASL has been limited by the low signal-to-noise ratio (SNR), recent technical development at high and ultrahigh magnetic fields, array receive coils and more efficient spin labeling and image acquisition methods has brought ASL to the frontier of both basic and clinical neuroscience. In this talk I will review the latest technical development of ASL and representative clinical applications in neurologic disorders such as stroke and arteriovenous malformation (AVM). Another new ASL technique is 4D non-contrast dynamic MR angiography (dMRA) that is able to visualize and quantify the dynamic flow pattern of labeled blood through the cerebrovasculature with millisecond temporal resolution and millimeter spatial resolution. I will showcase representative clinical applications of 4D dMRA, and discuss a novel method for assessing cerebral vascular compliance or arterial stiffness.
