Bilgisayarlı Tomografide Hematom Hacminin Uzman Olmayanlar Tarafından Hesaplanması için Elipsoid Yöntemler ile Cavalieri Yönteminin Karşılaştırılması

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