No, the correct
statement is:
Ultrasonometers
that are used to measure a patient's bone density typically measure the
density of the patient's heel. That is because its bone is similar to
that found in the spine and hip where most osteoporotic fractures occur.
The other statements
were FALSE because:
Trabecular
bone
is lost MORE than cortical bone. It has a high surface-to-volume
ratio and iis usually the first choice for screening, so consequently sites
which are highly trabeculated such as the spine and hip are usually scanned
since they will provide better information on bone loss than in sites such
as the forearm.
If
a T-score from a bone density test is a negative number, that indicates
that bone loss HAS occurred. The more negative a number is, the greater
the risk of fracture.
A
diagnosis of osteoporosis is made when a T-score is negative 2.5 (-2.5).
