Comprehensive Analysis of Relative Pressure Estimation in Type B Aortic Dissection Utilizing 4D-Flow MRI.

Magnetic resonance imaging (MRI) can estimate three-dimensional (3D) time-resolved blood velocity fields using 4D-flow MRI, providing rich relative pressure field information. Clinical alternatives-catheterization and Doppler echocardiography-provide one-dimensional pressure drops. While the accuracy of one-dimensional...

Impact of Aging, Sex, and Hypertension on Aortoiliac Hemodynamics: A 4-Dimensional Flow Magnetic Resonance Imaging Study.

BACKGROUND The impact of aging, sex, and hypertension on the aortoiliac arterial system is poorly characterized. This study aimed to comprehensively evaluate iliac artery hemodynamics and the vascular aging phenotype using 4-dimensional flow magnetic resonance imaging. METHODS In this cross-sectional study, 235 parti...
