Diagnosis: Normal renal parenchymal imaging study

Full history:

2 year old child being evaluated for renal parenchymal scarring.


0.9 mCi Tc-99m DMSA


Normal study. The left kidney is slightly smaller than the right.


Renal imaging with DMSA can demonstrate evidence of parenchymal scarring due to prior infection, as well as evidence of focal reaction to infection in the setting of pylonephritis.

If the object is to detect renal scarring, the patient must be free of infection for a few months prior to the exam.

When used for the detection of pylonephritis, the sensitivity and specificity have been reported to be better than 95%.
