Comparison of brainstem hematoma volume evaluation techniques with a novel quantitative approach

This study systematically compares various methods for calculating brainstem hematoma volume, and introduces a novel estimation method based on the maximum cross-sectional area. First, we assessed the accuracy of the Tada formula and 3D Slicer software for quantifying brainstem hematomas of different sizes and morphologies. The results revealed significant differences among methods, with the traditional Tada formula frequently overestimating hematoma volumes. We therefore propose an improved algorithm that substantially increases both the accuracy and reliability of hematoma volume assessment. Experimental results demonstrate that this new method provides greater precision and consistency when measuring the volume of irregular hematomas. These findings not only contribute to improved diagnosis and treatment of brainstem hemorrhage but also provide valuable support for future research and practical applications.
