Comparison of Tc-99m DMSA Renal Planar Scan and SPECT for Detection of Cortical Defects in Infants with Suspected Acute Pyelonephritis.

Tc-99m DMSA renal SPECT showed a higher detection rate, compared with planar scan, for renal cortical defects in infants with suspected acute pyelonephritis. The study results suggest that, compared with planar scan, Tc-99m DMSA SPECT can detect small cortical defects with greater sensitivity.
