Volumetric bone mineral density — a potential role in paediatrics

Acta Paediatrica, 1995
The use of areal bone mineral density (aBMD) in paediatric populations has aroused some concern, as it fails to take the age‐related increase in bone thickness into account. We have developed a measure of true bone density, volumetric bone mineral density (vBMD), which is independent of age and height.

Volumetric Density of Triangulated Range Images for Face Recognition

2020
In this paper, a volumetric space representation of 3D range face image has been established for developing a robust 3D face recognition system. A volumetric space has been created on some distinct triangular regions of the 3D range face image. Further, we have constructed 3D voxels corresponding to those regions for developing voxelization-based 3D ...

Volumetric Bone Mineral Density in Patients with Childhood Craniopharyngioma

Experimental and Clinical Endocrinology & Diabetes, 2003
As the overall survival rate is high in patients with craniopharyngioma, the prognosis in survivors depends mainly on late effects. Late effects such as hypogonadism, growth hormone deficiency, glucocorticoid overreplacement and obesity have a strong impact on volumetric bone mineral density (vBMD).

Using Volumetric Breast Density to Quantify the Potential Masking Risk of Mammographic Density

American Journal of Roentgenology, 2017
The purposes of this study were to compare BI-RADS density categories with quantitative volumetric breast density (VBD) for the reporting of mammographic sensitivity and to identify which patient factors are most predictive of a diagnosis of interval cancer of the breast versus screen-detected cancer.This retrospective study included screen-detected ...

Effect of Anorexia Nervosa on Volumetric Bone Mineral Density

Calcified Tissue International
It was widely acknowledged that patients with anorexia nervosa (AN) present a decrease in areal bone mineral density (aBMD), but the effect on bone microarchitecture and other parameters associated with fracture risk have been less well investigated. The two aims of this study were to (i) compare aBMD at various bone sites as determined by DXA, as well

An Alternative Approach to Measuring Volumetric Mammographic Breast Density

2006
The effect on the measurement of volumetric breast density of variations in physical and chemical properties of adipose and fibroglandular tissue reported in a number of studies is investigated using the authors' model of mammographic image formation. This model is developed specifically for the measurement of breast density.

Breasts of intermediate density - volumetric breast density data and estimate of prevalence

2020
Purpose: Breast density depends on the relative amount of fibroglandular tissue (FGT) within the breast. There is a continuum of breast densities seen in population: from those with virtually no FGT – seen as radiolucent on mammography, to those where FGT...
