Real-Time DMSA-SPECT/US Fusion Imaging Revealing Nonscarring Loss of Function After Pyelonephritis

Using real-time SPECT/US fusion imaging, the localization of an uptake defect in DMSA scan could be identified unambiguously after being uncertain in ultrasound alone. Thereby, a localized functional loss, due to history of pyelonephritis, without scarring, but reduced cortical thickness could be verified. DMSA-SPECT/US primarily demonstrates its utility in depiction of renal pathologies and may be a descriptive tool in equivocal constellation of findings.
