Overview
This course with cover the theoretical foundations and applications of imaging modalities that make use of non-standard contrast mechanisms, such as elastography (MRE), magnetic susceptibility (QSM and SWI), electric conductivity (MR EPT), functional susceptibility changes (fQSM), and ultrashort TE (UTE) and zero TE (ZTE) sequences.

Target Audience
This course is designed for scientists and clinicians who are interested in understanding, developing, or applying imaging techniques that make use of non-standard contrast mechanisms, such as elastography (MRE), magnetic susceptibility (QSM), and electric conductivity (MR EPT). The course is also focused on those interested in functional imaging based on changes in susceptibility (fQSM) or those wishing to use ultrashort TE (UTE) and zero TE (ZTE) sequences to scan challenging structures due to their rapid spin-spin relaxation.

Educational Objectives
As a result of attending this course, participants should be able to:
- Explain the acquisition and processing methods for different MRI approaches with non-traditional contrast mechanisms;
- Discuss the pros and cons of each method; and
- Identify different areas of applications for each method.

07:00		Novel/Alternative Contrast Mechanisms for Functional MRI: fQSM View Presentation Video Pinar Özbay Keywords: Contrast mechanisms: fMRI, Contrast mechanisms: Susceptibility, Neuro: Brain function In recent years, there has been growing interest in fMRI techniques that utilize information beyond signal-magnitude variations, such as time-course phase and susceptibility data. This talk aims to investigate the reasons behind the BOLD response in phase and susceptibility maps, which complement magnitude data, and to explore the effects of processing steps on this data. The talk also delves into the dynamics of phase and magnitude brain activity during both rest and task conditions, while considering physiological and behavioral factors.
07:30		Novel/Alternative Contrast Mechanisms for Functional MRI: Diffusion-Based fMRI/VASO View Presentation Video Noam Shemesh Keywords: Neuro: Brain function This lecture will focus on VASO and diffusion-fMRI as methods imparting enhanced specificity on the funtional MRI signal.
