Quantitative Ultrashort Echo Time (UTE) Magnetic Resonance Imaging of Bone: An Update

Frontiers in Endocrinology, 2020
Bone possesses a highly complex hierarchical structure comprised of mineral (~45% by volume), organic matrix (~35%) and water (~20%). Water exists in bone in two forms: as bound water (BW), which is bound to bone mineral and organic matrix, or as pore ...

Structure-function relationships at the human spinal disc-vertebra interface. [PDF]

, 2018
Damage at the intervertebral disc-vertebra interface associates with back pain and disc herniation. However, the structural and biomechanical properties of the disc-vertebra interface remain underexplored.

ULTRASHORT TIME ECHO MRI SEQUENCE TO QUANTIFY VERTEBRAL BONE MORPHOLOGY IN YOUNG ADULTS

Current Directions in Biomedical Engineering
While MRI is the modality of choice for soft tissue imaging, its ability to visualize bone structures remains limited. In contrast, CT provides superior bone imaging but involves ionizing radiation, making it suboptimal for longitudinal studies in ...

An in vivo imaging study of fascia thickness and muscle volume in the lower limb of healthy adult humans

Computer Methods in Biomechanics and Biomedical Engineering: Imaging & Visualization
Fascia is a connective tissue that influences movement and may play roles in muscle force transmission, pain sensation, and lymphatic function. To date, 3D imaging of fascia using MRI has not been achieved due to short T2* times of collagen-rich fascia ...

Estimation of trabecular bone parameters in children from multisequence MRI using texture-based regression [PDF]

, 2016
PURPOSE: This paper presents a statistical approach for the prediction of trabecular bone parameters from low-resolution multisequence magnetic resonance imaging (MRI) in children, thus addressing the limitations of high-resolution modalities such as HR ...

Quantitative contrast‐enhanced MRI with superparamagnetic nanoparticles using ultrashort time‐to‐echo pulse sequences [PDF]

Magnetic Resonance in Medicine, 2014
PurposeConventional MRI using contrast agents is semiquantitative because it is inherently sensitive to extravoxular susceptibility artifacts, field inhomogeneity, partial voluming, perivascular effects, and motion/flow artifacts. Herein we demonstrate a quantitative contrast‐enhanced MRI technique using ultrashort time‐to‐echo pulse sequences for ...

Estimation of Trabecular Bone Volume with Dual-Echo Ultrashort Echo Time (UTE) Magnetic Resonance Imaging (MRI) Significantly Correlates with High-Resolution Computed Tomography (CT)

Journal of Imaging
Trabecular bone architecture has important implications for the mechanical strength of bone. Trabecular elements appear as signal void when imaged utilizing conventional magnetic resonance imaging (MRI) sequences.
