Abstract:
The previous reports have indicated that both the DMSA scan and the DTPA scan were significantly related with the relative renal function ( RRF) and there was a close relationship between the DMSA scan and the DTPA scan in the evaluation of the RRF We reviewed our experience with 24 cases, in which the DMSA scan and the DTPA scan were performed within 2 weeks from January 1987 to April 1991. The DMSA scan was more reliable than the DTPA scan and the difference of the RRF between right and left side by the DMSA scan was more apparent than that by the DTPA scan. However, in infants, both scans showed the reversed results. Our study suggests that DMSA scan is more reliable than the DTPA scan in the evaluation of the RRF, but both renal scans are inappropriate in infants, especially under the age of 1 months.
