Probing tissue motion using magnetic resonance imaging

Raja Muthupillai, Ph.D.
Magnetic resonance imaging methods provide the flexibility to probe molecular motion in
living organisms at vastly different scales – from sub-micron level, incoherent diffusive
motion to organized motion of blood blow in vessels with velocities on the order of fraction
of m/s. MR imaging methods sensitized to tissue motion can provide great insight into
physiology of living tissue, e.g., to diagnose acute stroke, tissue micro-circulation or
perfusion, tissue stiffness, bulk blood flow, and tissue deformation. This lecture will provide
a brief overview of the principles behind these MR imaging methods.
