A clinical trial was made by a single energy X-ray absorptiometry (DTX-100 X-ray Bone Densitometer, Hologic Ltd.) to analyze bone mineral density (BMD) of four parts of the distal part of the forearm: radius, ulna, distal (radius+ulna) and ultra distal. These four areas are found by detecting the point where the distance between the radius and ulna is precisely 8mm.
We measured BMD of the distal forearm of 110 women, who did not have diseases influencing the bone metabolism, in their non-dominant side. We also measured the BMD of the whole body, the anteroposterior (A-P) view of L1-L4 spines and lateral view of L2-L4 spines, using QDR-2000 (Hologic Ltd.), at the same time.
The BMD of the distal forearm measured by the DTX-100 was compared with the BMD of the whole body, the A-P view of L1-L4 spines and lateral view of L2-L4 spines measured by the QDR-2000.
This data revealed a significant correlation between both the BMD of the distal forearm by the DTX-100 and of the whole body, the A-P view of L1-L4 spines and lateral view of L2-L4 spines by the QDR-2000.
The results confirmed that the DTX-100 is a useful diagnostic tool for osteoporosis.
