- What is a DRCG scan ?
- An imaging procedure
- Use of radiotracer material and special cameras to generate images of the urinary bladder during its filling up and emptying to assess disorders.
- What does DRCG stand for ?
Direct Radionuclide Cystogram (DRCG) test .
- Why is this test done?
This test is specified by the doctor to evaluate :-
- Functioning of the urinary bladder
- To detect and diagnose the issues of the urinary bladder
- It functions like urinary reflux, infection, distension, or incomplete emptying.
- Detection of vesicoureteric reflux (VUR) in children after UTI (Micturating cystourethrogram(MCUG) is the first preferred test).
- Also helpful in assessing conditions involving the lower urinary tract and following up a case after a kidney transplant.
- Pregnant women should inform the doctor and x-ray technician as the radiation may affect the fetus.
- Children may consume and drink generally before and after the test.
- Retaining good hydration before and after the test helps in bringing better images and flushing out the radiotracer from the body afterwards.
- If your child requires sedation, special instructions will be provided regarding fasting.
- You should carry a doctor’s prescription for the test and related investigations like ultrasound, MCUG etc. on the day of the test.
- Relying on the area to be imaged, you may be asked to wear a hospital gown at the time of the scan.
- Injection of the isotope through the abdominal wall into the bladder, thus preventing catheterization (inserting a tube in the urinary tract) of the patient.
- Bladder is gradually filled and volume relies on expected bladder capacity, which depends on age.
- Then the catheter is removed and images are taken with the gamma camera while the child passes urine.
- Better patient co-operation, and minimal probability of catheter-induced infection.
- Are there any side-effects of these tests?
- Tests involve radiation.
- Yet, a minimum dose of radiotracer established on your child’s height and weight is used, so that the radiation dose is least.
- The radiotracer is totally excreted outside the body in 24 hours.
- During the procedure sterile precautions are taken.
- A prophylactic antibiotic is generally started before a procedure and given for 48 hours after the procedure.
- How is DRCG different from MCUG?
- DRCG is a sensitive investigation for vesicoureteral reflux( VUR).
- It does not give anatomic details as provided by MCUG.
- MCUG is good for initial examination, DRCG may be used for follow up of VUR or screening for VUR in siblings.
- What is the DRCG scan price in Delhi ?
Price range between ₹ 3200 – ₹ 6250 in Delhi.
- What are the advantages of the DRCG scan ?
- More reliable than conventional roentgen graphic techniques.
- Administration of small radiation dose for this technique.
