Overview

Retrospective analysis shows significant differences in DRF quantification in renal scintigraphy methods, suggesting reliable results from 3D assessment.

Key Points

This research compares 3-dimensional and planar methods for quantifying differential renal function in renal scintigraphy.
Retrospective study with 108 patients referred for cortical renal scintigraphy.
DRF measured using SPECT and planar imaging techniques with geometric mean comparison.
Reliability assessed with intraobserver and interobserver analyses using intraclass correlation coefficients.
Significant difference in DRF values between planar and SPECT methods (P < 0.05).
Maximum differences were 40.0% for 99m Tc-glucoheptonate and 13.0% for 99m Tc-DMSA.
High reliability noted for both methods, with intraclass correlation coefficients exceeding 0.9.
