• Dual energy CT can help in differentiation of Intraparenchymal hemorrhage from contrast enhancement. • Dual energy CT allows reliable differentiation between frequent blood brain barrier disruption and rare intracerebral hemorrhage immediately after endovascular recanalization therapy. • Dual energy CT helps in avoiding overestimation of SAH after peri-interventional re-bleeding. • Reduction of metallic streak artifacts arising from spinal hardware. • Reduction of radiation dose by 30-50% as compared to single energy CT.  

• Siemens dual energy scanner (SOMATOM) was used for performing the dual energy scans. • Retrospective study of 50 patients with hemorrhages at different sites was performed from January 2012 to December 2013. • Patient age from 35-70 years and both sexes. • All patients underwent single energy non-contrast CT and contrast-enhanced dual- source DECT. • DECT images were post-processed with commercial software, applying a three- material decomposition algorithm for brain hemorrhage followed by obtaining iodine images and virtual non-contrast images and generating combined images that created the impression of 120 kvp images.
