Commonly used tracers are I-o-iodine uric acid (I-OIH), Tc-DTPA, Tc-EC, Tc-MAG3, etc. and can be processed by computer to obtain the renal kidney time-radiation curve, which can reflect the glomerulus and The filtration rate of renal tubule function and the value of renal effective plasma flow. It is mainly used for diagnosing urinary tract obstruction, and the object of nephrectomy, such as renal tuberculosis, has a non-functioning renal map on one side, which can be used as an indication for surgical resection.
