报告内容:
Neuromodulation is one of the fundamental tools for neuroscience to explore the neural mechanisms from molecular to behavioral levels. Recently, ultrasound is found to be an effective non-invasive neuromodulation tool. This cutting-edge discovery may have great potentials to many functional brain diseases.
The most challenging technique for ultrasound neuromodulation is the accurate steering of ultrasound beams to the target position inside brain. Recent studies have proved that magnetic resonance imaging can play several valuable roles in the guidance of ultrasound neuromodulation. In the presentation, MR guided ultrasound neuromodulation techniques are reviewed, including the focus localization and visualization by MR acoustic radiation force imaging, focus steering based on the cranial skull imaging by UTE sequence, temperature monitoring by MR thermometry, brain activity monitoring and assessment by functional MRI. The principles of these techniques are briefly introduced, and some preliminary results in our group are described. It is believed that MRI is a promising and powerful imaging modality for accurate ultrasound neuromoduation.
