Advances in mechanical assessments of in vivo human lumbar spine tissues with noninvasive imaging techniques

npj Biomedical Innovations
Low back pain (LBP) is the leading cause of disability worldwide, yet clinical imaging remains largely limited to anatomical assessment, providing little insight into the spinal tissue mechanics underlying most idiopathic cases.

Mechanical properties of the in vivo adolescent human brain

Developmental Cognitive Neuroscience, 2018
Viscoelastic mechanical properties of the in vivo human brain, measured noninvasively with magnetic resonance elastography (MRE), have recently been shown to be affected by aging and neurological disease, as well as relate to performance on cognitive ...

Non-invasive characterization of intracranial tumors by magnetic resonance elastography

New Journal of Physics, 2013
Presurgical, non-invasive methods of differentiating brain tumors have remained unsatisfactory even for specialized academic hospitals. Despite major advances in clinical and neuroradiological diagnostic techniques, the majority of neurooncology patients

High spatial and temporal resolution measurement of mechanical properties in hydrogels by non-contact laser excitation

AIP Advances, 2016
Gels have received increased attention as potential materials for biological materials because they can exhibit similar mechanical properties. One obstacle for using gels is that their mechanical properties are significantly altered by defects, such as ...

Quality Assurance of Point and 2D Shear Wave Elastography through the Establishment of Baseline Data Using Phantoms

Sensors
Ultrasound elastography has been available on most modern systems; however, the implementation of quality processes tends to be ad hoc. It is essential for a medical physicist to benchmark elastography measurements on each system and track them over time,
