Disappearance of the hyperdense MCA sign after stroke thrombolysis: implications for prognosis and early patient selection for clot retrieval

Disappearance of the hyperdense middle cerebral artery sign (HMCAS) following intravenous thrombolysis for ischaemic stroke is associated with improved outcome. Debate exists over which radiological thrombus characteristics can predict disappearance of the HMCAS after thrombolysis such as vessel attenuation or extent of thrombus length.

Utility and prevalence of imaging for underlying cancer in unprovoked pulmonary embolism

Current guidelines state that patients over 40 years of age with a first unprovoked pulmonary embolism should be offered limited screening for possible cancer and considered for intensive screening (abdomino-pelvic computed tomography and mammography), despite no evidence for the latter. The aim of this study was to evaluate the clinical utility and cost of intensive screening in routine clinical practice.

Pre-hospital notification is associated with improved stroke thrombolysis timing

Intravenous thrombolysis increases disability-free survival after acute ischaemic stroke in a time-dependent fashion. We aimed to determine whether pre-hospital notification, introduction of a CT scanner near to assessment site and introduction of out-of-hours thrombolysis services affect thrombolysis timing.
