Radionuclide examination is a safe, reliable and noninvasive method of examination. Because some of the radioactive drugs can be glomerular filtration or renal tubular epithelial cells, secretion and excretion, can emit gamma rays, when the drug is introduced into the body, in vitro imaging apparatus can be used to display its morphology and urinary system concentration Poly, secretion and excretion of the entire process, which can be directly observed
