In busy nuclear medicine departments, the F+0 protocol for diuretic renography is routinely used to shorten the acquisition time. The aim of this study was to evaluate the influence of the F+0 protocol on the split renal function (SRF) during a dynamic renal scan using technetium-99m diethylene triamine pentaacetic acid (Tc-DTPA) compared with that using the standard technetium-99m dimercaptosuccinic acid (Tc-DMSA). A total of 102 patients referred for a dynamic renal scan for varied etiologies were divided into two groups: the F+0 group, comprising 53 patients who were injected with furosemide just before Tc-DTPA injection, and the F+10 group, comprising 49 patients who were injected with the diuretic at the 10th minute after radiotracer injection. All patients were also subjected to a static cortical Tc-DMSA scan with geometric quantification of SRF. A highly significant statistical difference (P<0.001) was obtained on comparing the mean value of the difference in SRF calculated using DTPA and DMSA between the F+0 and F+10 groups, being 5.0±2.6 and 1.5±0.6%, respectively. All 49 patients in the F+10 group had a difference in split function of 5% or less, whereas 17/53 patients representing 32.1% of the F+0 group had a difference in SRF of greater than 5%. Early (F+0) furosemide injection before administration of Tc-DTPA has a significant influence on the estimation of SRF of the diseased kidney (either obstructed or functionally impaired) when compared with furosemide injection after standard Tc-DMSA administration. Care should be taken during interpretation of the scan findings when accurate split function is required.
