“…Interest in public health is increasing due to the drastic increase in cerebrovascular diseases and cancer in the elderly population than in any other age group, as well as the reduced age for the onset of geriatric diseases resulting from environmental changes. Accordingly, many kinds of diagnostic methods have been developing for early detection and diagnosis of disease, especially X-ray, CT, MRI and nuclear medicine tests have been used as a medical high-tech diagnostic method [1][2][3][4].…”

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