Precision error of fan-beam dual X-ray absorptiometry scans at the spine, hip, and forearm.
The current study investigated short-term precision of fan-beam dual X-ray absorptiometry scans using a sample of subjects typically seen in a routine practice. Seventy-two women were scanned twiceExpand

Comparison of pencil-beam and fan-beam DXA systems.
Patients attending a routine bone densitometry clinic were scanned on two different densitometers on the same day using a pencil-beam (Hologic QDR1000W) and fan-beam (Hologic QDR4500W) machine.Expand

Impact of the analysis of a bone density reference range on determination of the T-score.
There are uncertainties concerning the optimal threshold value of bone mineral density (BMD) for the diagnosis of osteoporosis using dual-energy X-ray absorptiometry (DXA). The most widely acceptedExpand
