Diffusion-weighted MRI of ischemic stroke at 3T: Value of synthetic b-values.
CONCLUSION: Synthetic images at b = 1000 and 1500 s mm-2 and acquired DWI images at b = 2000 s mm-2 may be of clinical value due to improved lesion conspicuity. ADVANCES IN KNOWLEDGE: Synthetic b-values enable improved lesion conspicuity for DWI of ischemic stroke. PMID: 33596102 [PubMed - as supplied by publisher]

Association of dissection features and primary collateral circulation with ischemic stroke in patients with spontaneous internal carotid artery dissection: Evaluated using vessel Wall-MRI and MRA
CONCLUSIONS: Both the poor primary collateral circulation and severe stenosis may play important role in occurrence of ischemic stroke for spontaneous ICAD patients and good primary collateral circulation can help to reduce the incidence of infarction.ADVANCES IN KNOWLEDGE: ICAD is one of the major causes of ischemic stroke. Early evaluation of the status of the Circle of Willis in ICAD patients by MRI may help to make treatment strategies and improve clinical outcome.PMID:35816551 | DOI:10.1259/bjr.20210845

Imaging assessment of acute ischaemic stroke - a review of radiological methods.
Abstract Acute ischaemic stroke is the second largest cause of death worldwide and a cause of major physical and psychological morbidity. Current evidence based treatment includes intravenous thrombolysis (IVT) and mechanical thrombectomy (MT), both requiring careful patient selection and to be administered as quickly as possible within a limited time window from symptom onset. Imaging plays a crucial role identifying patients who may benefit from MT or IVT whilst excluding those that maybe harmed. For IVT, imaging must as a minimum exclude haemorrhage, stroke mimics and provide an estimate of non-viable brain. Fo...

Defining reperfusion post endovascular therapy in ischemic stroke using MR-dynamic contrast enhanced perfusion.
CONCLUSION: MR perfusion following EVT provides accurate physiological approach to understanding the relationship of CBF, clinical outcome, and DWI growth. ADVANCES IN KNOWLEDGE: MR perfusion CBF acquired is a robust, objective reperfusion measurement providing following recanalization of the target occlusion which is critical to distinguish potential therapeutic harm from the failed technical success of EVT as well as improve the responsiveness of clinical trial outcomes to disease modification.

Association of Pre-Diabetes and type 2 diabetes mellitus with intracranial plaque characteristics in patients with acute ischemic stroke
CONCLUSIONS: Patients with pre-diabetes and T2DM had similar intracranial atherosclerotic plaque vulnerability, as demonstrated by multiple plaques, increased culprit plaque enhancement ratio and global plaque enhancement score.ADVANCES IN KNOWLEDGE: Pre-diabetes might be a risk factor for intracranial plaque vulnerability. It is necessary to monitor a slight increase in blood glucose in non-diabetes patients with acute ischemic stroke.PMID:36350061 | DOI:10.1259/bjr.20220802

Endovascular therapy of acute ischemic stroke related to tandem occlusion: comparison of occlusion and severe stenosis of the proximal cervical internal carotid artery.
CONCLUSION: Acute endovascular treatment of carotid artery tandem lesions is a technically feasible and clinically effective intervention regardless of the lesion type in proximal cervical ICA. Advances in knowledge: Our study supports the results of previous studies in which endovascular therapy has a favorable clinical outcome in carotid artery tandem occlusion.

Prediction of hemorrhagic transformation via pre-treatment CT radiomics in acute ischemic stroke patients receiving endovascular therapy
CONCLUSION: CT radiomics analysis is a valuable tool for predicting HT in AIS patients receiving EVT. It may guide the selection of patients in practice and improve procedural safety and effectiveness.ADVANCES IN KNOWLEDGE: Identification of the importance of pre-treatment CT radiomics in the prediction of HT in AIS patients after EVT.PMID:37086070 | DOI:10.1259/bjr.20220439

Carotid artery stenosis screening: Where are we now?
Abstract Stroke poses a significant burden on healthcare and is the second largest cause of death globally. Both medical and surgical interventions to reduce the risk of stroke in asymptomatic patients have been shown to be effective but identifying the target at risk population is more problematic. Screening for carotid artery stenosis offers one pathway for this, as there is some correlation between risk of stroke and extent of stenosis. Identification of patients who are at risk of cardiovascular disease as well as stroke, allows initiation of effective medical treatment of modifiable risk factors to address th...

Special report of the RSNA COVID-19 task force: systematic review of outcomes associated with COVID-19 neuroimaging findings in hospitalized patients
CONCLUSION: Among hospitalized COVID-19 patients with abnormal neuroimaging findings, those with ICH had the highest all-cause mortality; however, high mortality rates were also seen among COVID-19 patients with ischemic stroke in the acute/subacute period and leukoencephalopathy in the chronic period.ADVANCES IN KNOWLEDGE: Specific abnormal neuroimaging findings may portend differential mortality outcomes, providing a potential prognostic marker for hospitalized COVID-19 patients.PMID:33914618 | DOI:10.1259/bjr.20210149

High-resolution vessel wall magnetic resonance imaging in intracranial vasculopathies: an experience from eastern India
CONCLUSION: Adjunctive use of HR-IVWI, to clinical and luminal assessment, can significantly improve diagnostic accuracy during evaluation of intracranial vasculopathies, with its greatest utility in diagnosing in ICAD, CNS angiitis and dissection.ADVANCES IN KNOWLEDGE: HR-IVWI allows clearer etiological distinction of intracranial vasculopathies having therapeutic and prognostic implications.PMID:37066831 | DOI:10.1259/bjr.20230114
