1.A dual-energy X-ray absorptiometry scan (DXA), or bone density scan, is a special type of X-ray that measures bone mineral density (BMD). It provides information about bone strength or fragility and the risk of fractures or broken bones. The higher the density, generally, the lower the risk of fracture
2. Color Doppler an ultrasound technique to evaluate blood vessels. Using the Doppler principle of changing pitch with velocity, ultrasound waves that reflect from the red blood corpuscles in t
