What is DTPA scan?
The DTPA scan is an imaging test that uses a radiotracer material called Tc99m-DTPA (diethylenetriaminepentacetate) which is injected into a vein and reaches the kidneys through blood and eventually excreted. Special cameras sensitive to gamma radiation are used to scan the kidneys during the entire process and create images of the urinary system to assess its functioning and any disorders associated with it. These images can be used to assess the renal functioning and detect any problems associated with it.
Why is DTPA scan done?
- To evaluate the kidney function and its blood flow
- To diagnose any changes in the blood vessels like narrowing of the arteries of kidneys
- To identify any blockages or other abnormalities in the urinary tract
- To follow up the cases of kidney transplant
