Overview
Advanced NMR and MRI principles linking the physics principles with the engineering requirements/needs and across magnetic field strengths.
This third part follows Part 2 and will include 8 lectures, 1 meet the teachers session, and 1 discussion at the end. The session will be built as follows:
1- System sanity: measuring SNR (characterizing each element in the receive chain)
2- MR Spectroscopy
3- X-nuclei RF coils
4- Quantitative imaging (relaxometry, recap on basics + advanced methods)
5- Meet the teachers
6- Sparce k-space acquisition & reconstruction (non linear etc)
7- Advanced coils - dielectric, B1 mapping techniques
8- Advanced sequences: ZTE, UTE, SWIFT, simultaneous Tx/Rx
9- Discussion

Target Audience
Physicists and Engineers.

Educational Objectives
As a result of attending this course, participants should be able to:
• Describe spatial encoding and how to navigate through k-space;
• Explain how to accelerate scans; and
• Describe the acquisition chain.

07:45		System Sanity: Measuring SNR (Characterizing Each Element in the Receive Chain) Dan Xiao
08:10		MR Spectroscopy View Presentation Video Mor Mishkovsky Impact: MRS enables non-invasive metabolic imaging, offering early insights into disease mechanisms. This talk highlights the principles of thermally polarized and hyperpolarized MRS, their role in metabolic quantification, and the complementarity of different methodologies
08:35		X-Nuclei RF Coils Dennis Klomp
09:00		Quantitative Imaging (Relaxometry, Recap on Basics + Advanced methods) Nicole Seiberlich
09:25		Break & Meet the Teachers
09:55		Sparse k-Space Acquisition & Reconstruction (Non Linear etc.) View Presentation Video Mariya Doneva Impact: This lecture will introduce the basics of sparse k-space acquisition and reconstruction techniques and their application to fast MRI. It will cover the main concepts of using prior knowledge in non-linear reconstruction approaches and discuss some of the challenges of these techniques.
10:20		Passive Radiofrequency Field Correction: Methods & Device Characterization View Presentation Video Wyger Brink Impact: Various passive technologies exist that enable tailoring the radiofrequency field distribution in MRI, ranging from dielectric materials to metamaterials. This talk will cover the underlying principles, design guidelines and validation approaches commonly used.
10:45		Advanced Sequences for short-T2 imaging: ZTE, UTE, SWIFT and others View Presentation Video Joseba Alonso Impact: This lecture is an introduction to the challenges and potential solutions to imaging of tissues or samples with T2 dephasing so fast that the echo amplitudes from regular Spin or Gradient Echo sequences are impractical, as in e.g. musculo-skeletal, lung or dental MRI.
11:10		Panel Discussion and Q&A
