... and Achilles, we estimate that the load increased by a factor of 5. Second, the plantaris tendon is small relative to the in-plane MRI resolution of 100 × 140 μm. We estimated the CSA uncertainty to be ± 0.05 mm 2 based on a circular area and a precision of ± 0.5 voxels (±60 μm). This uncertainty...

...), and the posterior region (PR) (Figs. 2( c ) – 2( e ) ). Displacements of the medial meniscus and femoral condyles in the intact, tear, and repair conditions were measured from the MRI images relative to the intact low load position. First, the intact low load image was resliced into the scanner RAS+ (right...

..., but the mechanical changes that occur in this ligament with spinal degeneration are unknown. Additionally, the highly nonlinear, heterogeneous, and anisotropic nature of the facet capsular ligament makes understanding mechanical changes more difficult. Clinically, magnetic resonance imaging (MRI)-based signs...

...-PCMR data were acquired in the aortas of healthy men (n = 12) and women (n = 15) and time-averaged WSS (TAWSS) was compared. Agreement was observed when comparing TAWSS between CFD and the PCMR flow-based method with a correlation coefficient of 0.88 (CFD: 15.0 ± 1.9 versus MRI: 13.5 ± 2.4 dyn/cm 2...

... a stiffness distribution through the thrombus thickness. In this work, we use magnetic resonance imaging (MRI) to delineate the heterogeneous composition of ILT in 7 AAAs and perform patient–specific finite element analysis under multiple conditions of ILT layer stiffness disparity. We find that explicit...

.... In the descending aorta there is general agreement in RRT patterns across different mice, which generally agree well with the average mouse, and is true for both geometries derived from MRI and CT. The patterns are consistent enough to lead one to conclude that there are areas of elevated RRT on the inner curvature...

... information is needed about how the constituent tissues of the cord (i.e., gray and white matter) respond to injurious stimuli. To address this limitation, we developed a novel magnetic resonance imaging (MRI)-compatible test apparatus that can impose either a contusion-type or dislocation-type acute cervical...

Although MR-Tagging was used in this work, the gating method presented here could be applied to any Cardiac MRI technique used on animals when the LV pressure is available. This work was supported in part...

The use of the contralateral-knee for size matching is problematic due to economic and practical reasons. Hence, there are significant...

We developed and applied a new technique to measure spatial and directional variations in surface growth from longitudinal magnetic resonance imaging (MRI) studies of a single animal or human subject.

... and sonication times between 20 s and 40 s. It was found that histology consistently yielded lower lesion volumes than the other two methods, and the calculated values were below magnetic resonance imaging (MRI) at high applied energies. Still, the three methods agreed with each other to within a ± 10...
