Question

Quizplus · Accepted Answer

Quantitative ultrasound is a more economical and convenient alternative to DXA scanning for assessing bone health. It can be performed using a portable device and does not expose the patient to ionizing radiation. However, it is not as accurate as DXA scanning and is commonly used to analyze the heel or the patella, not the forearm. It measures the speed of sound waves passing through bone rather than the attenuation of sound energy.
