Bone quality is defined as the sum of the structural and material properties of the trabecular bone. The structural properties of bone refer to the trabecular microstructure. Trabecular or cancellous bone is made up of many interconnected trabeculae which may be composed of narrow rods like trabeculae or the flatter plate-like trabeculae. The more of the thicker plate-like trabeculae present in the structure as compared to the thinner, rod-like trabeculae, the better the quality and strength of the bone. Bone Mineral Density (BMD) measured by Dual Energy X-ray Absorptiometry (DXA), has been used for the diagnosis of osteoporosis and thereby Bone Strength.
The specific part of body mass analysis required for Orthopedics, Nuclear medicine, Geriatrics, Rehabilitation, Neurology, Plastic surgery.The term Body Composition is used to illustrate the different components that, when taken together, make up a person`s body weight. For analysis of body composition, it is often suitable to think of the body as made of two components: fat and non-fat. The non-fat portion is called "fat-free mass" or "lean body mass". However, the body can be taken into different compartment models for body composition assessments. It depends upon the compartment of interest, availability of techniques, technical training of staff, condition of patient/subject and location where the assessment will be done i.e., laboratory/clinic or field / remote site. Body Composition is a tool for diagnosis as it may be significantly altered in many disorders like Anorexia and obesity, Renal failure, Liver disorders: Ascites, Chronic obstructive pulmonary disease, Cancer and AIDS-associated wasting, Burns and trauma, Congestive heart failure, Spinal cord injuries and Osteoporosis.
A method for measuring human body composition using digital images, Body mass index (BMI) is a proxy for obesity that is commonly used in spite of its limitation in estimating body fatness. Trained observers with repeated exposure to different body types can estimate body fat (BF) of individuals compared to criterion methods with reasonable accuracy. Analysis for body composition of a certain line of interest like CT scan required for Neurology, Geriatrics, Orthopedics, Rehabilitation, Medical study
