Correlative ROI Calculation of MCAs: Another Promising Primary Sign of Acute Infarction?

The purpose of this project was to calculate the ROI of the middle cerebral artery (MCA) in patients with acute stroke to establish if this measurement could be used as another primary sign of infarction even if other established primary signs of infarction are absent. CT brain scans of 465 patients, who presented in the emergency room in the first six hours after the onset of symptoms, were studied retrospectively. Two polygonal ROIs were drawn on the M1 segments of both middle cerebral arteries and three parameters were calculated automatically: HU density, volume and surface of the corresponding artery segment.
