Overview
This session will introduce a spectrum of MR spectroscopic techniques, from the basics of clinical spectroscopy to the advanced editing MR spectroscopy methods. Also, the concept of spectroscopic data harmonization and its advantages and challenges will be discussed.

Target Audience
Radiographers, MR technologists, radiologists, clinicians, and scientists interested in learning about the clinical translation of technological advances in MRI, particularly in the fields of MR Spectroscopy.

Educational Objectives
As a result of attending this course, participants should be able to:
- Recall the basic MR spectroscopic sequences that are commonly used in clinical settings;
- Describe the advanced editing MR technique; and
- Explain the concept of data harmonization.

13:45		Clinical MR Spectroscopy View Presentation Video Alexander Lin
14:15		Advanced Spectroscopy: Editing View Presentation Video Ashley Harris Keywords: Contrast mechanisms: Spectroscopy Following from Dr. Lin’s introduction to spectroscopy and spectroscopic imaging, this talk will focus on “edited-MRS”, a method to quantify metabolites that are hidden in a conventional spectrum, in particular GABA and glutathione. The talk will describe the method itself, advancements of this method, along with its utility and challenges in both its application and interpretation. It will also overview some of the recent applications. The goal is to provide an understanding of how edited-MRS works and factors to consider when using this approach and looking at data.
14:45		MR Spectroscopy Data Harmonization View Presentation Video Brenda Bartnik Olson Keywords: Contrast mechanisms: Spectroscopy Magnetic resonance spectroscopy (MRS) is a powerful, quantitative imaging technique to measure brain metabolites for characterizing neurological diseases. Its impact, however, is limited due to small sample sizes and methodological variability. The lack of standardization in data collection and processing makes it challenging to perform multisite studies that support widespread clinical MRS use. This talk will provide an overview of advanced applications of MRS and the technical and biological factors to consider when aggregating data for multisite trials. The goal is to provide novice and experienced technologists with the necessary knowledge for conducting MRS multisite studies.
