Randomised, controlled Trial of CT perfusion and angiography compared to CT alone in thrombolysis-eligible acute ischaemic stroke patients: The penumbra and recanalisation acute computed tomography in ischaemic stroke evaluation (PRACTISE) trial

Keith W Muir, Salwa El Tawil, Alex McConnachie, Ian Ford et autres

INTRODUCTION: The role of CT angiography (CTA) and CT perfusion (CTP) in patient selection for thrombolysis <4.5 h after onset is unclear. Additional imaging may improve specificity of diagnosis by excluding stroke mimics or those without salvageable tissue, but may delay treatment. …

Multimodal versus non-contrast computed tomography for assessment of acute ischaemic stroke: the PRACTISE RCT

Keith W. Muir, Salwa El Tawil, Alex McConnachie, Alicia Murray et autres

Background Non-contrast computed tomography has low sensitivity to brain ischaemia. Higher sensitivity of computed tomography perfusion and computed tomography angiography may identify more thrombolysis-eligible patients, but the role of these imaging modalities in thrombolysis treatment decisions within 4.5 hours is unclear. We …

Computed Tomography Perfusion imaging in acute ischemic stroke

Salwa El Tawil

Stroke is the most common severe neurological disorder and is associated with high levels of mortality and disability. Ischemic stroke occurs when the blood supply to a region of the brain is interrupted for a duration that is beyond the ability of …

Observer Agreement on Computed Tomography Perfusion Imaging in Acute Ischemic Stroke

Salwa El Tawil, Grant Mair, Xuya Huang, Eleni Sakka et autres

Background and Purpose- Computed tomography (CT) perfusion (CTP) provides potentially valuable information to guide treatment decisions in acute stroke. Assessment of interobserver reliability of CTP has, however, been limited to small, mostly single center studies. We performed a large, internet-based study to …

Quantifying T 2 relaxation time changes within lesions defined by apparent diffusion coefficient in grey and white matter in acute stroke patients

Robin A. Damion, Michael J. Knight, Rose Bosnell, Peter Jezzard et autres

Abstract The apparent diffusion coefficient (ADC) of cerebral water, as measured by diffusion MRI, rapidly decreases in ischaemia, highlighting a lesion in acute stroke patients. The MRI T 2 relaxation time changes in ischaemic brain such that T 2 in ADC lesions …

Determining T2 relaxation time and stroke onset relationship in ischaemic stroke within apparent diffusion coefficient-defined lesions. A user-independent method for quantifying the impact of stroke in the human brain

Michael J. Knight, Robin A. Damion, Bryony L. McGarry, Rose Bosnell et autres

BACKGROUND AND OBJECTIVE: In hyperacute ischaemic stroke, T2 of cerebral water increases with time. Quantifying this change may be informative of the extent of tissue damage and onset time. Our objective was to develop a user-unbiased method to measure the effect of …

Thrombolysis and thrombectomy for acute ischaemic stroke

Salwa El Tawil, Keith W. Muir

The likelihood of disability-free recovery after acute ischemic stroke is significantly improved by reperfusion either by intravenous thrombolytic drug treatment or with endovascular mechanical thrombectomy in selected cases. The use of intravenous thrombolysis is limited by the short treatment window and you …
