ASET Webinar Schedule for 2012

Transcription

1 ASET Webinar Schedule for 2012 Atypical Evoked Potential Testing by Chris Slaymaker, R. EEG/EP T, CNIM Jan 18th (12 noon Central time, 1pm Eastern, 11am About Chris: He has twenty five years of experience in neurodiagnostics. He earned a bachelor of science degree in biology from Mercer University in Macon, Georgia, and completed sixty-five hours in the graduate program in neurophysiology at the University of Tennessee. For eight years he worked with Ron Leppanen, Ph.D., a leading neurophysiologist who has published extensively on intraoperative neuromonitoring. Chris has spoken on all aspects of neurodiagnostics, including intraoperative neuromonitoring and anatomy and physiology of the nervous system. He was an instructor of anatomy and physiology for four years at Alpha Institute of the Healing Arts. As an officer of the Tennessee Neurodiagnostic Society, he coordinated several seminars, which attracted ENT professionals as well as doctors and nurses from all over the eastern United States. He has extensive experience in EEGs, including LTME, ambulatory, brain mapping, and electrocorticography, EPs, particularly as it applies to the cranial nerves, and cortical mapping of SSEPs and Neuropsychological testing. His presentation comes from the fact that EP testing seems to have taken a back seat to the current generation of imaging techniques. It has become difficult to get standard evoked potential testing pre-approved. It seems that doctors and insurance companies make this assumption: SSER, upper extremities (CPT 95925) is the same as a median nerve SSER SSER, lower extremities (CPT 95926) is the same as a posterior tibial nerve SSER

2 When you consider the peripheral nervous system, there are a multitude of peripheral nerves that lend themselves to evoked potential testing and there is more than just sensory signals that can be assessed. In this webinar Chris will describe techniques for performing evoked potentials from uncommon stimulation sites such as Trigeminal SSEP, Radial SSEP, Fermoral SSEP, Dermatomes, Pudendal, etc. and their usefulness in clinical studies as well as in IONM. IONM in Anterior Cervical Disc and Fusion Case Presentations by Brenda Bratton, R.

Nonpharmacologic and pharmacologic treatments will be reviewed along with suggested protocols for technologists performing clinical neurophysiologic monitoring procedures on patients with parasomnias. Comparison of MEG Source Localization Techniques by Susan Bowyer, PhD. Sept 19th (12 noon Central time, 1pm Eastern, 11am About Dr. Bowyer: Currently the Senior Staff Investigator in the Neuromagnetism Lab and assistant professor at Wayne State University in Detroit, she has worked in the Biomagnetism field for the past 15 years. She is an experienced researcher with extensive training and expertise in Magnetoencephalography

5 (MEG), computer applications and image analysis. She possesses a solid understanding of neuroimaging tools and their use in exploring normal and abnormal functioning of the brain. Her experience includes MEG study design, implementation, data collection and data analysis. She has developed MEG Protocols for studies of migraine, language cognition, spreading cortical depression, and epilepsy. She is a dedicated scientist with exceptional organizational, troubleshooting, and problem-solving skills. She has authored 30 articles in peer reviewed scientific journals. The presentation will include Dr Bowyer s research: Objective: To compare the MEG data source localization techniques (ECD, Current Distribution, Beamformer, and Coherence) for evaluating a potential epilepsy surgery patient s focus. Background: Determining the site of ictal onset can be difficult in some patients with refractory partial epilepsy. MEG is a diagnostic tool with excellent spatial and temporal resolution that can provide non-invasive interictal localizing information not available from other imaging methods. Several MEG analytical methods are used to localize epileptiform activity. We wish to determine if techniques, beyond the standard ECD technique, can provide more accurate localizing information prior to surgical resection. Methods: Fifty-four patients with refractory epilepsy were monitored with MEG. Visually identified epileptic spike activity was analyzed with four separate MEG techniques: Single Equivalent Current Dipole (ECD), Current Distribution (MR-FOCUSS), Beamformer (Borgiotti-Kaplan (BK-BEAM)), and Coherence (ICA-minimum norm). The ECD was performed with 4D Neuroimaging software and the others were all performed in MEG_TOOLS software. Results will be compared to surgical resection if available. Results: Seven of 103 patients have very noisy data that could not be used. Forty-three of 96 patients had 5 or more spikes each identified during MEG analysis. Of the patients who had detectable spikes, all 43 had ECD source localizations. Twenty-seven of 43 patients also had current distribution, and beamformer localizations performed on the interictal spikes as well as Coherence imaging on 10 minutes of spontaneous resting state brain activity. Agreement among three techniques (ECD, BK BEAM and MR-FOCUSS) was found in 19/27 (70%), determined by the localization results having an overlapping component within a region encompassing a 1 cm sphere. Coherence imaging results from this same group of 27 patients that found: concordance in 22/27

6 (82%) with ECD; concordance in 24/27 (89%) with MR-FOCUSS; concordance in 21/27 (78%) with BK BEAM. Conclusions: Advanced MEG techniques (Current distribution, Beamformer, and Coherence) may provide additional interictal epileptiform data, which may be helpful in the decision making process for surgical intervention. Algorithmic Approach to IONM with Case Presentations Where Changes Occurred by Jeff Balzer, PhD, DABNM, FASNM Oct 17th (12 noon Central time, 1pm Eastern, 11am About Jeff: He is an Associate Professor of Neurological Surgery and Neuroscience, Director of the Cerebral Blood Flow Laboratory and Associate Director of Clinical Services, Center for Clinical Neurophysiology at the University of Pittsburgh Medical Center.
