Navigating Supply Chain Disruptions of Iodinated Contrast Agent for Neuroimaging and How Business Intelligence Can Help the Decision Process ADULT BRAIN
SUMMARY: A recent coronavirus disease 2019–related shutdown of the main production facility of iohexol in China has led to massive shortages of iodinated contrast material across the globe. This shortage has also jeopardized neuroimaging. In this article, we describe remedies to reduce iodinated contrast material use for stroke imaging, which is its primary use in neuroimaging, that we have implemented in our hospital network.

Basilar artery occlusion: A review of clinicoradiologic features, treatment selection, and endovascular techniques
Interv Neuroradiol. 2022 Jun 12:15910199221106049. doi: 10.1177/15910199221106049. Online ahead of print.ABSTRACTBasilar artery occlusion (BAO) is an infrequent but often fatal subtype of stroke. Predicting outcomes and selecting patients for endovascular therapy (EVT) remains challenging. Advances in neuroimaging and the development of prognostic scoring systems have augmented clinical decision-making over time. Recent randomized trials, BEST (Basilar Artery Occlusion Endovascular Intervention vs. Standard Medical Treatment), BASICS (Basilar Artery International Cooperation Study), BAOCHE (Basilar Artery Occlusion CHinese...

Time to Endovascular Reperfusion and Outcome in Acute Ischemic Stroke
ConclusionAmong patients with acute ischemic stroke in routine clinical practice, shorter time to reperfusion was associated with better outcome after endovascular therapy. Standardized workflows and training in endovascular treatment techniques should be promoted nationally to reduce in-hospital delays.

Carotid vulnerable plaque coexisting with cerebral small vessel disease and acute ischemic stroke: a Chinese Atherosclerosis Risk Evaluation study
ConclusionsCarotid vulnerable plaque features coexisting with CSVDs, particularly lacunes, had a stronger association with AIS compared to carotid lesions alone in a large, symptomatic, cohort.Trial registrationClinical trial registration URL:http://www.clinicaltrials.gov, unique identifier: NCT02017756Key Points• Carotid vulnerable plaque features coexisting with cerebral small vessel diseases, such as lacunes, had a stronger association with acute ischemic stroke compared to single diseases in symptomatic patients.• A comprehensive assessment of coexisting cerebrovascular diseases may help stratify the risk of acute ischemic stroke.

Global research trends in COVID-19 with MRI and PET/CT: a scoping review with bibliometric and network analyses
ConclusionCOVID-19 pandemic is still spreading worldwide, and the knowledge about its different facets continues advancing. MRI and PET/CT are being used in more than 50% of the selected studies; research trends span seven categories, no only the diagnostic but others like socio-economic impact and pathogenesis Developed countries had an advantage by having hospitals with more resources, including MRI and PET/CT facilities in the same institution to supplement basic assessment in patients with COVID-19.

Spectrum of neuroimaging findings in COVID-19.
Abstract An outbreak of corona virus disease 2019 (COVID-19) began in China in December 2019, and rapidly spread to become a worldwide pandemic. Neurological complications encountered in hospitalized patients include acute arterial ischemic cerebrovascular stroke, cerebral venous thrombosis, critical illness-associated cerebral microbleeds, hypertensive hemorrhagic posterior reversible encephalopathy, meningoencephalitis/flare up of infections, flare up of multiple sclerosis, acute disseminated encephalomyelitis, cerebral hemodynamic/hypoxic changes such as watershed ischemic changes and hypoxic ischemic encephalo...

Pressing Issues in COVID-19: Probable Cause to Seize SARS-CoV-2 for Its Preferential Involvement of Posterior Circulation Manifesting as Severe Posterior Reversible Encephalopathy Syndrome and Posterior Strokes ADULT BRAIN
SUMMARY: Since December 2019, a novel Severe Acute Respiratory Syndrome coronavirus 2 from China has rapidly spread worldwide. Although respiratory involvement is the mainstay of coronavirus disease 2019 (COVID-19), systemic involvement has recently drawn more attention. In particular, a number of recent articles have shed light on the nervous system as one of the possible targets. At our institution, we observed 15 patients with acute brain vascular manifestations; most interesting, we had a higher prevalence of the posterior circulation acute impairment. In our series, 7 patients had acute posterior cerebral injury: 1, h...

Cerebrovascular Disease in COVID-19 ADULT BRAIN
We report a case of COVID-19 with acute ischemic stroke. To our knowledge, this is the first reported case of COVID-19-related cerebral infarcts that includes brain imaging at multiple time points and CT angiography. There is a growing body of published evidence that complications of COVID-19 are not limited to the pulmonary system. Neuroradiologists should be aware of a wide range of neurologic manifestations, including cerebrovascular disease.
