Value of Fibertracking for Target Definition and Pre-planning Requirements for Safe Thalamotomies

Ausaf Bari, MD, Neurosurgeon at UCLA Medical Center discusses fibertracking and its use in stereotactic radiosurgery (SRS) as well as cranial nerve imaging that has been done at his institution. He addresses the need in medical imaging for patient-specific connectivity information and outlines the use of connectivity-based imaging using diffusion tensor imaging and tractography to delineate nerve fibers, such as the trigeminal nerve and optic pathway, for targeting. With the support of case examples, he then delves into applying this principle to radiosurgical thalamotomies and demonstrates how connectivity impacts efficacy.

Video Transcript

I'm going to talk about both fibertracking and its use in SRS, as well as some cranial nerve imaging that we've done at our institution. These are my disclosures. So as we all know, stereotactic radiosurgery is a field that's been enabled by advancements in technology and increased precision. So we've gone from the era of whole brain radiation and conventional radiation. And with advances in anatomical or structural MRI, we've been able to go into this era of stereotactic radiosurgery, and we believe that with connectivity-based and network-based imaging and fibertracking, we're going to go into a new era...
