3D_slicer软件对高血压脑出血患者早期血肿准确性的评估分析

目的比较多田公式与3D_slicer软件评估高血压脑出血患者早期血肿准确性.方法回顾性分析103例高血压基底节区脑出血患者分别采用多田公式、3D_slicer软件测量所得血肿体积资料,依据3D_slicer软件所测得体积分为A组(血肿量<30ml,n=31)、B组(血肿量为30~60ml,n=38)、C组(血肿量>60ml,n=34),按形状分为规则组(n=33)、不规则组(n=60)、分叶状组(n=10),对两种方法测量结果进行比较.结果多田公式、3D_slicer软件测量血肿体积(51.89±5.26)ml、(43.75±4.52)ml,差异有统计学意义(P<0.05),多田公式较3D_slicer软件平均测量差异为8.14ml,两种测量方法所得血肿体积相关性不显著(P>0.05);依据血肿大小分组,多田公式较3D_slicer软件测量差异分别为A组2.28ml、B组6.69ml、C组17.55ml;依据血肿形状分组,多田公式较3D_slicer软件测量差异分别为规则组2.93ml、不规则组6.04ml、分叶状组6.36ml.结论高血压脑出血患者采用传统多田公式评估早期血肿情况准确性低,尤其对于形状不规则血肿计算差异较大,而采用3D_slicer软件测量脑内血肿体积具有准确、快捷、免费等优点,在判断预后、准确告知患者病情有积极作用.

Objective To compare the accuracy of Tada formula versus 3D_slicer softwarein evaluating early enlargement of hematoma in patients with hypertensivecerebral hemorrhage. Methods The date from 103 patients with hypertensive basal cerebral hemorrhage using the Tada formula and 3D_slicer software to measure the hematoma volume were analyzed retrospectively. According to the volume of hematoma measured by 3D_slicer software,the patients were divided into group A(hematoma volume<30 ml,n=31),group B(hematoma volume of 30 ~ 60 ml,n=38)and group C(hematoma volume>60 ml,n=34). According to the shape,they were divided into the regular group(n=33),the irregular group(n=60) and the lobulated group(n=10). Measured results of the two methods were compared. Results The volume of hematoma measured by Tada formula and 3D_slicer software was(51.89±5.26)ml and(43.75±4.52)ml(P<0.05). The average measurement error of Tada formula was 8.14 ml, the volume correlation of hematoma obtained by the two methods was not significant(P>0.05). Grouping according to the size of hematoma showed that the measurement errorof Tada formula was 2.28 ml for group A,6.69 ml for group Band 17.55ml for group C,respectively. The error rateswere 12.74%,16.65% and 26.49%,respectively. Grouping according to the shape of hematoma showed that the measurement error of Tada formula was 2.93ml in the regular group,6.04ml in the irregular group and 6.36ml in the lobulated group,and the error rates were 7.88%,11.97% and 8.48%,respectively. Conclusion For patients with hypertensive cerebral hemorrhage,the accuracy of Tada formula is low in evaluating early enlargement of hematoma, especially for the calculation of irregular hematoma,the error is relatively larger. The use of 3D_slicer software to measure the volume of intracerebral hematoma is accurate,fast,free,etc,and has a positive effect in judging the prognosis and accurately informing the patient's condition.
