What is a DTPA/EC Renogram?
An EC renogram is a diagnostic imaging test that shows how each kidney works individually. A small amount of radioactive tracer is injected into a vein, and special cameras track how the tracer moves through the kidneys and urinary system.
In simple words, the scan helps doctors see how well the kidneys filter blood and how smoothly urine drains, without the need for surgery or invasive procedures.
Why is the EC Renogram Test Needed?
The EC renogram test is recommended when doctors need detailed information about kidney performance that cannot be obtained through blood tests or ultrasound alone. It helps assess both kidney function and urine flow in real time.
Common Reasons and Key Conditions Assessed
- Evaluation of kidney function in one or both kidneys.
- Detection of urinary tract obstruction.
- Assessment of kidney drainage problems.
- Monitoring kidney health after surgery or transplant.
- Investigation of unexplained flank pain or swelling.
Types of Renogram / Procedure Variations
Renogram studies can be adapted depending on the clinical question and patient condition. The choice of tracer and technique allows precise assessment of kidney function.
- DTPA Renogram: Primarily measures kidney filtration and blood flow.
- EC Renogram: Focuses on tubular function and urine drainage efficiency.
- Diuretic Renogram: Uses medication to assess urinary obstruction.
- Baseline Renogram: Provides an initial reference for future comparison.

Indications for an EC Renogram Test
An EC renogram test may be advised when:
- Doctors need to compare function between the two kidneys.
- Urinary obstruction is suspected.
- Kidney function needs monitoring over time.
- There is concern about reduced kidney drainage.
- Post-surgical or post-transplant evaluation is required.
Who Should Avoid or Delay a Renogram?
A renal scan is safe for most patients, but certain situations require careful consideration.
- Pregnancy should be considered unless the test is deemed essential.
- Severe dehydration affecting scan accuracy.
- Inability to lie still during imaging.
- Recent nuclear medicine tests requiring spacing.
Preparing for the EC Renogram Test
- Review of medical history and kidney-related symptoms.
- Proper hydration before the test unless advised otherwise.
- Temporary adjustment of certain medications if required.
- Removal of metallic objects before imaging.
- Clear explanation of the scan process and duration.
What Happens During the EC Renogram Test Procedure?
The EC renogram test procedure is performed in the nuclear medicine department. A small injection of radioactive tracer is given through a vein, and images are taken as the tracer passes through the kidneys and urinary tract.
Step-by-Step Breakdown
- Positioning comfortably on the imaging table.
- Injection of the tracer into a vein.
- Continuous imaging to track kidney function.
- Possible administration of a diuretic if needed.
- Monitoring throughout the scan.
- Completion once adequate images are obtained.
After the Renogram Test
There is no recovery period after the scan. Patients can return to normal activities immediately. Drinking fluids helps flush the tracer from the body naturally.
The radioactive material used is minimal and safely exits the body within a short time.
Risks & Complications
Renogram tests are considered very safe. Radiation exposure is low and comparable to other diagnostic imaging tests. Rarely, mild discomfort may occur at the injection site. Serious reactions are extremely uncommon.
Benefits of DTPA/EC Renogram
- Accurate assessment of individual kidney function.
- Early detection of urinary obstruction.
- Non-invasive and well tolerated.
- Useful for monitoring kidney health over time.
- Supports informed treatment planning.
What is the Cost of DTPA/EC Renogram at Manipal Hospitals?
