The Application of a Water Filter to Reduce Radiation during Bone Mineral Densitometry (BMD)


In order to provide a set of basic data that can help to minimize the radiation during bone mineral densitometry and to acquire an optimal image for diagnosis, a water filter was used with a glass dosimeter to acquire an image, and the T-score and Z-score between the image and the radiation amount were measured.Radiation amount was 18+-0.36 µGy for the lens, 17+-0.42 µGy for the thyroid, 18+-0.33 µGy for the breasts, 19+-0.41 µGy for the heart and 18+-0.35 µGy for the reproductive organs. When the water filter was applied by 1cm, 2cm, 3cm, 4cm and 5cm, the radiation decreased by 11.1%. The acquisition of the same T-score and Z score before and after the application of a water filter was to 1cm and for 2cm or more; the same values for T-score and Z-score could not be acquired.The results are expected to provide a basic set of data in forecasting the application of water filters during BMD and determining the test method, leading to reduced radiation.
