New Measuring Method for the Volume of Intracerebral Hematoma

For the measurement of intracerebral hematoma volume, the medical staff prefers to use Dotian formula to estimate the volume for convenience. Dotian technique is a method that considers hematoma as a solid to measure, although the majority of hematomas are not in the form of regular solids, and different hematoma forms are seen when computed tomography (CT) scans are taken at different baseline, thickness, or layers. Hence, the Dotian formula cannot fully meet the clinical requirements .The author has written a VB program based on a polygon formula method, which depicts points through the CT images. Each CT is approximated as a polygon by us, and then we can use this program to calculate each CT image’s area and each layer’s volume according to the area multiplied by the thickness. We could use the hematoma volume measured by computer software as relatively accurate standard, and compare with hematoma volume calculated by the polygon formula to verify the accuracy of this method. It has important clinical significance and practical value.
