Do I need to take off my shoes for bone density examination during physical examination?

Bone density examination usually requires taking off shoes, which depends on the type of examination equipment.

Dual energy X-ray absorptiometry is the gold standard for bone density examination. When examining the lumbar spine and hip, it is necessary to take off shoes and lie flat on the examination table to avoid interference from the sole material on the measurement results. Some portable ultrasound bone densitometers only require the foot to be placed on the detection probe, and may not require complete removal of shoes but socks. Before inspection, metal objects should be removed and loose clothing should be worn for easy operation. Some hospitals may provide disposable shoe covers as a substitute for taking off shoes, but the thickness of the shoe cover material may still affect the accuracy of the data. Three days before the SEP examination, calcium supplements should be avoided and a normal diet should be maintained, but excessive satiety should be avoided. No special care is required after the examination, and long-term calcium supplementation should be combined with serum vitamin D level testing results. It is recommended that people over the age of 40 undergo regular check ups every 1-2 years, and postmenopausal women and high-risk individuals for osteoporosis can have their check ups shortened to once a year. Daily exposure to sunlight and weight-bearing exercise can enhance bone density. Consuming 300ml of milk or equivalent dairy products daily can help with calcium absorption.
