Analysis of Tc99m MDP Radiopharmaceuticals in the Spinal Areas of Breast Cancer Patients

The aim of this study was to obtain doses in the spine breast cancer patients. This dose is very important pharmacy determine distribution drugs body's organs, especially spine. data came from results bone scintigraphy examinations which had known value injection and percentage absorption research conducted by simulating biological half-life values for 3 hours, 4 5 6 7 hours find total will produce a decay constant that be used calculating spinal dose. obtained were lowest mean 0.680 ± 0.160 mCi when highest (biological hours) largest 1.011 0.238 hours). In spine, thoracic region area with because it located closest organs (breast cancer) so experience damage/metastasis. Then Tc99m MDP radiopharmaceutical absorbed into higher. By half-life, hoped we can exact
