.... In order to evaluate potential dehydration and effect of load history, we measured residual loads after MRI scanning. Residual loads were 295 N±41N at 68 min±4 min after the load was initially locked into the frame (∼65% relaxation from initial load to the end of imaging). These values were not different...

..., 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...

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...

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...

A novel combination of computational and statistical models based on serial magnetic resonance imaging (MRI) was introduced to quantify sensitivity and specificity of mechanical predictors to identify the best candidate for plaque rupture site prediction.

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...

On average, taking account of individual variations, the thickness measurements in MRI were overestimated in thinner ( < 2.5 mm ) regions. The cartilage thicker than 2.5 mm was accurately predicted...
