VERFAHREN UND GERÄT ZUR ERSTELLUNG VON PENUMBRA- UND INFARKTBILDER |
摘要 |
<p>A method and apparatus for evaluating acute stroke patients and for determining whether a stroke patient will benefit from the use of thrombolysis therapy includes obtaining measurements of the cerebral blood flow and cerebral blood volume of the brain of a stroke patient, determining ischemic areas of the brain where the ischemic areas comprise the measurements of cerebral blood flow which are less than a first value and creating a penumbra-infarct map of the ischemic areas of the brain using the measurements. The infarct area corresponds to the area of the brain where cerebral blood volume is less than a second value. The penumbra area corresponds to the area of the brain where cerebral blood volume is greater than this second dvalue. The method also includes determining a ratio of penumbra size to the total of penumbra size and infarct size. When the ratio is greater than a predetermined value, the stroke patient is a candidate for thrombolysis therapy.</p> |
