We estimated transfer rates using non-contrast head CT and stroke severity to select patients to be transferred to larger centers for evaluation. Methods We identified all AIS among residents of the study region in 2010. Only cases age ≥ 18 with baseline mRS 0–2 that presented to an ED ...
The hyperdense artery sign on noncontrast head CT is thought to be one of the earliest and most useful signs of intra-arterial clot and probable (clinical) stroke. It should be evaluated in the context of the clinical scenario. Rigorous criteria should be applied in order to reduce potential...
Neuviz 16). NCCT was performed in a head holder by an axial technique with 120 kilovolts (peak), 150 mA, and 5-mm thickness reconstruction. MDCTA was performed by scanning from the base of the C1 body to the vertex using the following parameters: pitch (1.2); collimation...
Dual-energy CT (DECT) material decomposition techniques may better detect edema within cerebral infarcts than conventional non-contrast CT (NCCT). This study compared if Virtual Ischemia Maps (VIM) derived from non-contrast DECT of patients with acute ischemic stroke due to large-vessel occlusion (...
Stroke is one of the major threats to human health, and it is the third leading cause of death in the world with high mortality and disability rate [1,2,3]. Non-contrast computed tomography (NCCT) is deemed as the first choice for all stroke diagnosis due to its relative high speed, ...
Hot Topic: Axial "Shuttle Mode" CT Perfusion Acquisition Increases Coverage and Decreases Radiation and Contrast Dose Without Loss of Visual Diagnostic Acc... PURPOSE Using post-processing software from two different commercial vendors for CT perfusion (CTP) map construction in acute stroke patients, ...
目前尚不清楚多参数双能量CT(DECT)提供的额外信息是否能改善侵袭性大梁状大块型(MTM)肝细胞癌(HCC)的非侵入性诊断。 Conclusions 结论 A DL radiomics nomogram derived from multiparametric DECT accurately predicted the MTM subtype in patients with HCC. ...
In this study, we developed and evaluated a fully automatic deep-learning solution to accurately and efficiently segment and quantify hemorrhage volume, using the first non-contrast whole-head CT images taken during clinical stroke management. We also compared the performance of this novel U-Net con...
To assess ischaemic penumbra through the post-processing of the spectral multiphasic CT Angiography (mCTA) data in acute ischaemic stroke (AIS) patients. Thirty one consecutive patients strongly suspected of severe Middle Cerebral Artery AIS presenting less than 6 h after onset of symptoms or with ...
stroke, heart failure, or chronic obstructive lung disease. Though not representative of a completely healthy cohort, this initial effort has laid the groundwork for developing a comprehensive total-body normative database, a crucial step in expanding the potential of PET imaging in systemic health ...
