Differentiation of low-attenuation intracranial hemorrhage and calcification using dual-energy computed tomography in a phantom system

摘要

ObjectivesCalcific and hemorrhagic intracranial lesions with attenuation levels of <100 Hounsfield Units (HU) cannot currently be reliably differentiated by single-energy computed tomography (SECT). The proper differentiation of these lesion types would have a multitude of clinical applications. A phantom model was used to test the ability of dual-energy CT (DECT) to differentiate such lesions.
