Diethylenetriamine Pentaacetic Acid Renal Scan (DTPA)

This test is for

Male, Female

Test Preparation

Depending on the area to be imaged, you may be asked to wear a hospital gown at the time of the scan.
Pregnant women should inform their doctor (and x-ray technician) as the radiations may affect the fetus. If needed, precautions can be taken to lower the radiation exposure to the fetus.

Understanding Diethylenetriamine Pentaacetic Acid Renal Scan (DTPA)

What is Diethylenetriamine Pentaacetic Acid Renal Scan (DTPA)?

The Diethylenetriamine Pentaacetic Acid Renal Scan (DTPA) is an imaging test that is used to monitor the functioning of fluid flow across the kidneys. In this, a radioactive material called DTPA (Diethylenetriaminepentacetate) is injected into a vein which reaches the kidneys through blood. The Renal DTPA scan is a unique and efficient way to evaluate kidney function and blood flow. It also helps diagnose any changes in the blood vessels, identify any blockages in the urinary tract, and follow up in the cases of a kidney transplant. Special cameras sensitive to gamma radiation are used to scan the kidneys during the entire process. This scan gives an early and precise diagnosis. The images created can be used to assess the renal functioning and problems associated with it.
