E-113 Lower low-density lipoprotein level increases the risk of delayed parenchymal hematoma following endovascular thrombectomy
ConclusionLDL level <50 mg/dL independently predicted delayed PH following thrombectomy and LDL >100 was shown to be a protective factor, irrespective of statin use. Further study is needed to explore the underlying mechanism and identify the strategies to prevent post-thrombectomy delayed PH among patients with low LDL levels.Disclosures S. Ahn: None. S.

O-027 Contrast density and volume on post-thrombectomy dual-energy head computed tomography predict delayed hemorrhagic transformation
ConclusionMaximum contrast density predicted the occurrence of delayed petechial hemorrhage, while contrast volume predicted the occurrence and volume of delayed parenchymal hematoma. The volume of contrast on DEHCT can serve as a useful predictor of DHT and may have implications for patient management.Abstract O-027 Figure 1Disclosures S. Ahn: None. S. Roth: None. Y. Ko: None. A.

The diagnostic value of quantitative parameters on dual-layer detector-based spectral CT in identifying ischaemic stroke
ConclusionThe study showed the spectral CT would be a potential novel rapid method for identifying AIS. The spectral CT quantitative parameters (Zeff, iodine density values, and iodine–no-water values) can effectively differentiate the ischaemic area from non-ischaemic tissue in stroke patients.

CT after interhospital transfer in acute ischemic stroke: Imaging findings and impact of prior intravenous contrast administration
ConclusionImaging alterations due to residual IV contrast are frequent in clinical practice and render the hyperdense vessel sign largely indetectable. Larger studies are needed to clarify the influence on the association between ASPECTS and ischemic core.

Quantitative Intracerebral Iodine Extravasation in Risk Stratification for Intracranial Hemorrhage in Patients with Acute Ischemic Stroke ADULT BRAIN
CONCLUSIONS: The hemorrhagic transformation predictive power of the normalized iodine concentration ratio is similar to that of the absolute intracerebral iodine concentration in patients with successful recanalization.

A Novel Dual-Energy CT Method for Detection and Differentiation of Intracerebral Hemorrhage From Contrast Extravasation in Stroke Patients After Endovascular Thrombectomy
ConclusionTwinSpiral DECT demonstrates high accuracy and excellent specificity for differentiating ICH from CS in patients after mechanical thrombectomy due to acute ischemic stroke, and improves inter-reader agreement for detecting ICH compared to the standard mixed images.

E-007 Immediate post-thrombectomy dual-energy CT virtual non-contrast imaging for final infarct prediction
ConclusionsImmediate post-thrombectomy DECT with VNC post-processing may more accurately visualize infarcted tissue and aid in prognostication and guiding treatment decisions despite suffering from low inter-rater agreement. Further larger scale studies are warranted.Disclosures C. Kim: None. S. Moghimi: None. A. Rohr: None. F.

Hyperacute Incidental Late Myocardial Enhancement in Ischemic Stroke Using Chest Spectral CT: Relationship with Etiology
CONCLUSIONS: In this study, hyperacute cardiac imaging of AIS with DESCT identified a high prevalence of incidental cardiac disease predominantly involving LIE of ischemic etiology and mostly not related to the stroke etiology.PMID:35345260 | DOI:10.31083/j.rcm2303093
