Diethylenetriamine Pentaacetic Acid (DTPA) and Mercaptoacetyltriglycine (MAG3) renal scans are specialised nuclear medicine imaging tests used in children to evaluate their kidney function, drainage, and blood supply. These imaging scans are most crucial and fundamental in pediatric urology to diagnose and monitor conditions such as hydronephrosis, ureteropelvic junction obstruction (UPJO), vesicoureteral reflux (VUR), and other congenital or acquired urinary tract abnormalities. By providing dynamic images and quantitative data, these scans help doctors understand how well each kidney works and whether urine flows properly from the kidneys into the bladder.
Why is it needed?
A DTPA or MAG3 renal scan is favourably effective in children for:-
Assessing differential renal function (how much each kidney contributes to overall function).
Detecting urinary tract obstructions and determining their severity.
Monitoring post-surgical outcomes after procedures like pyeloplasty.
Evaluating complex cases of urinary tract infections or recurrent hydronephrosis.
Guiding treatment decisions for long-term kidney preservation.
Before the Procedure
Parents get advice from doctors to ensure their child is well-hydrated.
Sometimes, doctors insert a bladder catheter to monitor drainage more accurately.
A mild sedative may be necessary if the child is very young or anxious, to help them remain still during the scan.
During the Procedure
Doctors press a small intravenous (IV) radiotracer injection (DTPA or MAG3) into service.
The child lies on the scanning table while a gamma camera takes images of the kidneys as the tracer moves through them.
Sometimes, a diuretic (like Furosemide) becomes necessary to differentiate between actual obstruction and slow drainage.
The procedure typically lasts 30–45 minutes.
After the Procedure
Your kid/child may return to normal activities immediately.
Parents are encouraged to provide extra fluids to help flush out the tracer.
No long-term side effects are possible, as the radioactive tracer dose is very minimal and safe for children.
Benefits & Risks
Benefits
Provides detailed information about kidney function and drainage.
It helps avoid unnecessary surgery by accurately assessing the severity of obstruction.
Non-invasive and safe, with only a small amount of radiation exposure.
Risks
Minor discomfort from IV injection.
Very low radiation exposure (considered safe in paediatrics).
Rare chance of allergic reaction to the radiotracer.
FAQs on DTPA/MAG3 Renal Scans
Is the scan painful for my child?
The scan itself is not painful, though there may be slight discomfort from the IV insertion.
How much radiation is necessary for the scan?
The radiation exposure is minimal, carefully regulated, and considered safe for children.
Will my child need anaesthesia?
Most children don’t need anaesthesia. Only very young or restless children may be given mild sedation for comfort.
How long does the scan take?
The procedure usually takes about 30–45 minutes.
Can my child eat or drink before the scan?
The doctor may recommend increased fluid intake before the procedure for better accuracy.
What happens if an obstruction occurs?
The pediatric urologist will review the scan results and, depending on the severity, may recommend observation, medication, or surgery.
