SYSTEMS AND METHODS FOR DIAGNOSING STROKES

摘要

The invention relates to systems and methods for diagnosing strokes. In particular, systems and methods for acquiring timely patient status information are described that enable a physician to make diagnostic and treatment decisions relating to ischemic and hemorrhagic strokes. The systems and methods enable the efficient and quantitative assessment of arterial collaterals within the brain for aiding these decisions in the case of ischemic strokes. In the case of hemorrhagic strokes, the systems and methods are effective in determining if there is a leak and what is the rate of leaking.

1. A method of imaging the brain within a patient diagnosed as potentially suffering a stroke, the method for deriving information about blood flow within the brain the method comprising the steps of:
a) injecting a bolus of contrast agent into the patient; b) obtaining a set of computed tomography (CT) images of the patient's brain at different levels at a specific time period, t, after step a); c) repeating step b) n times to obtain at least one additional set of CT images of the patient's brain at different levels at time period t after step b), wherein n is at least one and each set of CT images is defined as a phase of images, P1-Pn; d) displaying each phase of CT images from steps b) and c) as a time-sequenced series of images.
