This finding was not appreciated on the initial non-contrast CT scan by the radiologist from the outside hospital. One other patient had some sedimentation of blood in the posterior horns. Two other patients had ambiguous findings: suspicion of small amount of blood in the pentagon in two ...
Computed Tomography (CT)is a noninvasive X-ray that provides detailed images of anatomical structures within the brainand to detect any bleeding. CT angiography (CTA) involves the injection of contrast into the blood stream to view the arteries of the brain. Lumbar punctureis an invasive procedur...
In contrast, the rats in the SAH+VEH group showed a much higher level of miR-138 (Figure 2C) than the rats in the SHAM group, but the treatment with MEL obviously decreased the expression of miR-138. Therefore, H19, miR-675, and miR-138 were all differentially expressed upon the ...
Ischemic stroke presents as a sudden loss of neurologic function, often manifest as a deficit in one side of the body with sparing of function on the contralateral side. Stroke rarely presents as a bilateral phenomenon in the absence of severe reduction in...
Xe-CT In Xe-CT, inhaled stable xenon gas is used as a contrast agent [30]. Xenon is an inert, radiopaque gas that diffuses freely over the blood-brain barrier. A gas mixture with 28% xenon was delivered to the patient via the ventilator. After two unenhanced baseline scans, repeated ...
Patient care in a neurointensive care unit (neuro-ICU) is challenging. Multidrug-resistant organisms (MDROs) are increasingly common in the routine clinical practice. We evaluated the impact of infection with MDROs on outcomes in patients with subarachno

radiographic model SAHV that measures basal cisternal SAH blood volume using a derivation of the ABC/2 ellipsoid formula (A=width/thickness, B=length, C=vertical extension) on noncontrast CT, which we previously demonstrated is comparable to pixel-based manual segmentation on noncontrast CT. Data...
The purpose of this study was to establish the relationship between different measures of brain perfusion made on dynamic-contrast CT reconstructions performed as soon as SAH has been diagnosed and the severity of the bleeding determined by the clinical grade, the extent of the bleeding and the ...
