Süreyya Çerçi, Harun Süslü, Meltem Özbek Summary This study's purpose is to investigate the impact of the Tc99m-MDP (teknesyum 99m-methylendifosphonate) imaging dose on the bone mineral intensity (KMY) values determined by the Dual energy X-ray absorption meter (DEXA) method. In 20 patients (12 men, 8 women) lombal vertebra and proximal femur KMY measurements were performed with the Norland XR-46 bone dancithometry. KMY measurements were performed immediately before and 3 hours after the Tc 99m-MDP injection. In this study, no significant difference was found in lombary vertebra, femur neck, femur trocanter and Wards area KMY (p=0.685, p=0. 783, p = 0.413 and p = 0.332, respectively). Keywords: bone mineral intensity, bone sintigraphy, dexa. The effect of Tc 99m-MDP on bone mineral density The aim of this study is to investigate the effect of a diagnostic dose of Tc 99m-MDP on bone mineral density (BMD) measured by Dual Energy X-ray Absorptiometry (DEXA). The lumbar spine and proximal femur bone mineral densities were measured in 20 patients (12 male, 8 female) using Norland XR-46 bone densitometer. BMD estimations were made prior and 3 hours after injection of Tc 99m-MDP. We did not find any significant change in the BMD of the lumbar spine, femur neck, femur trochanter and Ward's area after bone scintigraphy (p=0.685, p=0.783, p=0.413 and p=0.332, respectively). Key words: Bone mineral density, bone scintigraphy, dexa.
