13:30		0918. Advanced MR vascular Fingerprinting View Presentation Video M. Marçal, T. Coudert, A. Delphin, A. Barrier, E. L. Barbier, B. Lemasson, T. Christen Univ. Grenoble Alpes, INSERM U1216, Grenoble Institut Neurosciences, GIN, Grenoble, France Impact: By combining realistic 3D voxel generation and the MRvF technique, we can achieve a detailed depiction of brain microvascular parameters, potentially improving our understanding of the brain and treatment of brain lesions.
13:42		0919. Improved Liver T1, T2, T2, and PDFF Mapping at 0.55T Using Rosette MRF with Optimized Sequence Design and Deep Image Reconstruction View Presentation Video T. Griesler, E. Cummings, G. Cruz, M. Davenport, H. Hussain, J. Hamilton, N. Seiberlich University of Michigan, Ann Arbor, United States Impact:* Sequence optimization and DIP reconstruction improved the precision of quantitative liver imaging with MRF at 0.55T, potentially enabling liver health assessment in patients who cannot be scanned on higher-field MRI due to accessibility, implantable device, or body size restrictions.
13:54		0920. Spin-lock based Magnetic Resonance Fingerprinting enables characterization of magnetic waveforms via spectral matching of rotary excitation View Presentation Video M. Gram, P. Albertova, T. Griesler, P. Dawood, J. Stebani, M. Blaimer, N. Seiberlich, P. Jakob, P. Nordbeck University Hospital Würzburg , Würzburg , Germany Impact: This study progresses the research and understanding of spin-lock-based magnetic field detection. Magnetic waveforms were characterized by combining concepts from Magnetic Resonance Fingerprinting and the rotary-excitation effect. This method could pave the way for in vivo characterization of biomagnetic fields.
14:06		0921. Accurate MRF T2 in structured materials at 0.55T using MT-suppressed excitations View Presentation Video Z. Zhu, K. Nayak University of Southern California, Los Angeles, United States Impact: The use of non-selective RF excitations substantially reduces MT effects, which mitigates biases in T2 maps estimated using FISP-MRF. This is essential for the application of MRF at low field strengths in structured materials such as white matter.
14:18		0922. Multi-dimensional MR fingerprinting for combined relaxometry-diffusion parameter mapping of the breast View Presentation Video S. Moinian, Z. Qiu, Y. Chen, D. Ma Case Western Reserve University, Cleveland, United States Impact: We present the first combined relaxometry-diffusion MR fingerprinting framework for breast imaging, paving the way for advancements in predictive breast cancer imaging, including improved capabilities for prediction of treatment response.
14:30		0923. Enabling Rapid Quantitative Multi-Tissue Parameter Mapping for Longitudinal Studies through Accelerated MRF with Deep Learning-Based Priors View Presentation Video Y. Urman, Z. Zhou, K. Setsompop Stanford University, Stanford, United States Impact: This approach enables significantly shorter MRF scans in a longitudinal setting without compromising quality. It should facilitate more frequent monitoring of patients, particularly hard-to-scan groups like pediatric, and open avenues for further reducing scan times in quantitative imaging.
14:42		0924. Free-running Cardiac MRF for Simultaneous T1, T2 Mapping and Cine Imaging at 0.55 T View Presentation Video D. Pedraza, C. Castillo-Passi, K. Kunze, R. Botnar, C. Prieto Institute for Biological and Biomedical Engineering, Pontificia Universidad Católica de Chile, Santiago, Chile Impact: A simultaneous acquisition of T1 and T2 maps, along with cine imaging at 0.55T in a single ~13s scan could provide a more affordable and accessible approach to assess cardiovascular disease.
14:54		0925. Evaluation of MR Fingerprinting for Prostatic Lesion Characterization in the Peripheral Zone with Histopathology from MR-TRUS Fusion Biopsy View Presentation Video Z. Yin, S. Afshari Mirak, D. Futela, C. Flask, L. Kayat Bittencourt, M. Griswold, S. Tirumani, Y. Chen Case Western Reserve University, Cleveland, United States Impact: The results from this study demonstrate the potential role of magnetic resonance fingerprinting as a quantitative imaging tool for differentiating clinically significant prostate cancers to provide critical information and increase confidence in subsequent biopsy decision-making.
15:06		0926. High-resolution quantitative imaging of the inner ear using 3D Magnetic Resonance Fingerprinting View Presentation Video J. Stebani, I. Angelov, P. Dawood, T. Griesler, P. Albertova, T. Kampf, K. Rak, P. Jakob, M. Blaimer, M. Gram University of Würzburg, Würzburg, Germany Impact: High-resolution 3D imaging of the IE with joint morphometry and relaxometry as demonstrated in this preliminary work has the potential to supplant the collection of existing methods and may help to better elucidate IE pathologies with non-shape altering, inflammatory etiologies.
15:18		0927. High-quality Four-dimensional Magnetic Resonance Fingerprinting Reconstruction Using Temporal Low-rank-constrained Motion Compensation View Presentation Video C. Liu, L. Wang, W. Liao, X. Wang, V-f Lee, P. Cao, T. Li, J. Cai The Hong Kong Polytechnic University, Kowloon, Hong Kong Impact: This study offers a new registration approach that leverages the temporal low-rank property of respiratory motion as prior knowledge. This method has the potential to register extremely under-sampled images groupwisely, enhancing motion-resolved reconstruction, including but not limited to 4DMRF reconstruction.
