MetriScan uses radiographic absorptiometry (RA) to estimate relative phalangeal bone density of the three middle fingers. With RA a high resolution radiographic image of a patient's phalanges is taken. A computerized analysis is made comparing the intensity of the image with a reference wedge embedded under the hand plate.
Validation
This method was validated in one of the largest epidemiological studies in the bone density field*. Phalangeal bone density testing was performed on 3481 women, who were then followed for sixteen years. The study concluded that phalageal bone densitometry is a significant predictor of future hip fractures.
