Dual-energy X-ray absorptiometry

（重定向自DEXA）

DEXA assessment of bone mineral density of the femoral neck (A) and the lumbar spine (B): T scores of - 4.2 and - 4.3 were found at the hip (A) and lumbar spine (B), respectively in a 53-year-old male patient affected with Fabry disease.

Dual-energy X-ray absorptiometry (DXA, previously DEXA) is a means of measuring bone mineral density (BMD). Two X-ray beams, with different energy levels, are aimed at the patient's bones. When soft tissue absorption is subtracted out, the BMD can be determined from the absorption of each beam by bone. Dual-energy X-ray absorptiometry is the most widely used and most thoroughly studied bone density measurement technology.

单词	DEXA
释义	DEXA 原声例句 Osmosis-肌骨 Osteoporosis is usually diagnosed with a dual-energy X-ray absorptiometry or DEXA scan which tests for bone density. 骨质疏松的诊断一般利用双能X线吸收法（DEXA扫描）测量患者的骨密度来完成。 Osmosis-肌骨 Diagnosis is done with a dual-energy X-ray absorptiometry or DEXA scan, where a T score equal to or less than -2.5 equals osteoporosis. 诊断是借助双能X线吸收法（DEXA扫描）完成，当检验结果中T分数小于等于-2.5时，可确诊为骨质疏松。英语百科 Dual-energy X-ray absorptiometry （重定向自DEXA） Dual-energy X-ray absorptiometry (DXA, previously DEXA) is a means of measuring bone mineral density (BMD).
