Altes University of Missouri-Columbia, Columbia, United States Impact: TagGen enables 10-fold accelerated, high-quality cardiac MR tagging, making accurate myocardial deformation assessment feasible within clinical workflows with greatly reduced scan time. This advancement broadens MR tagging accessibility and may enhance the detection of subtle heart motion abnormalities.
		Computer Number: 9 3665. Additive effects of vertebral artery geometry deformation on VBA plaque vulnerability in hypertension: an HR-VWI study J. Xia, C. Zhang, L. Mei, J. Lyu, X. Qu the Second Hospital of Dalian Medical University, Dalian, China Impact: Our findings concerning the additive effects of vertebral artery geometry deformation on vulnerable plaques in the basilar artery of hypertensive patients provide a basis for improved clinical management and comorbidity treatment strategies.
