Imaging in Acute Stroke - The Radiology Assistant
2008年6月30日 · The basal ganglia are almost always involved in MCA-infarction. Two patients with insular ribbon sign. This refers to hypodensity and swelling of the insular cortex. It is a very indicative and subtle early CT-sign of infarction in the territory of the middle cerebral artery.
Deep Basal Ganglia and Capsule Infarction - Case 1
Watershed Infarction: Axial CT scan. Note the large hypodensity in the left basal ganglia and internal capsule. Although watershed infarcts are most often thought of as areas between two major blood vessels, there is a deep watershed area between the superficial cortical arteries and the deep penetrating arteries that are both terminal branches ...
Evolution of acute infarctions in brain computed tomography (CT ...
2020年12月11日 · Brain computed tomography (CT) scans demonstrating the late effect on the brain of an acute left-sided hemiparesis without aphasia. Early stage brain CT images show a dense middle cerebral artery (MCA) sign and a poorly visible right lentiform nucleus. A brain CT after 2 days shows the right basal ganglia infarction.
Basal ganglion stroke presenting as subtle behavioural change
A non-contrast CT scan of the brain revealed a subacute isolated left basal ganglion infarction with left frontal horn mass effect (fig 1). Figure 1. Isolated left basal ganglia subacute infarct. The patient was admitted for medical management. Follow-up at 2 months revealed that his behaviour was returning towards normal.
Clinical Outcomes in Basal Ganglia Strokes Treated With …
2022年8月31日 · Basal ganglia infarcts are thought to carry worse clinical outcomes compared with other infarct patterns. We aimed to investigate whether pretreatment topographic infarct patterns including complete basal ganglia involvement versus other infarct patterns help predict mechanical thrombectomy outcomes.
Hemorrhagic infarct of basal ganglia in cardiac arrest. CT and …
We report the CT and MRI findings in two cases of hemorrhagic infarct of the basal ganglia (BG), following out-of-hospital cardiac arrest (CA). In case 1, Brain-CT realized at day 2 showed bilateral and almost symmetric hemorrhagic infarct of the BG and infarct of the tectum of the mesencephalon.
CT of the head in stroke - radlines.org
2019年7月30日 · Also called blurred basal ganglia; it is one of the most common and earliest seen sign of infarction (MCA) due to terminal blood supply pattern. The loss of the grey-white matter interface and CT hypodensity results in the ‘obscuration’ of the lentiform nucleus.
Basal ganglia infarction and hemorrhage associated with …
2023年6月1日 · Traumatic hemorrhage and infarction of basal ganglia have some similar etiology. MR imaging is indispensable for detecting cerebral infarcts due to trauma. Although posttraumatic ischemic stroke in basal ganglia is well recognized in children, basal ganglia infarction after trauma in adult patients has rarely been reported.
Early basal ganglia hyperperfusion on CT perfusion in acute …
Results: Six patients (4.3%) demonstrated hyperperfusion in the basal ganglia of the affected side (4 in the lenticular nucleus and 2 in the caudate). In all cases, the area of hyperperfusion ultimately proved to be infarcted. All patients had received …
CT radiomics features as a diagnostic tool for classifying basal ...
2020年5月15日 · The application of CT radiomics in basal ganglia infarction (BGI), for determining the onset time. The performance of the radiomic to distinguish between positive (TSS < 4.5 h) and negative (TSS ≥ 4.5 h) was good. A unique radiomic signature was constructed for use as a diagnostic tool for discriminating the TSS of BGI.
