Noninvasive In Vivo Thrombus Imaging in Patients With Ischemic Stroke or Transient Ischemic Attack
CONCLUSIONS: 18F-GP1 positron emission tomography and computed tomography angiography is a novel noninvasive method of identifying in vivo cerebrovascular thrombosis, which holds major promise in understanding the role and origin of thrombosis in stroke.REGISTRATION: URL: https://www.CLINICALTRIALS: gov; Unique identifier: NCT03943966.PMID:37439259 | DOI:10.1161/ATVBAHA.122.318204

Comparison of diffusion weighted imaging b0 with T2*-weighted gradient echo or susceptibility weighted imaging for intracranial hemorrhage detection after reperfusion therapy for ischemic stroke
ConclusionDWI b0 is inferior for detection of ICH compared to T2*GRE/SWI, especially for smaller and more subtle hemorrhages. Follow-up MRI protocols should include T2*GRE/SWI for detection of ICH after reperfusion therapy.

A brain CT-based approach for predicting and analyzing stroke-associated pneumonia from intracerebral hemorrhage
DiscussionOur findings suggest that our method is effective in classifying the development of pneumonia based on brain CT scans. Furthermore, we identified distinct characteristics, such as volume and distribution, of ICH in four different types of SAP.

Using a CT Angiography Artificial Intelligence Carotid Plaque Morphology Model to Predict Stroke
The gold standard for determining carotid artery stenosis is to calculate stenosis using the North American Symptomatic Carotid Endarterectomy Trial criteria and ultimately plan for medical vs surgical management based on percent stenosis and symptomatic status. Few studies have assessed plaque morphology as an additive tool for stroke prediction. Our study uses an artificial intelligence software in conjunction with a patient's computed tomography (CT) scan of the neck to create a three-dimensional (3D) model of the carotid artery and assess plaque morphology including calcification, intraplaque hemorrhage, matrix, and pe...

Minimally Invasive Intracerebral Hemorrhage Evacuation Improves Pericavity Cerebral Blood Volume
This study aims to quantify blood volume changes in the perihematomal parenchyma and pericavity parenchyma after minimally invasive intracerebral hemorrhage evacuation (MIS for ICH). Thirty-two patients underwent MIS for ICH with pre- and post-operative CT imaging and intraoperative perfusion imaging (DynaCT PBV Neuro, Artis Q, Siemens). The pre-operative and post-operative CT scans were segmented using ITK-SNAP software to calculate hematoma volumes and to delineate the pericavity tissue. Helical CT segmentations were registered to cone beam CT data using elastix software. Mean blood volumes were computed inside subvolume...

Dual-Layer Detector Cone-Beam CT Angiography for Stroke Assessment: First-in-Human Results (the Next Generation X-ray Imaging System Trial) INTERVENTIONAL
CONCLUSIONS: In a single-center stroke setting, dual-layer detector cone-beam CTA virtual monoenergetic images are noninferior to CTA under certain conditions. Notably, the prototype is hampered by a long scan time and is not capable of contrast media bolus tracking. After excluding examinations with such scan issues, readers considered dual-layer detector cone-beam CTA noninferior to CTA, despite more artifacts.

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

Time to ct scan imaging after symptom onset among ischeamic stroke patients presenting to a quaternary hospital in ghana
This study sought to determine the time of onset of symptoms to the time a CT imaging was done among patients presenting with acute stroke at the Korle-Bu Teaching Hospital.

Ocular and systemic determinants of perifoveal and macular vessel parameters in healthy African Americans
Conclusions When interpreting OCTA images in a clinical setting, it is important to consider the effects ocular and systemic characteristics may have on the macular microcirculation.

Evaluation of pure subarachnoid hemorrhage after mechanical thrombectomy in a series of 781 consecutive patients
CONCLUSION: We suggest that dual-energy computed tomography could better distinguish between blood and pure contrast stagnation. Still, SAH was not associated with an unfavorable outcome in stroke patients undergoing thrombectomy.PMID:36916147 | DOI:10.1177/15910199231163046
