Vessel Wall Imaging in Cryptogenic Stroke
Radiol Clin North Am. 2023 May;61(3):491-500. doi: 10.1016/j.rcl.2023.01.006. Epub 2023 Feb 20.ABSTRACTCryptogenic strokes are symptomatic cerebral ischemic infarcts without a clear etiology identified following standard diagnostic evaluation and currently account for 10% to 40% of stroke cases. Continued research is needed to identify and bridge gaps in knowledge of this stroke grouping. Vessel wall imaging has increasingly shown its utility in the diagnosis and characterization of various vasculopathies. Initial promising evidence suggests rational use of vessel wall imaging in stroke workup may unravel pathologies that ...

Current Evaluation of Intracerebral Hemorrhage
Radiol Clin North Am. 2023 May;61(3):479-490. doi: 10.1016/j.rcl.2023.01.005. Epub 2023 Feb 20.ABSTRACTAdvanced imaging is currently critical in diagnosing, predicting, and managing intracerebral hemorrhage. MD CT angiography has occupied the first line of evaluating patients with a clinical diagnosis of a stroke, given its rapid acquisition time, high resolution of vascular structures, and sensitivity for secondary causes of ICH.PMID:36931764 | DOI:10.1016/j.rcl.2023.01.005

Advanced Imaging for Acute Stroke Treatment Selection: CT, CTA, CT Perfusion, and MR Imaging
Radiol Clin North Am. 2023 May;61(3):445-456. doi: 10.1016/j.rcl.2023.01.003.ABSTRACTThere is constant evolution in the diagnosis and treatment of acute ischemic stroke due to advances in treatments, imaging, and outreach. Two major revolutions were the advent of intravenous thrombolysis in the 1990s and endovascular thrombectomy in 2010s. Neuroimaging approaches have also evolved with key goals-detect hemorrhage, augment thrombolysis treatment selection, detect arterial occlusion, estimate infarct core, estimate viable penumbra, and augment thrombectomy treatment selection. The ideal approach to diagnosis and treatment ma...

Evaluation of Collateral Circulation in Patients with Acute Ischemic Stroke
Radiol Clin North Am. 2023 May;61(3):435-443. doi: 10.1016/j.rcl.2023.01.002. Epub 2023 Feb 18.ABSTRACTThe cerebral collateral circulation is an increasingly important consideration in the management of acute ischemic stroke and is a key determinant of outcomes. Growing evidence has demonstrated that better collaterals can predict the rate of infarct progression, degree of recanalization, the likelihood of hemorrhagic transformation and various therapeutic opportunities. Collaterals can also identify those unlikely to respond to reperfusion therapies, helping to optimize resources. More randomized trials are needed to eval...

Ischemic Infarction in Young Adults
Radiol Clin North Am. 2023 May;61(3):415-434. doi: 10.1016/j.rcl.2023.01.010. Epub 2023 Feb 19.ABSTRACTIschemic strokes in young adults are increasing in incidence and have emerged as a public health issue. The radiological features are not only diagnostic in identifying ischemic infarctions but also provide important clues in the investigation of the underlying causes or in the identification of risk factors. According to the different imaging patterns associated with ischemic stroke in young adults, the causes can be classified into 5 categories: cardioembolism, large vessel vasculopathy, small vessel vasculopathy, toxic...

Pearls and Pitfalls of Carotid Artery Imaging: Ultrasound, Computed Tomography Angiography, and MR Imaging
Radiol Clin North Am. 2023 May;61(3):405-413. doi: 10.1016/j.rcl.2023.01.001. Epub 2023 Feb 9.ABSTRACTStroke represents a major cause of morbidity and mortality worldwide with carotid atherosclerosis responsible for a large proportion of ischemic strokes. Given the high burden of the disease , early diagnosis and optimal secondary prevention are essential elements in clinical practice. For a long time, the degree of stenosis had been considered the parameter to judge the severity of carotid atherosclerosis. Over the last 30 years, literature has shifted attention from stenosis to structural characteristics of atherosclerot...
