Overview
In this session we will go through various ways of generating multiple contrasts or biomarkers from single acquisition. These include synthetic MR, MR Fingerprinting, using deep learning to generate synthetic images from another image, as well as multiple diffusion and perfusion biomarkers and multi-organ imaging.

Target Audience
Trainees, Clinicians, and MR physicists.

Educational Objectives
As a result of attending this course, participants should be able to:
• Describe how multiple parameters can be extracted from a single acquisition;
• Describe how to identify contrasts/biomarkers for clinical relevance; and
• Explain how to obtain multiple diffusion/perfusion parameters via different modelling approaches.

08:00		Synthetic MRI and Clinical Applications View Presentation Video Akifumi Hagiwara Impact: Advances in rapid quantification of relaxation rates and proton density now enable clinical use. This talk presents these techniques, the creation of contrast-weighted images (synthetic MRI) using absolute values, and their clinical applications.
08:35		Advances in MR Fingerprinting Jesse Hamilton
09:10		Deep Learning Based Contrast Conversions: Synthetic CT from MRI View Presentation Video Anais Barateau Impact: Key challenges of synthetic CT (sCT) from MRI by deep learning in radiotherapy are the choice of MR sequences, the robustness, and the clinical implementation. sCT from MRI is transforming radiotherapy by improving workflow efficiency while minimizing patient radiation exposure.
09:45		Meet the Teachers
10:15		Single Scan, Multiple Diffusion Parameters View Presentation Video Elizabeth Powell Impact: This talk highlights how diffusion MRI can be utilised for imaging neurofluids, and covers techniques for imaging tissue perfusion, glymphatic system function, and blood-brain barrier integrity.
10:50		Single CA Injection, Multiple Perfusion Parameters View Presentation Video Benjamin Ellingson Impact: This presentation explores advanced techniques for extracting multiple perfusion parameters from a single contrast agent injection in brain tumor imaging.
11:25		Multi Contrast Single Scan for Multi-Organ Applications × Video Permission Withheld Jing Liu Impact: This presentation highlights multi-contrast single scan MRI, improving diagnostic accuracy, reducing scan time, and enhancing patient comfort. It covers techniques like compressed sensing, multi-parametric mapping, and AI, with applications across the brain, heart, and abdomen.
