In conclusion, time from arrival at our ED until brain CT scan exceeded 30 min in 8.2% (95% CI 6.1–10.9) of patients admitted to the ED with acute severe neurological symptoms. Time from arrival until CT scan did not exceed our quality aim in adults or elders but could be improved fo...
ObjectiveTo analyze crossed cerebellar diaschisis(CCD) after subacute phase of spontaneous cerebral hemorrhage(SPSCH)and it's relevant factors with whole-brain CT perfusion(CTP) imaging. MethodsEighty-six patients diagnosed with unilateral SPSCH by CT were prospectively enrolled in our study from July...
Whole-brain DWI-MRI was performed for reference standard final core infarct assessment, using either a 1.5 T GE Signa or 3.0 T GE MR750 MRI scanner with an eight-channel GE HR brain coil (GE Healthcare, Milwaukee, Wisconsin). Axial DWI imaging parameters included: TR 6000 ms, TE 78.2 ...
CT Perfusion Abstract The brain is one of the most metabolically demanding organs in the body but has virtually no internal energy reserves, necessitating constant high blood flow to provide oxygen and nutrients. Any perturbation in this flow is associated with significant morbidity and mortality. ...

(d) MRI demonstrates the DWI hyperintense infarct in right MCA distribution. (e) Selective right internal carotid artery angiogram shows abrupt occlusion of blood flow at the right M1 segment (arrow) confirming CTA finding. (f) Post intra-arterial therapy angiography shows restoration of cerebral ...
From an imaging-based perspective, the swelling can be observed as a “mass effect” where the infarct distorts the adjacent tissues (brain anatomical deformation) e.g. by compressing the ventricles and other CSF spaces (sulcal effacement) or causing midline shift (Fig. 1). Swelling increases ...
CT灌注成像评价颅内外动脉支架植入术的脑血流动力学变化 2009届硕上研窑生学位论文 CT灌注成像评价颅内外动脉支架植入术的脑血 流动力学变化 摘要 目的:评估CT灌注成像在颅内外动脉支架植入术脑血流动力学变化 的应用价值。 方法: 对20例经DSA证实为颅内外动脉狭窄的患者,其中男性16 例,女性4例,年龄50---71岁,...
