Alara Metriscan Bone Densitometer (BMD) Bone Density Machine
MetriScan lets the primary care physician screen patients' bone mineral density (BMD) during a routine office exam. This type of test typically requires a visit to the hospital imaging center for a Central DEXA examination.
Physicians now have a front line diagnostic tool that will help them identify patients who may have low BMD and be at risk for osteoporotic fractures. Using a one minute procedure that scans the patient's hand, physicians can assess osteoporosis risk. This is critically important today, as osteoporosis was recently determined to be significantly underdiagnosed Specifications:
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.
