Calcium DXA: Impact of Calcium Supplements on Lumbar Spine Bone Mineral Density

We, the investigators at the University of Wisconsin, hypothesized that ingesting calcium tablets prior to a spine bone density scan will not affect the bone mineral density as measured by dual energy x-ray absorptiometry (DXA).

About this study

We hypothesized that ingesting calcium tablets prior to a spine bone density scan will not affect the bone mineral density as measured by DXA. To test this, 36 subjects ingested various calcium supplements after a spine DXA scan and were then scanned again 15, 30 and 45 minutes after ingestion. Subsequently a subset of 15 subjects had three spine scans performed for instrument precision and subsequently ingested a calcium tablet with scans 15 and 30 minute intervals after ingestion.
