The appearance of the image on the PA spine DXA study consists mainly of the anterior elements of
the spine.
false
All patients have 5 lumbar vertebrae and the lowest set of ribs on T12.
false
A fractured vertebra will result in an increase in BMD measurement.
true
Mislabeling the vertebrae on a lumbar spine DXA study causes the BMD to be inaccurate.
true
In patients with scoliosis, lowered BMD of the proximal femur has been noted on the side of
convexity.
true
Forearm sites designated by a percentage are based on the location in relation to the overall length of
the radius.
false
DXA auto scan analysis should never be adjusted by the technologist.
false
Improper placement of bone edges outside of the spine will falsely increase BMD.
false
Bone density values obtained by devices made by different manufactures will not be the same.
true
Bone densitometry is considered a quantitative measurement technique.
,true
Average BMD for L1-L4 is reported rather than individual vertebra because accuracy and precision for
contiguous vertebrae is superior to that of individual vertebra.
true
If the percent young adult value for a particular patient is 90%, this means that the patient has lost
10% of their bone density.
false
If a patient has a poor percentage age matched value, a cause other than age or estrogen loss should
be suspected.
true
When compared with DPA, DXA offers improved precision.
true
Insufficient femoral neck rotation results in a decrease in BMD
False
