Application of renal radionuclide imaging in the diagnosis and treatment of duplex kidney

Duplex kidney is a common congenital urinary system disease, and its diagnosis mainly relies on conventional imaging methods such as intravenous pyelography, ultrasound, CT, MRI, etc. These methods have their own advantages and disadvantages. Renal radionuclide imaging, with lower radiation dose, is convenient, repeatable, safe and reliable, and it can evaluate the morphological structure and function of kidneys simultaneously, which has great advantages in the diagnosis, clinical decision making, efficacy evaluation and prognostic analysis of duplex kidney. With the rapidly widespread use of SPECT/CT, renal nuclide imaging could complement advantages with other imaging methods and become an important method for the diagnosis and treatment evaluation of duplex kidney. This paper reviews the application of renal radionuclide imaging in the diagnosis and treatment of duplex kidney.
