Worldwide, stroke is a leading cause of death and disability. Recombinant tissue
plasminogen activator (rtPA) was approved a decade ago for the treatment of acute ischemic …

In 1979, just 8 years after Godfrey Hounsfield's introduction of CT, Leon Axel first proposed a
method for determining tissue perfusion from dynamic contrast enhanced CT data [1]. Due to …

The purpose of this study was to determine the prognostic accuracy of perfusion computed
tomography (CT), performed at the time of emergency room admission, in acute stroke …

Imaging plays an essential role in identifying intracranial injury in patients with traumatic
brain injury (TBI). The goals of imaging include (1) detecting injuries that may require …

Background and Purpose—Computed tomographic perfusion represents an interesting
physiological imaging modality to select patients for reperfusion therapy in acute ischemic …

Perfusion computed tomography (CT) is a relatively new technique that allows rapid
qualitative and quantitative evaluation of cerebral perfusion by generating maps of cerebral …

Traumatic brain injury (TBI) is a common condition with many potential acute and chronic
neurological consequences. Standard initial radiographic evaluation includes noncontrast …

Stroke is a heterogeneous syndrome caused by multiple disease mechanisms, but all result
in a disruption of cerebral blood flow with subsequent tissue damage. This review covers the …

Thrombolytic therapy has led to a higher proportion of patients presenting to hospital early,
