I recently acquired a state of the art mobile bone mineral density scanner.
The £20,000 DXL Calscan machine is the product of a huge amount of research and development
over a large number of years in Sweden by Demetech AB - one of the worlds leading
manufacturers of bone scanners.
The device has a tremendous track record of reliability and sensitivity in detecting
osteoporosis - and indeed the early stages of low bone minerals (often called osteopenia)
which can lead to the development of fragile bones.
It is important to point out that this uses what is called DEXA (Dual Energy Xray
Absorpitometry) on the ankle. The amount of xray used is about one fiftieth (1/50)
of the amount of natural background radiation we would naturally be exposed to every
day. So this is a very safe test.
Many people confuse this with an ultrasound scan which is also done on the ankle,
but please be aware that the Calscan is far superior in its sensitivity. The National
Osteoporosis Society support using pDEXA as part of a diagnostic process.
