New Test for Osteoporosis Fracture Risk
Heel Ultrasound Could Be Alternative to X-Ray Bone Density Testing for Some Patients
Heel Ultrasound vs. Bone Density X-Ray Testing
Thomas Jefferson University Hospital radiology professor Levon Nazarian, MD, tells WebMD that heel ultrasound may represent a safer alternative to bone density X-ray testing for some patients.
"Anytime you can avoid radiation, that is a good thing," he says. "If it turns out that [ultrasound] screening keeps some patients from needing more testing, it could be beneficial."
But National Osteoporosis Foundation Clinical Director Felicia Cosman, MD, sees little need for the ultrasound screening, especially in the U.S.
She says X-ray-based bone density testing remains the single best predictor of risk of hip fracture.
"[X-ray] bone density testing is accessible to just about everyone, except perhaps those living in really rural, remote areas," she says. "And it is widely covered, so cost is not a big issue. In this country, at least, it is difficult to make the argument that people should have other tests."
Cosman says the utilization of bone density testing is high among many at-risk groups in the U.S., but she adds that this is unfortunately not true for those with the highest risk -- elderly people who have had previous hip or spine fractures.
"Many of these patients get treated for their fracture with no follow-up in terms of testing or treatment for osteoporosis," she says. "These are the patients you want to make sure you evaluate and treat."
