Can the Unenhanced Phase Be Eliminated From Dual-Phase CT Angiography for Chest Pain? Implications for Diagnostic Accuracy in Acute Aortic Intramural Hematoma

Abstract

The frequency of acute aortic intramural hematoma is similar to that previously reported. The acquisition of unenhanced images during the chest pain dual-phase CTA protocol significantly improves diagnostic accuracy over single-phase CTA.
