DTPA and DMSA scans are nuclear medicine tests used to evaluate kidney function and structure. While DTPA assesses kidney function and urine flow, DMSA detects structural damage and scarring.
Medical imaging has developed over the time as the way doctors diagnose and monitor diseases particularly in the field of nephrology. Two commonly used scans DMSA & DTPA at Ganesh Diagnostic and imaging Centre, the no. 1 diagnostic centre helps identify kidney functions. While both are nuclear medicine scans used to evaluate kidney health. In this blog we will learn more about the DMSA and DTPA scans.
What is DTPA Scan?
DTPA (Diethylenetriamine) is a type of renal scan that helps to evaluate the kidney functions and urine flow. In this a radioactive trace is being used to inject in our body (Technetium-99m DTPA) into a vein. Later it is filtered by the kidney and excreted in the form of urine. A Gamma Camera captures images of this process in a current time.
What are the uses of DTPA Scan?
- Measure glomerular filtration rate (GFR) to identify kidney function.
- Detects kidney obstruction.
- Evaluates renal perfusion.
- Diagnosing kidney transplant rejection.
Procedure of DTPA Scan
- A radioactive DTPA in a small amount will be injected into the vein.
- A gamma camera captures images as the tracer moves through the kidneys.
- Patients may be given Diuretics to check urine flow.
- This test takes about 30-45 minutes.
- The doctor will read the images and write the report.
What does it show?
- Structure and function of kidneys.
- How well your kidneys are functioning.
- This also detects the obstruction or blockages.
What is DMSA Scan?
A DMSA (Dimercaptosuccinic acid) is another nuclear medicine test but this provides detailed images of kidney structures and damages. The Technetium-99m DMSA tracer binds the kidney cells and allows doctors to see the size, shape of kidneys.
Use of a DMSA Scan-
- Detects kidney scars caused by infection.
- Evaluates kidney abnormalities.
- Checks unsymmetry in kidney functions.
- Assessing long term kidney damage.
Procedure of DMSA Scan
- A small amount of radioactive material will be injected in your vein.
- The tracer is injected into your body and absorbed by the kidneys.
- Gamma Camera takes pictures of kidneys.
Key differences between DMSA and DTPA-
- The purpose of DTPA Scan is to measure kidney function and whereas the purpose of DMSA provides detailed images of kidney structures and detects scars.
- In DTPA the radioactive substances Technetium-99m DTPA and in DMSA Technetium-99m DMSA.
- The DTPA usually takes more time than DTPA, DTPA takes around 30-45 and minutes DMSA takes 3-4 hours.
- The DTPA is best for kidney function and obstruction and DMSA is best for kidney damage and scarring.
Which scan is best for you?
- The DTPA scan is recommended when your doctors want to check how well your kidneys are filtering blood.
- If they need to assess kidney damage, scarring or infections, the doctor will suggest you take the DMSA test.
