MRI-guided Focused Ultrasound: Ablation to BBB opening to Neuromodulation

Abstract: Using a large area transducer, ultrasound can be focused deep into the body without any damage to intervening tissue. In ablative applications in the brain, MRI is used for targeting and for monitoring tissue temperature. It is important to assess that an effective temperature rise is achieved at the target, without heating nearby tissue. I will describe our MR thermometry methods that are robust to patient motion. Another important application of focused ultrasound is opening the blood-brain barrier for the delivery of therapeutics, such as chemotherapy and antibodies. In ultrasound-based neuromodulation, the brain is directly stimulated, eliciting behavior such as limb twitches in rodents. For both these applications, I will describe our work to calibrate the beam pressure with patient-specific CT-based simulation and MR acoustic radiation force imaging.

Biography: Kim Butts Pauly obtained a B.S. in Physics from Duke University. She received a Ph.D. from the Mayo Graduate School where she studied diagnostic MRI physics.  After a short postdoc at Stanford, she joined the faculty in the Department of Radiology at Stanford in 1996. Her work is currently focused on MRI-guided focused ultrasound in applications ranging from cancer treatment to functional disorders. She currently has courtesy appointments in both Biomedical Engineering and Electrical Engineering and is division chief for the Radiological Sciences Laboratory within Radiology.

The Imaging Technology fair will also include a poster session followed by a reception.
