The purpose of this study is to figure out how uptake counts of technetium (<SUP>99m</SUP>Tc) among radioisotopes in the human body are affected if computed tomography (CT), magnetic resonance imaging (MRI) and isotope examination are performed consecutively. <SUP>99m</SUP>Tc isotope material, iodinated contrast media for CT and paramagnetic contrast media for magnetic resonance (MR) were used as experimental materials. First, <SUP>99m</SUP>Tc was added to 4 cc normal saline in a test tube. Then, 2 cc of CT contrast media such as Iopamidol<SUP>®</SUP> and Dotarem<SUP>®</SUP> were diluted with 2 cc normal saline, and 2cc of MRI contrast media such as Primovist<SUP>®</SUP> and Gadovist<SUP>®</SUP> were diluted with 2 cc normal saline. Each distributed contrast media was a total of 4 cc and included 10m Ci of <SUP>99m</SUP>Tc. A gamma camera, a LEHR (Low energy high resolution) collimator and a pin-hole collimator were used for image acquisition. Image acquisition was repeated a total of 6 times and 120 frames were obtained and uptake counts of <SUP>99m</SUP>Tc were measured (from this procedure). In this study, as a result of measuring the uptake counts of <SUP>99m</SUP>Tc using the LEHR collimator, the uptake counts were less measured in all contrast media than normal saline as a reference. In particular, the lowest uptake counts were measured when Gadovist<SUP>®</SUP>, contrast media for MRI, was used. However, the result of measuring the uptake counts of <SUP>99m</SUP>Tc using the pin-hole collimator showed higher uptake counts in all contrast media, except for Iopamidol<SUP>®</SUP>, than normal saline as a reference. The highest uptake counts were measured particularly when Primovist<SUP>®</SUP>, contrast media for MRI, was used. In performing the gamma camera examination using contrast media and <SUP>99m</SUP>Tc, it is considered significant to check the changes in the uptake counts to improve various diagnosis values.
