Detection of Renal Injury in Patients with Vesicoureteral Reflux Using Dimercaptosuccinic-Acid (Dmsa) - Single Photon Emission Computed Tomography and Magnetic Resonance Imaging - Comparison with Dmsa-Planar Scintigraphy and Intravenous Pyelography
The value of “Technetium (Tc)-dimercaptosuccinic acid (DMSA) planar renal scintigraphy, DMSA single photon emission computed tomography (SPECT) and magnetic resonance imaging (MRI) for the assessment of renal injury related to vesico-ureterai reflux (VUR) were examined in 60 kidneys of 32 patients (28 bilateral, 4 unilateral) with primary VUR. The results were as follows: 1. Spatial resolution was best in MRI, then DMSA-planar and DMSA-SPECT; 2. For detecting renal injury, DMSA-SPECT (85%) and MRI (83.3%) were better than intravenous pyelography (55%) and DMSA-planar scintigraphy (65%). In conclusion, DMSA-SPECT or MRI should be performed in addition to DMSA-planar and IVP, to detect renal injury due to VUR.
