Dose-efficient assessment of trabecular microstructure using ultra-high-resolution photon-counting CT
2022, Zeitschrift fur Medizinische PhysikCitation Excerpt :Nevertheless owing to the small dimensions of trabecular struts, the assessment of trabecular bone microarchitecture in its native 3D milieu is challenging. Typical trabecular thickness and separations at the spine are about 0.14–0.20 mm and 0.5–1.3 mm, respectively [2–5]. Techniques using dedicated high resolution peripheral CT equipment or dedicated imaging protocols devised for clinical CT scanners combined with sophisticated analysis software have been developed that permit evaluation of trabecular bone microstructure and to monitor physiological changes.
Local and global microarchitecture is associated with different features of bone biomechanics
2020, Bone ReportsCitation Excerpt :In addition, Jensen et al. demonstrated that, without changing the overall trabecular bone volume fraction, bone mechanical behavior dramatically varied from a uniform to irregular microarchitectural network (Jensen and Mosekilde, 1990). Therefore, local variations in bone microarchitecture leading to local structural weakness could be considered as a determinant factor for predicting localized failure as reported in the current study (Jensen and Mosekilde, 1990). Consequently, bone mass and global microarchitecture alone should not be considered as the unique indicators of trabecular bone mechanical competence (i.e., stiffness and strength).
A novel mechanical parameter to quantify the microarchitecture effect on apparent modulus of trabecular bone: A computational analysis of ineffective bone mass
2020, BoneCitation Excerpt :Clinically, the BMD overlaps from fracture and non-fracture patients have made a strong request for a more comprehensive bone strength evaluation than BMD. Since the first lattice network model proposed [12], trabecular continuity [15], orientation [13] and connectivity [14,17,18] have been experimentally or clinically demonstrated to be important contributors to bone mechanical competence. Morphological and topological analyzes further explored the relative contribution of trabecular rods and plates to the apparent modulus of trabecular bone [11,16,25–27,30].
