Dynamic renal scintigraphy shows high agreement with MR urography in evaluating split renal function, suggesting improved assessment for urinary obstruction.
Key Points
MR urography provides a detailed assessment of split renal function and urinary obstruction.
Positive correlations were found between split renal function values from MR urography and scintigraphy (r > 0.9).
Renal transit times showed a sensitivity of 65% and specificity of 83% for detecting urinary obstruction.
The findings indicate that MR urography could complement existing techniques like MAG3 scintigraphy.
