dc.description.abstractObjective: Intracerebral haemorrhages account for approximately 20% of all strokes and have higher morbidity and mortality, nearly 60% ofpatients die within a year, and 20% of the survivors live disabled. The volume of intracerebral haemorrhage has a strong association with theunfavourable outcome; therefore, fast and accurate measurement of the volume is crucial for clinical decision making. This study aimed to comparethe ellipsoid methods and the Cavalieri method for calculating intracerebral hematoma volumes by physicians without special education oncomputed tomography assessment.Methods: The hematoma volumes in the computed tomography images of 30 consecutive patients were measured via ellipsoid methods andthe Cavalieri method. The calculated volumes of hematoma by the four methods were compared statistically.Results: The median haematoma volumes (interquartile ranges) for ‘Cavalieri’, ‘prolate ellipse (abc)’, ‘prolate sphere (aac)’ and ‘sphere (aaa)’methods were 23.2 (27.4), 37.2 (45.8), 22.1 (30.75), and 14.4 (31.87) respectively. A Friedman repeated measures ANOVA test determined that theresults of the four methods to evaluate the haematoma volume differ significantly (p<0.001). A Durbin-Conover test demonstrated that the abcmethod was significantly different from other methods and that no significant difference among other methods was present. A week agreement wasfound between methods (Kendall’s W = 0.3).Conclusion: Apart from the ‘prolate ellipse (abc)’ method, which tends to over-calculate the volume, three methods out of four seem feasible to usefor physicians without special education on computed tomography assessment.en_US
