You need to have a table of reference values showing the mean (average) and standard deviation (SD) for the age, gender, race, skeletal site, and densitometer measurement units. Converting the BMD to the T-score is like converting the temperature from degrees Fahrenheit to degrees centigrade: The reference BMD and standard deviation (SD) are to a young person instead of a person the same age as the patient.

Whilst identifying complete bones seems relatively simple, fragmentary remains can be surprisingly difficult. Bone density is more than 2.5 SD below the young adult mean, and there have been one or more osteoporotic fractures. Bone density is lower than in others of the same age, sex, and body size. The dielectric coefficient of bone tissue has been demonstrated to be closely interrelated with its mineral density and elastic modulus, which implies that the health status and mechanical performance of bone can be evaluated by assessing its dielectric properties. Efforts are underway to investigate diagnostic modalities that could help identify racehorses at increased risk of fracture; however, features associated with PSB fracture risk are still poorly understood.
