Study on the Accuracy and Reliability of the Measurement of Hematoma Volume by Using the Coniglobus Formula for Hypertensive Supratentorial Cerebral Hemorrhage in Xizang
Objective This study aims to assess the accuracy and reliability of the coniglobus formula for calculating the volume of hematoma by comparing the measurement resluts of hypertensive supratentorial cerebral hemorrhage he-matoma by 3D-Slicer software in Xizang.Methods The non-contrast CT imaging data of 146 patients with hypertensive supratentorial hemorrhage admitted from January 2021 to December 2022 were collected,and the hematoma volumes was measured by the Coniglobus Formula and 3D-Slicer software,respectively.The hematoma volume was divided in-to＜30 mL(n=58)and ≥30 mL(n=88),and it grouped by shape was regular(n=59)and irregular(n=87).The hematoma volume meaurements were analyzed by using two methods depending on the size and shape of the hematoma.Results The data showed that the hematoma volume calculated by 3D-Slicer(41.83±22.79 mL)was higher than that caculated by the Coniglobus Formula(35.65±17.87 mL),and the difference was significant,t(145)=13.078,p＜0.001.The data of hematoma＜30mL revealed that the hematoma volume calculated by 3D-Slicer(18.76±6.67 mL)was higher than that calculated by the Coniglobus Formula(17.86±5.68 mL),which was a significant statistical difference.The hematoma volume calculated by the 3D-Slicer(57.04±15.74 mL)in the hematoma≥30mL group was higher than that calculated by the Coniglobus Formula(47.38±12.69 mL),which had significant statistical difference.The regular morphology group showed that the hematoma volume calculated by 3D-Slicer(34.29±21.90mL)was higher than that calculated by Coni-globus formula(30.37±17.36mL),which was a significant statistical difference.Meanwhile,the data of the irregular mor-phology group showed that the hematoma volume calculated by 3D-Slicer(46.95±22.06mL)was higher than that calcu-lated by Coniglobus formula(39.23±17.42mL),and there was a significant statistical difference.Conclusion In terms of the large amount of supratentorial hematoma and irregular hematoma of hypertensive intracerebral hemorrhage,the cal-culation results of the Coniglobus Formula have great error and poor accuracy.
