Scintigraphic radioisotope counting in superior frontal part of cat's brain

Abstract

The aim of recent study was to describe counting the radiopharmaceutical 99m TC-ECD uptake in the left and right superior frontal regions of cat's brain and show the symmetry between of them. One of diagnostic imaging technique is nuclear medicine that is used in animals. Brain scintigraphy is important in nuclear medicine. In this survey, scintigraphy has done in 20 healthy cats and amount of radioactive materials in necessary scans at special regions has counted. Scintigraphic scans are obtained 20 minutes after injection of 2milliCurie, 99mTc- ECD from femoral vein in anaesthetized cats. In this research, we study accumulation of radioisotopes in superior frontal part of brain by drawing regions outlines interest (ROI). Average count of this radioisotope in right and left side superior frontal parts of brain were 38.4±2.70 and 38.2±2.74 Kcount respectively that show the symmetry between of them.
