A diabetic patient became hypoglycemic with right hemiparesis during a contrast-enhanced CT scan. The scan showed a nonenhancing hypodensity in the left internal capsule, that disappeared the following day after treatment with glucose. This is consistent with experimental models that show selective ...

techniques would be most useful in differentiating these conditions.Several infectious, inflammatory, metabolic and vascular diseases were found with clinical presentations identical to subacute/acute ischemic cerebral infarction, which also could demonstrate only hypodensities on a non-enhanced CT scan. Howe...
AI-based HDT use was associated with an increase of 0.07 (95% CI: 0.02-0.11, p = 0.003) in DICE score accounting for individual scan and clinician effects. For scans with small lesions, clinicians achieved a mean increase in DICE score of 0.08 (95% CI: 0.02, 0.13,...
In a prospective study of 3,017 patients with transient ischemic attack or minor ischemic stroke from the Dutch Transient Ischemic Attack Trial, the presence or absence of diffuse hypodensity of the white matter on a baseline computed tomography (CT) scan of the brain was related to the ...
This ensures that the image is presented in a standard reference frame, which simplifies human interpretation of the scan. To identify acute hypodensity volumes e-ASPECTS tool compares corresponding regions of normal and ischaemic hemisphere voxel by voxel. Acute hypodensity is defined by difference ...
