Answer

Early detection of renal scarring is possible with radioisotope scanning with 99m (99m)-technetium dimercaptosuccinic acid (DMSA). This imaging modality is more sensitive than intravenous pyelography (IVP) in detecting renal scars and is considered the criterion standard for diagnosing reflux nephropathy, if present.
