- Abstract:
- In nuclear medicine, renal scan includes renal dynamic and static imaging.Diuretic renal dynamic imaging is recommended for pediatric hydronephrosis.It evaluates the nature of hydronephrosis while assessing differential renal function.Different radiotracers are utilized for renal dynamic scan of pediatric hydronephrosis.According to age, 99mTc-EC is recommended for children aged under 2 years and 99mTc-DTPA for those aged over 2 years.When analyzing renal function and renogram curve, clinicians should pay attention to various influencing factors.Glomerular filtration rate(GFR) based upon double plasma method is accurate.However, wider clinical applications are difficult.Based upon renal dynamic imaging, many influencing factors for GFR require comprehensive analyses.Renal static imaging is employed for evaluating the extent and severity of pyelonephritis and renal scar.Also renal function may be evaluated.There are fewer influencing factors of renal static imaging.With recent widespread applications of single photon emission computed tomography/computed tomography(SPECT/CT) in nuclear medicine, 99mTc-DMSA SPECT/CT tomography can more accurately assess the kidney function of pediatric hydronephrosis.This review discussed the uses of nuclear medicine renal imaging in evaluating renal function in pediatric hydronephrosis.
