X-ray imaging has been routinely used for bone growth diagnosis purpose. Hand has been the part of choice for X-ray imaging due to its high bone parts count and relatively low radiation requirement. Traditionally, bone age estimation has been performed by referencing atlases of images of hand ...
BoneXpert software automatically measures bone age from a child's hand X-ray according to the Greulich-Pyle and Tanner-Whitehouse methods.
Conclusion: This topic X-ray image based on the hand bones, computer vision, machine learning to extract the relevant'methods, pretreatment and segmentation of X-ray images of the hand bones, characterized by automatic assessment of bone age, lack the core image of the sample problem....
It is of vast significance to assess the bone age of hand radiographs automatically in pediatric radiology and legal medicine. In the literature, many papers focus on improving the assessment accuracy but neglecting the existence of poor-quality X-ray images. However, in real medical scenarios, ...
Objective:To explore the X-ray sign of bone age and improve the adult height of girls with idiopathic true precocious puberty.Methods:165 girls with idiopathic true precocious puberty were divided into 3 types:rapidly progressive growth,slowly progressive growth and retarded growth,X-ray sign of le...
Longitudinal analysis of body weight showed no differences between genotypes in female mice up to 13 month of age (Fig.1D). On the other hand, Panx1ΔOtmice exhibited higher total BMD (5.5%) at 12 months of age, compared to age- and sex-matched Panx1fl/fllittermate mice. Femoral BMD...
A definition of increased HBL adjusted for age- and sex-related bone loss is lacking. In this study, we aimed to: 1) establish reference values for normal hand bone mass (bone mineral density measured by digital x-ray radiogrammetry (DXR-BMD)); and 2) examine whether HBL is normalised ...
Bone mainly functions as a supportive framework for the whole body and is the major regulator of calcium homeostasis and hematopoietic function. Recently, an increasing number of studies have characterized the significance of bone as an endocrine organ,
Total and regional bone mineral content (BMC) as well as lean and fat mass were measured in nine male professional tennis players (TPs) and 17 nonactive subjects; dual-energy X-ray absorptiometry (DXA) was used for measuring. The mean (+/-SD) age, body mass, and height were 26 +/-...
Objective In this study we examined racial differences in BMD acquisition with age and anthropometric indices in healthy adolescent Chinese and Mexican females.Methods We measured the BMD of the posteroanterior(PA) lumbar spine,and proximal femur using dual-energy X-ray absorptiometry(DXA) in a tota...
