Evaluation of Bone Length Measurement

Not Applicable

Completed

• Conditions: Bone Calcification; Osteoporosis
• Interventions: Procedure: Lunar iXDA scan

• Registration Number: NCT02165527
• Lead Sponsor: University of Michigan

Brief Summary

The purpose of this study is to determine if Lunar iXDA scanning with the use of a computer software program can make accurate measurements of the length of leg bones compared to conventional x-rays.

Detailed Description

The investigators would like to see how well the calculation of bone length using Lunar iDxa compares to conventional x-ray since the Lunar iXDA exposed patients to less radiation than conventional x-rays.

Arm && Interventions

Group	Intervention	Description
x-ray with iXDA scan	Lunar iXDA scan	Tota body scan taken by the Lunar iXDA. During the scan, subject will be asked to lay on their back. Following the Lunar iDXA scan, the computer of the Luna iXDA will calculate bone length. The calculation of bone length will be compared to a calculation from the subject's conventional x-ray to determine accuracy.

Primary Outcome Measures

Name	Time	Method
Leg (Femur and Tibia) bone length measurement in centimeters using iDXA	scan time is 8 minutes	Lunar iXDA computer will calculate the bone length following a total body scan taken by the Lunar iDXA and compare results from conventional x-ray to determine accuracy.
