What is tc99m DMSA used for?
Tc-99m DMSA has been used in renal imaging to estimate the functional renal mass and relative renal function, especially in pediatric patients with urinary tract infection3–5).
What is the normal relative function of kidney?
The mean relative renal functions measured with 99mTc-DTPA and 99mTc-DMSA were 51.58 ± 14. 95 and 51.96 ± 14.99 for the right kidney, 47.87 ± 15.27 and 47.94 ± 15.17% for the left kidney, respectively.
What is DMSA renogram?
A DMSA renal scan is a diagnostic imaging exam that evaluates the function, size, shape, and position of the kidneys and detects scarring caused by frequent infections. Technetium-99m DSMA (dimercapto succinic acid) is a radioisotope that is injected into your child’s veins through an IV prior to the scan.
What is tc99m DTPA?
Tc-99m DTPA (diethylene-triamine-pentaacetate) is one of the technetium radiopharmaceuticals used in renal imaging and primarily used to measure the glomerular filtration rate (GFR).
Is GFR 120 normal?
According to the National Kidney Foundation, normal results range from 90 to 120 mL/min/1.73 m2. Older people will have lower than normal GFR levels, because GFR decreases with age. Normal value ranges may vary slightly among different laboratories.
What does a renogram show?
A renogram is a nuclear medicine test of the kidneys. It can be used to see how well each kidney is working and whether urine passes on into the bladder without obstruction.
Is DMSA scan necessary?
Ultrasound during acute infection is recommended only for children with atypical UTI, and it should be performed within 6 weeks for those with recurrent UTI. In both cases, it is necessary to perform a DMSA scan 4–6 months after acute infection [7].
What is DTPA used for?
Like the more common EDTA, DTPA is predominantly used as chelating agent for complexing and sequestering metal ions. DTPA has been considered for treatment of radioactive materials such as plutonium, americium, and other actinides. In theory, these complexes are more apt to be eliminated in urine.
What is a normal GFR by age?
In adults, the normal eGFR number is more than 90. eGFR declines with age, even in people without kidney disease….eGFR gets lower as we age. (even when you don’t have kidney disease)
| Age (years) | Average eGFR |
|---|---|
| 20–29 | 116 |
| 30–39 | 107 |
| 40–49 | 99 |
| 50–59 | 93 |
What is a good GFR level?
A GFR of 60 or higher is in the normal range. A GFR below 60 may mean kidney disease. A GFR of 15 or lower may mean kidney failure.
