Radio- Reno Gram (Radioisotope Renography ) Renal scintigraphy is an imaging method that uses small amount of radioactive materials called radiotracers, a Gamma camera and a computer to evaluate kidney functions and its anatomy. DTPADTPA/MAG3 the blood flow to the kidneys and function of the kidneys

relative renal functions (RRF)  or (Excretory Function)

DMSA - dimercaptosuccinic acid ( S for Scaring)

DMSA is an ideal agent for the assessment of renal cortex as it binds to the sulfhydryl groups in proximal tubules at the renal cortex with longer retention than other agents. It is a static scan as opposed to dynamic DTPA or MAG3 scans.

for abnormalities such as scarring and infection. It also measures the relative function of each kidney.

99mTc-DMSA may be the primary choice for the evaluation of RRF, but if the glomerular filtration rate (GFR) and renogram curve are required, 99mTc-DTPA can be the obvious selection.
