PHYS-473 / 3 credits
Teacher(s): Cudalbu Cristina Ramona, Lanz Bernard
Language: English
Withdrawal: It is not allowed to withdraw from this subject after the registration deadline.
Summary
The goal of this course is to teach students how to perform basic MRI and MRS experiments in-vivo and ex-vivo directly on preclinical horizontal ultra-high field MRI systems.
Content
Main topics addressed in the course:
1. Introduction to MRI: Nuclear spin and magnetic moment, nmr-active nuclei/isotopes, macroscopic magnetization, classical description of magnetic resonance, FID, spin echo, gradient echo signal acquisition.
2. Basic anatomical imaging and contrast: T1, T2 and T2* weighted images, impact of acquisition parameters on image contrast
3. Introduction to advanced MRI and contrast : fast MRI, 3D imaging, volumetry, diffusion MRI, in vivo vs ex vivo imaging, volume vs surface RF coils properties
4. Introduction to Magnetic Resonance Spectroscopy (MRS), data acquisition and processing using MRS4Brain toolbox : 1H metabolites resonance patterns, chemical shift, J-coupling, shimming, MRS localization approaches, water signal suppression, outer volume signal suppression, metabolites quantification.
5. Introduction to Magnetic Resonance Spectroscopic Imaging (MRSI), reconstruction, data acquisition and processing using MRS4Brain toolbox : Basics of spectroscopic imaging, signal encoding for localization, 2D and 3D MRSI, FID vs echo-based MRSI
6. Basic artifacts in MRS and MRI and how to avoid them
7. Data processing: volumetry, DTI, metabolic imaging
Keywords
Magnetic Resonance Imaging (MRI), Magnetic Resonance Spectroscopy (MRS), Brain, ultra high magnetic field, metabolic imaging, brain metabolites, spin physics, processing/quantification,
Learning Prerequisites
Recommended courses
Fundamentals of biomedical imaging - PHYS-438
Important concepts to start the course
NMR, MRI basics
Learning Outcomes
By the end of the course, the student must be able to:
- Understand the physical principles of MRI and MRS during hands on exercises on MRI scanners
- Perform basic MRI and MRS experiments
- Establish MRI and MRS acquisition protocols and understand the impact of the acquisition parameters on image contrast or spectral pattern
- Analyze the results for the acquired data
- Explain the basics of organizing a successful MRS experiment, processing/quantification, image processing, using MRS4Brain toolbox
- Read, analyze and discuss representative scientific papers
- Discover the power of interdisciplinary interaction by working on questions and hands on exercises in groups
Transversal skills
- Use both general and domain specific IT resources and tools
- Communicate effectively with professionals from other disciplines.
- Write a literature review which assesses the state of the art.
- Write a scientific or technical report.
Teaching methods
The course will be held every week with alternated sessions of theory and practical teaching:
- - odd sessions (2h): theoretical principles will be explained
- - even sessions (4h): live demos on the scanner will be performed based on the previously explained theoretical principles.
Expected student activities
Active participation in the theoretical courses with questions
Discussions/questions during the live demos
Supervised experimental manipulation of the MRI scanner
Processing of the acquired data
Work in teams for a joint project
Assessment methods
Report/mini project
Supervision
| Office hours | Yes |
| Assistants | Yes |
