Bone density scanning also known as bone densitometry or dual-energy X-ray absorptiometry (DEXA), is an enhanced form of X-ray technology that is used as a non-invasive bone density test to measure bone loss. It is used to determine body composition because it can aid in measuring the percentage of the body’s lean muscle and fat. The most common purpose of a DEXA scan in Chennai is to evaluate if a person’s bones are weak, about to fracture, or if they have osteoporosis.
When determining if any patient has a low bone density or if the condition gets worsened, a DEXA scan is considered to be more accurate. Unlike an ordinary X-ray, it can spot even minor changes in bone loss. At Vinita Health Hospital, a DEXA scan is most often performed on the hips and the lower spine whereby low-energy x-rays are directed through the bone for measuring its mineral density. An accurate predictor of bone strength is mineral density. The results of this test are used for diagnosing osteoporosis besides assessing an individual’s risk for developing fractures.
