Abstract
An electronic capillary index scoring (eCIS) method is provided. The method includes providing a co-registered diagnostic cerebral angiogram (DCA) and quantifying an actual capillary blush area of a portion of the diagnostic cerebral angiogram representing an ischemic hemisphere. The method further quantifies an expected capillary blush area of the portion of the diagnostic cerebral angiogram representing the ischemic hemisphere. An eCIS is calculated by dividing the quantified actual capillary blush area by the quantified expected capillary blush area.
Claims20
A capillary index scoring method, comprising the steps of:
- providing a co-registered diagnostic cerebral angiogram in frontal view or lateral view;
- quantifying an actual capillary blush area of a portion of the diagnostic cerebral angiogram representing an ischemic hemisphere, wherein the step of quantifying an actual capillary blush area comprises recognizing boundaries of an ischemic region of the ischemic hemisphere, and calculating the actual capillary blush area within the boundaries;
- quantifying an expected capillary blush area of the portion of the diagnostic cerebral angiogram representing the ischemic hemisphere, wherein the step of quantifying an expected capillary blush area comprises recognizing boundaries of an bony landmark of the ischemic hemisphere, calculating a surface area withing the boundaries of the bony landmark of the ischemic hemisphere, and dividing the area within the boundaries of the bony landmark of the ischemic hemisphere by a constant relating the area within the boundaries of the bony landmark of the ischemic hemisphere to an area of a non-ischemic hemisphere;
- and
- dividing the quantified actual capillary blush area by the quantified expected capillary blush area.
