Overview
This educational course provides an overview of opportunities and challenges involved in combining other modalities with MRI, with a focus on in-bore systems including EEG, TMS, ultrasound, PET, linac, and motion tracking hardware.

Target Audience
Scientists and clinicians who want to learn about hardware and methods involved in multimodal imaging.

Educational Objectives
As a result of attending this course, participants should be able to:
- Summarize the state-of-the-art technical aspects of multimodal MRI;
- Recognize the challenges and opportunities with multimodal systems and tools that can be combined with MRI; and
- Identify the engineering aspects involved in EEG, TMS, ultrasound, motion tracking, PET, and linacs.

	08:00		Preclinical Simultaneous fMRI & Electrophysiology View the Presentation Seong-Gi Kim Widely used fMRI relies on hemodynamic responses evoked by neural activity. To interpret fMRI as neural activity, it is critical to correlate fMRI and neural activity. Especially, for dynamically changing fMRI response such as resting-state fMRI, electrophysiology should be simultaneously recorded to correlate with fMRI. Conventional electrophysiology measures local field potentials and spiking activity, while calcium-sensitive fiber photometry or optical imaging can measure cell-type-specific neural responses. Implementation of both approaches within the MR environment will be reviewed, and pros and cons of each method will be discussed. Example applications of simultaneous measurements will be shown.
	08:30		Advances in Human Simultaneous fMRI & Electrophysiology View the Presentation Louis Lemieux In this presentation I will give an overview of the state of technology for, and knowledge on, the concurrent acquisition of electrophysiological signals and fMRI data in humans. Emphasis will be placed on the recording of ECG/EKG and EEG (recorded on the scalp and intracranially) during fMRI. Data quality and safety aspects will be discussed, and key applications illustrated.
