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.

Machine learning-based identification of symptomatic carotid atherosclerotic plaques with dual-energy computed tomography angiography
CONCLUSION: FF and NID can serve as useful imaging markers of symptomatic carotid plaques. This tree-based machine learning model incorporating both DECT and clinical features could potentially comprise a non-invasive method for identification of symptomatic carotid plaques to guide clinical treatment strategies.PMID:37290153 | DOI:10.1016/j.jstrokecerebrovasdis.2023.107209

The Great Contrast Shortage of 2022 —Lessons learnt in Australia
ConclusionOur findings demonstrate that the IBCM shortage crisis had a very significant impact on the delivery of healthcare. While V/Q scans could (partially) substitute for CTPA studies in suspected pulmonary emboli, there appeared to be no valid alternative for CTNA studies in stroke calls. The unexpected and critical shortage of IBCM forced healthcare professionals to conserve resources, prioritise indications, triage patients based on risk, explore alternate imaging strategies and prepare for similar events recurring in the future.

Research advances in imaging markers for predicting hematoma expansion in intracerebral hemorrhage: a narrative review
ConclusionThe management of ICH presents a significant challenge, and identifying high-risk patients for HE is crucial to improving outcomes. The use of imaging markers for HE prediction can aid in the rapid identification of such patients and may serve as potential targets for anti-HE therapies in the acute phase of ICH. Therefore, further research is needed to establish the reliability and validity of these markers in identifying high-risk patients and guiding appropriate treatment decisions.

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.

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.

Abstract No. 516 Risk of postcontrast acute kidney injury in patients with gastrointestinal (GI) bleeding undergoing computed tomography angiography (CTA) followed by visceral angiography within 24 hours
The use of iodine-based contrast agents may lead to nephropathy, and patients with underlying chronic kidney disease (CKD) are at increased risk for this complication. In a recent study of patients with stroke who underwent CTA followed by cerebral angiography, 9.5% of patients developed postcontrast acute kidney injury.1 The purpose of this study was to assess the risk of postcontrast acute kidney injury in patients with GI bleeding undergoing CTA followed by visceral angiography within 24 hours.

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
