AI Article Synopsis
- Dual-energy computed tomography (DECT) is gaining traction in neuroimaging, particularly for differentiating types of brain hemorrhage after certain medical procedures.
- The effectiveness of DECT in assessing brain ischemia in patients who have undergone resuscitation with iodinated contrast has not been extensively studied.
- A specific case illustrates how DECT clarified hyperattenuation in various brain regions in a comatose patient who experienced a cardiac arrest due to a massive pulmonary embolism.
Article Abstract
Applications of dual-energy computed tomography and virtual non-contrast technique in neuroimaging are still emerging. While the role of DECT in differentiating parenchymal hemorrhage and contrast media after mechanical revascularization is well recognized, the value of DECT in evaluation of brain ischemia in post resuscitation patients who have received intravenous (IV) iodinated contrast is not well documented. We present a challenging case where DECT helped explain hyperattenuation in cortical grey matter and deep grey nuclei as well as cerebellar hemispheres in a comatose patient post cardiac arrest following massive pulmonary embolism.
