The following question has been sent by Dr. Ravi Mahal, Radiologist, Boca Radiology Group, USA:
We have been using the DECT for Urinary stone composition for the past 6 months. Recently I had a case where a patient had 2 stones of different compositions; a right uric acid stone and a left CaOx stone. The composition was \’confirmed\’ with HU Overlay values using the syNgro software. Was wondering if this is even physiologically possible? Have you run into patients with 2 different stone compositions?
Savvas Nicolaou, MD, University of British Columbia, Canada:
Yes it is possible to have stones with different composition.
We have seen the same stone have a combination of calcium and uric acid that was confirmed pathologically
