Xiao Department of Radiology, Second Affiliated Hospital of Naval Medical University, shanghai, China Impact: The treatment selection of TAO depends on its activity. FOCUS MUSE DWI exhibited significantly improved performance in the assessment of TAO staging. Therefore, the application of FOCUS MUSE DWI would be beneficial for treatment selection of TAO.
		Computer Number: 99 4066. The robust advantage of 0.55 Tesla MRI on malignant skin tumor diffusion-weighted imaging compared with 1.5 Tesla MRI View Presentation Video K. Xu, J. Qiu, H. Li, W. Li, J. Zhu, X. Wang, K. Zhou, X. Wang Peking University First Hospital, Beijing, China Impact: Compared with 1.5T DWI, 0.55T DWI has great potential in decreasing artifacts and distortion of skin tumor DWI images by reducing the magnetic field nonuniformity caused by the interface between air and soft tissue.
		Computer Number: 100 4067. Diffusion Imaging of Supraspinatus Tendon Using a UTE-Based DW-SSFP Sequence View Presentation Video K-J Jung University of Illinois Urbana-Champaign, Urbana, United States Impact: The muscular tendon of short T2 can be studied using diffusion imaging with a detectible sensitivity for the 3-D volume in 5 min.

		Computer Number: 101 4068. Towards a clinical acquisition protocol for VERDICT MRI in brain tumours View Presentation Video M. Figini, M. Palombo, M. Bailo, D. Alexander, M. Cercignani, A. Castellano, E. Panagiotaki University College London, London, United Kingdom Impact: We have shown that VERDICT-MRI brain tumour microstructure metrics can be estimated from substantially reduced acquisition protocols than in previous publications while maintaining the capability to differentiate tumour types. This is crucial for the clinical translation of this technique.
		Computer Number: 102 4069. Diffusion MRI acquisition methods for post-mortem imaging on a 10.5 T whole-body human MRI scanner View Presentation Video B. Tendler, S. Warrington, M. K. Selim, W. Wu, G. Adriany, E. Auerbach, A. Bratch, H. Farooq, N. Harel, S. Heilbronner, S. Jbabdi, S. Jungst, C. Lenglet, S. Moeller, F. Pestilli, P. Pisharady, K. Ugurbil, M. Waks, E. Yacoub, S. Sotiropoulos, K. Miller, J. Zimmermann University of Oxford, Oxford, United Kingdom Impact: This research investigates acquisition methods to obtain high-quality post-mortem diffusion MRI datasets using a 10.5 T whole-body human MRI scanner. Data acquired using the described methodology provide detailed neuroanatomical information, informing future brain connectivity and in vivo investigations.
		Computer Number: 103 4070. Multi-shot EPI diffusion tensor imaging of the human lumbar spinal cord is sensitive to microstructural tissue changes in multiple sclerosis View Presentation Video A. Cronin, L. Narisetti, G. Sweeney, K. Schilling, S. Stubblefield, C. McKnight, R. Robison, F. Bagnato, S. Sriram, S. Smith, K. O'Grady Vanderbilt University Medical Center, Nashville, United States Impact: Evaluation of multi-shot, reduced field-of-view, 2D-navigated DTI of the lumbar spinal cord of healthy volunteers and multiple sclerosis patients provides a unique way to study tissue heterogeneity, and identifying specific lesion locations is necessary to evaluate disease-related damage.
		Computer Number: 104 4071. Estimate the effects of imaging gradients and gradient miscalibration on the b-matrix using an isotropic diffusion phantom View Presentation Video R. Dong, A. Barnett, J. Derbyshire, C. Pierpaoli National Institutes of Health, Bethesda, United States Impact: Our method can be used to account for the effects of imaging gradients and gradient miscalibration on different scanners and sites and should help harmonizing multi-site diffusion MRI data.
		Computer Number: 105 4072. Simulated Analysis of SNR and SNR efficiency in motion compensated single-slab DWI, multislab, SMSlab and 2D SMS EPI Techniques View Presentation Video W. Zhong, Y. Jiang, H. Guo Tsinghua University, Beijing, China Impact: This research provides valuable insights into the efficiency of motion-compensated single-slab DWI compared to conventional techniques, guiding future 3D DWI developments in diffusion imaging.
		Computer Number: 106 4073. Optimized Maxwell Compensation in Asymmetric Diffusion Encoding Gradient Waveform Design for Tensor‐Valued Diffusion Encoding View Presentation Video E. Dai, G. Wang, G.
