Objective: We conducted this prospective study to establish the correlation between dual energy x-ray absorptiometry (DXA), quantitative ultrasound (QUS) and single energy x-ray absorptiometry (SXA) and to establish the role of QUS and SXA as a screening tool for osteoporosis.Methods: We carried out measurements of bone mineral density (BMD) of lumbar spine and femoral neck using DXA, QUS of heel using ultrasound densitometer, and BMD of forearm using SXA. We performed all the measurements at the Nuclear Medicine Division of King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia between 2002 and 2004. We obtained the measurements of 437 female adult patients, aged 20-87 years.Results: We expressed all the values as mean +/- SD.
