Accreditation Guidelines for Bone Densitometry	[ TABLE OF CONTENTS ]

APPENDIX 4 - Measurement of short term precision in-vivo

With the approval of an appropriate independent body, which satisfies the requirements of the relevant legislator, a minimum of 28 previously scanned volunteers shall be re-scanned, with informed consent, as outlined in Appendix 2. Repositioning between scans is essential (the patient shall alight completely from the bed between scans). For any number of patients (N), with duplicate scans on the same day, the precision of the measurement, expressed as the co-efficient of variation (CV), is calculated as shown:
