Abstract: In renal dynamic imaging, shot injection is needed, because the quality of shot injection directly affects the imaging result, therefore, the injection requirements are higher. This article reviews the application of direct injection, three-way injection, indwelling needle injection, intravenous injection and other methods in radionuclide renal dynamic imaging, and analyzes the advantages and disadvantages of various injection methods, to provide reference for improving the success rate of nuclide kidney dynamic pellet injection.
