基于Mimics软件对颅内不规则血肿的体积测量研究

目的 探索基于交互式医学图像处理软件Mimics对脑出血不规则形态血肿体积测量的准确性与实用性。方法 收集符合纳入标准的脑出血患者60例，根据CT图像上血肿最大层面的形态分为两组：规则组25例和不规则组35例，分别采用Mimics17.0软件、多田公式法及2/3Sh法进行血肿体积测量，以2/3Sh法作为不规则血肿体积的金标准。结果 3种方法对规则血肿的测量结果比较差异无统计学意义（P>0.05），但对不规则血肿的测量结果比较，差异有统计学意义（P=0.025），其中标准法测得血肿的平均体积为49130.00±12958.98mm³，多田公式法为55961.67±13479.84mm³，Mimics软件法为46963.51±12910.95mm³，对于不规则血肿，多田公式法和Mimics软件法测量的平均误差分别为5680.00mm³、2395.93mm³，平均误差率分别为13.56%、5.90%，Mimics软件法的误差率更小，且二者误差率比较，差异有统计学意义（P=0.015）。结论 基于Mimics软件对颅内不规则血肿体积的测量方法准确、快捷，值得临床推广。

Measurement of Intracranial Irregular Hematoma Volume by Mimics Software

Objective To explore the accuracy and practicability of the volume measurement of irregular hematoma in intracerebral hemorrhage based on Mimics software. Methods According to the shape of hematoma on the maximum level of CT image,60 cases of cerebral hemorrhage patients were divided into two groups:25 of regular hematoma group and irregular 35. The volume of intracerebral hematoma was measured by the methods of Mimics17.0 software,Coniglobus formula and 2/3Sh,with the 2/3Sh method as the gold standard. Results There were no significant differences between the three methods for measurement of regular hematoma(P>0.05),but significant for the irregular(P=0.025). The average volume in 2/3Sh method was 49130.00±12958.98mm³,Coniglobus formula 55961.67±13479.84mm³,Mimics software 46963.51±12910.95mm³. For the irregular hematoma,the average volume error of two measurement respectively were:Coniglobus formula 5680.00mm³ and Mimics software 2395.93mm³.The average error rate were Coniglobus formula 13.56% and 5.90%,and the error of Mimics software was smaller (P=0.015). Conclusion Mimics software is a more accurate and quick method for intracranial hematoma volume measurement,especially for irregular hematoma,and is worthy of clinical application.
