Trend Comparison

Assessment of the rate of change in bone mineral density provides the clinician with the best information regard-
ing whether the patient is losing or gaining bone mineral. If previous assessments have been made of the
patient, the current assessment may be compared with past scans to determine the rate of change.

Statistical reasoning is required to interpret scan results. Differences in two serial assessments of a patient
that are close in value could simply be due to random variation. In order to have 95% confidence (p<0.05) that a
change in value represents a change in actual BMD, the change must be at least:

The above equation would be valid for two scans of the same anatomical site on one patient from the same Nor-
land unit. The Coefficients of Variation (C.V.) furnished for each measurement type are valid for subjects hav-
ing well defined bones and non-calcified soft tissue. The following table shows an example of the above
equation using manufacturer C.V. values.

AP Spine Change

Femoral Neck Change

C.V. of 0.9%

a

C.V. of 1.4%

b

If the first value is 1.0 g/cm

2

then change must be

0.025g/cm

2

.

If the first value is 1.0 g/cm

2

then change must be 0.039

g/cm

2

.

Note:

C.V.’s for individual facilities may be different from manufacturer specified C.V.’s, depending

on operator technique and experience.

Precision

Precision

is the degree to which the same value is obtained when a measurement is repeated.

In vivo

precision

in the Norland Bone Densitometer is the degree to which the device presents the same bone mineral value
when a measurement is repeated at the same anatomical site on the same subject.

Factors affecting precision are:

inherent instrumentation errors

operator technique

the

in vivo

nature of the measurement

All precision specifications given in this guide and on the Norland outputs assume:

a properly operating instrument

a stationary scan subject

an experienced operator

proper and consistent positioning and analysis techniques

Precision can be improved by averaging a number of repeated measurements. Then the precision of the mean
value is improved by a factor of the square root of the number of measurements. This technique is used with
phantoms for evaluating instrument accuracy.
