Table 3. Bone Mineral Density Assessment Technique.

Statements	Level of Evidence*	Median Response	n/N (%)1
Where local normative data exists, measure the bone mineral content and areal bone mineral density in the total body minus the cranial bones (headless), and the postero-anterior lumbar spine	1	Agree	17/18 (94.4)
Total hip and proximal femur bone mineral content and areal bone mineral density measurements are not considered a reliable site for measurement due to difficulties with subject positioning	1	Agree	14/17 (82.4)
Z scores should be calculated from raw values for the following:
Age	2	Agree	22/24 (91.7)
Height	2	Agree	23/23 (100)
Bone mineral apparent density (or volumetric bone mass density) adjustment is also recommended where possible	1	Agree	21/21 (100)
The same skeletal sites should be assessed when repeating densitometry measures longitudinally	4	Agree	27/27 (100)
In individuals with spinal rods, the bone mineral content and areal bone mineral density for the lateral distal femur and the total body minus the cranial bones (headless) should be measured	4	Agree	17/17 (100)
To reduce unnecessary movement during bone mineral density scan procedures, calming techniques such as music, the presence of carers/parents, swaddling or sedation may be used	4	Agree	31/31 (100)
Where possible densitometry measurements of lean tissue mass should be assessed	2	Agree	16/17 (94.1)
